To His Excellency, the Honorable William D. Stephens, Governor of California. Sir: I have the honor to transmit herewith Bulletin Xo. 84 of the State Mining Bureau, being the Third Annual Report of the State Oil and Gas Supervisor. The law providing for the protection of California oil deposits against water and other damage following improper development methods is an outgrowth of local conditions, and had little or no precedent to follow. The underlying motive is to gather and arrange facts as to under- ground conditions and supervise oil field operations, as far as possible, in an advisory manner. Previous to the enactment of this law, but scant attention had been given to the gathering and comparing of facts, and operations were largely conducted upon theories as to underground conditions. As the theories were usually advanced by men of long experience, the ordinary usage assumed the misnomer of "practical methods." Very gratifying results have followed three years of educational work, during which time both the department and the oil operators have advanced in knowledge of natural laws governing underground con- ditions. As was to be expected in such work, a few operators liave not readily adopted suggested changes in operations, and some do not yet realize their responsibility in protecting the oil fields, in which the public is vitally interested. Some changes in the law, therefore, will be necessary in order to make it thoroughly effective. Such changes will not affect individuals or corporations who are more interested in the spirit rather than the letter of the law. Respectfully submitted. Fletcher Hamilton, State Mineralogist. IMr. Fletcher Hamilton, State Mineralogist. Sir: In transmitting the Third Annual Report of the work of the Department of Petroleum and Gas, I believe it may be well to call atten- tion to the fact that the usefulness of the department to the public requires absolute impartiality in dealing with the various producers, both large and small. It is a pleasure to record that the department has been given a free hand to discharge its duty. Respectfully submitted. R. P. McLaughlin, State Oil and G.'is Suprrvisor. 8 STATE OIL AND GAS SUPERVISOR. Public interest requires further legislation to compel proper opera- tions by such concerns as are not receptive to educational methods of legal administration and still fail to recognize their obligations in the matter of protecting the oil deposits of California. In our previous reports', considerable attention was devoted to explaining and illustrating the elementarj^ features upon which thorough development and protection of the oil fields rest. The present report omits the elementary principles and merely recites the actual work and developments of the past year. Such new principles as we have been able to thoroughly study are also described. It should be particularly noted that a complete list of all operations upon which the department has passed is given in this and previous reports. The facts thus recorded will be found useful to careful investi- gators. The policy of issuing recommendations to operators, rather tluni orders, has been continued. This provides elasticity in the system of .supervising oil field operations, so that facts or conditions, subsequently discovered, can be informally presented by an operator and a supple- mentary recommendation issued. The greater portion of our work is carried on informally by consultation between field representatives of the department and the operators. The written records, however, cover all proposals and recommendations. It was necessary to issue only three formal orders : Order Xo. 4. relative to State Consolidated Oil Company, Llovd well No. 2.- Order Xo. 5. relative to Union Oil Companv. International well Xo. 7.^ Order Xo. 6. relative to Petroleum ^Midway Compau}', Ltd.. Darlington well Xo. 1.* There were, however, many instances in which the department did not approve operations, and the written records have merely been kept clear and complete so as to provide for such future legal action as may be necessary. Some of the operations which were not approved may never cause serious damage, and it is believed that ultimately more good will be accomi)lished by the past liberal or educational administration of the law than by drastic legal action. Formal orders, in general, have been issued on the following grounds : (1) At the request of the operator: (2) Where great and immediate damage seemed probable; (3) Where it appeared that the operator was defiant of legal restrictions?.

THIRD ANNUAL REPORT. 9 Legal action was taken in two instances^ only, namely : against Thomas A. Sloeum; and againstl. W. Fuqua, as president, general manager and agent of the Red Star Petroleum Company. The first action was taken on account of repeated failure to file records and was dismissed when the records were produced. The second action was taken where it appeared that deliberate attempts were being made to conceal information obtained during drilling operations. Con- viction was not obtained. A change in the statutory provisions govern- ing the department in such matters is necessary. A marked improvement in field operations has taken place throughout the state since the enactment of the law, and more care is given by opera- tors to the details necessary to the proper drilling of wells. On the other hand, attention is called to the fact that improvement has not been so widespread that legal supervision is no longer needed. Two new fields (Montebello and Casmalia), developed in the past two years, have already encountered water in menacing quantities. These fields are in the hands of large operators, and the difficulties follow directly upon their failure to co-operate with the department in the matter of careful engineering study and control. As has been repeatedly stated, the department has neither the facilities nor the inclination to originate l>lans directing, in detail, the operations of any concern. Proposed operations, particularly those of great volume, should lie accompanied by carefully compiled data, supporting a well-considered plan. Tlie con- cerns above mentioned luive greatly retarded and discredited the admin- istration of the law by attempting to shift upon the department the burden of planning operations. Maps of all the oil fields have been completed and are on sale at our various offices at prices which merely cover the cost of blue printing. These maps are revi.sed from time to time to show the latest develop- ments. Such information has not, heretofore, been readily available to the public. Models .showing the geological and mechanical conditions have been constructed- and displayed at our various field offices. Tlie number of persons calling for the purpose of inspecting these models, particu- larly at our Los Angeles office, indicates that the models are useful to llie public, besides being necessary in the work of the department. Office buildings were constructed at Coalinga and Taft, which have facilitated our work during the latter part of the year. The l)uik1ing at Taft will have to be enlarged in order to display models, whicli can now be rapidly assembled and made available for public use. >The People of the Shite of Califoiiiiii v. Thomas A.

Several public meetings were held for the purpose of discussing details of certain field operations. A meeting at Los Augeles\ for the purpose of considering the use of mud fluid, was well attended, and several interesting, detailed papers were presented, and served as a basis for discussion. However, subsequent field operations demonstrated that the suggestions were not acted upon. A meeting at San Francisco, for the purpose of discussing the subject of proper and economical spac- ing of wells-, brought out but little definite information beyond that com- piled by the department". Several large concerns Avere not represented by engineers or others who were prepared to present detailed evidence that the subject had been seriously considered. While the subject of the most economical spacing of wells might, at first glance, appear to be abstract and theoretical, it will be found that systematic observations, governed by common sense, will afford valuable information. It has long been recognized that wells drain territory for varying distances*, and it is self-evident that, if wells are too closely spaced, some of them are merely a waste of labor and material. The department has made no extended or systematic investigation of the subject, but it has observed some striking instances. One of the best examples coming to our attention is shown by the accompanying diagram (Fig. 1) . which shows the production of four wells over a period of nearly four years. It will be noted that, as each new well was com- pleted there was a marked decline in productions of wells already pro- ducing. The new well drew much of its production from areas previously supptying adjoining wells. As a matter of fact, one well, or at the utmost two. would have produced as much oil. The article by E. A. Starke (pp. 107 to 109. post), describing a process for the increased utilization of heavy oil, should be of partic- ular interest to many producers. The policy of publishing original articles of public interest was established in our previous reports^. Needless expense in oil field operations has repeatedly been mentioned in reports of this department. The special report by R. E. Collom, com- paring results obtained from various methods of shutting off water, fur- nishes data w^hich can be used to reduce present losses to an amount at least equal to the total expenditures by this department. There has been a disposition, in some quarters, to belittle or discount previous statements as to inefficiency. It would appear unnecessary to do more than merely point out the results obtained by various large pro- ducers, as shown in the following table. It will be noted that the per- 'Pp. 77 to IOC, post.

Stringent rules were not adopted l)eeause it appeai'cd no definite evi- dence had been collected l)y the supporters of eilher tlie rotary or (•a])le tools. It Avas also apparent that many clainumts were unduly prejuilieed in favor of one method or the other. The figiire.s now available show that failures to shut oft water occur very nnu-h oftener with rotary tools than with cable tools. The extraordinary difficulty in properly drilling and protecting the Sunset field was pointed out in formal order Xo. 5, relative to Union Oil Company well No. 7, International. This order was held by some individuals to be too stringent. Attention is now called to the fact that only one-half of the attempts made in the Sunset field to shut off water in rotary holes are successful. In the case where the department took legal action, charging falsifi- cation of drilling records, the future of the very productive Montebello field was at stake. The figures at hand now .show tliat more than a third of the attempts to shut off water are failures, 'i'herefore the de{)artment luis no apologies to offer for exhausting all legal methods in attempting to protect this field. Both the advantages of careful engineering work and the disadvantage of rotary tools are clearly set farth by the figures showing the percentage of failures in the Coalinga field. It will be noted that the difference between the success and failure of a shut-off frequently depends upon determining, within five feet, the depth at which a shut-off should be attempted. This can not be determined without geological and engineer- ing work, and requires a log more accurate than can be obtained when rotary tools are used. The department has frequently been called upon to make definite blanket rulings requiring the use of cement at all wells. We have avoided taking such a position on account of the lack of definite facts. It is, therefore, of special interest to note that a comparison of results shows that cement is not always necessary. In other words, the mere use of cement is not automatically a cure or preventative for all water troubles. Some operators have argued that the use of large quantities of cement would protect all oil formations left back of a string of casing. This argument has been advanced particularly by some of the concerns having poor records for simple shut-off at the shoe of casing. Therefore, the burden of proof remains upon them. There are several cementing concerns who do work by contract. Their varying percentage of success is shown by the figures. There are numerous mechanical details which must be given cai-eful attention if successful shut-offs are to be obtained. Sometimes operators 14 STATE on- AND C,.\S SUPERVISOR. have indicated that the department is too strict. Sucli opinions are nsually hold by persons who liave not had wide exporieiiee in observing such work, and tlu; details set fortli by Mv. CoUoiii will .show the care- ftd reader thnt llu'i-e is a l)asis of fact for our I'cftuircmcnts. STATISTICS OF OIL PRODUCTION. Monthly statistics for various fields and for the entire state are given here for the purpo.se of bringing- records, previously published in Bulle- tins Nos. 69, 73 and 82, down to date. The figures as in previous pub- lications, are those collected by the Standard Oil Company. They closely check those collected by the Independent Oil Producers' Agency and also the figures collected b}^ this department in the form of sworn statements. The Lost Hills and Belridge fields show the greatest decline in average daily production per well. All fields, except Lompoc and Santa Maria and Whittier-Fullerton, show a decline in production. It has already been noted that the increases for the Lompoc and Santa j\Iaria field and the Whittier-Fullerton field are due, respectively, to the Casmalia and IMontebello fields. KERN RIVER.

PROVED OIL LAND AND DEGREE OF DEVELOPMENT. The extent of owiier.ship or coiitfol of proved oil laud, aiul degree of development, is diown in the following' table. A similar tabnlation was made by the writer for the year 1914, in Bulletin 69^. The amounts given under ''acres per well" in the present tabulation show to what extent the proved lands of various concerns have been drilled. There lias been an increase of 20 per cent in the total proved acreage of the state, and an increase of 10 per cent in the number of wells producing. It nuist he remembered that the figures of four years ago were compiled under conditions less favorable to accuracy than exist now. Therefore the comparisons must be liberally interpreted.

AND GAS SUPERVISOR. Compariisou of the present extent and development of our proved laud with that of four years ago affords some very valuable information. The enlargment of the total proved acreage is probably the most significant and gratifying feature. It emphasizes the fact that it is extremely difficult to forecast the extent of our oil resources, and should serve to restrain pessimistic forecasters. On the other hand, it nuist be realized that the oil resources have a definite limitation which for- •bids wasteful production or use. The acreage per well has not greatly changed, and shows that there still remains a wide margin for development of the proved land. The yield per well will, of course, be expected to decline along with the increased development. The margin for development of proved land remaining for each of the various large concerns is of interest to investors and the public ; but, of course, this margin must be liberally interpreted. The increase in the number of wells owned by the various large con- cerns includes the wells acquired by purchase and also new wells drilled. The percentage of the total proved area owned by the various large concerns has not greatly changed. In other words, the danger of monopoly of the oil lands is no nearer than it was four years ago. The great increase in the proportion of oil produced by the Standard Oil Company — 22.6 per cent as against 9.4 per cent — is evidence of the reward following active development campaigns. The fact that just nine concerns own or control as much as 65 per cent of the oil land in the state, which yields fully 72 per cent of the production of the state, is ample explanation of the policy of this depart- ment in setting forth in considerable detail the operations and holdings of these large companies. Several of the concerns, through their posi- tion as regular marketers, also exercise a strong control over the opera- tions of many others. The responsibility of the large concerns for the care and protection of our oil fields is, therefore, obvious, and the depart- ment has given particular attention to seeing that they adopted and fol- lowed the most approved methods. It should be clearly and unmistak- ably understood that in the past some of the largest operators have also been the most careless and wasteful. That condition is now being remedied, but the task is not yet completed.^ The proportion of water and oil produced by certain concerns in the various fields of the state is shown by the accompanying diagram.

The money received from collection of the a.s.ses:>;ment comprises the I)ctroleuiii and gas fund and is used for the support of the Petroleum Dei)artment of the State ^Mining Bureau, and for the repair of oil wells. The rates, sliown on the accompanying statement and used in determin- ing the various items, are determined in accordance with sections 23, 24. 25, 27. 46 and 47 of the said statute. The detailed method is as follows: Tlie amount of money to be raised annually, as provided in section 27. is sufificient to maintain the petroleum and gas fund at an amount not exceeding one hundred fifty thousand dollars. The amount this year is one hundred twenty-eight thcmsand three hundred sevent^'-five dollars. One-tenth of the above mentioned .sum of one hundred twenty-eight thousand three hundred seventy-five dollars is levied upon the oil land of the state. The remaining nine-tenths is levied upon the oil produced and the gas produced and sold. For the purpose of this assessment ten thousand cubic feet of ga.s is considered equal to one barrel of oil. The amounti> of land, oil and gas and the nnm])er of producing wells in the various counties were determined to be as follows : Fresno Kern l/os .\neeles Orange Ventura Santa Barbara . San Liii.s 01)is]io. Santa Clara Totals Fxpeiulilure in repairing wells is to be repaid by satisfaction of a lien upon the property where tlie work is done.

By comparing the foregoing figures with those covering the previons year^ the increase of routine field work and the advance in our engineer- ing investigations are clearly seen. The amount of routine work of the various kinds increased from 8 to 74- per cent due to increased activity iu all the oil fields. The greatest increase is noted in the number of tests witnessed, which reflects the closer touch we have been able to maintain with actual field operations. The progress of investigations, which must underlie all intelligent decisions, is indicated by the number of graphic logs and the total area covered by peg models. The number of producing wells for whicli graphic logs have been made is now 82 per cent as against 36 per cent for the previous year. The acreage of proved land for which peg models have been completed is now 42 per cent as against 15 per cent last year. LOS ANGELES AND ORANGE COUNTIES. Operations in Los Angeles and Orange counties have been followed with particular interest during the year because it is principally through the new production from the IMontebello and Coyote Hills fields that an otherwise declining state production has been maintained. The report of M. J. Kirwan shows that the oil production of the two counties increased 28.236 barrels per day between June, 1917, and June, 1918. This increase, however, does not represent the total amount of oil con- tributed by the 76 wells completed during the year, because there was a decline of 11,060 barrels in the production of wells completed before June, 1917. The total average daily production contributed by wells completed during the fiscal year was, therefore, 39,296 barrels. This production came mostly from the Coyote Hills and Montebello fields. These new wells have more than doubled the production from all wells in the two counties. Although there have been serious water conditions to deal with in recently developed areas, Mr. Kirwan 's rei)ort shows that the wells completed during the year produced 5.5 per cent water, as compared with 21.6 per cent water for production from all wells completed prior to June, 1917. As shown iu the report, three wells, in as many fields, contributed more than half the water for tli(^ new wells in those fields. Even including these three wells, for which no responsibility can be assumed by this department, a comparison of water percentages for the old and new production demonstrates the value of properly directed engineering work. Repair work has been started on two of these wells. The third well, situated in the Montel)ello field, is not onl>- a menace to 'Bull. No. 82, Cal. State Min. Bur. p. 121. THIRD AXNLAL REPORT. 57 this new field, but is a serious reflection against operating methods of one of the largest producers in the state. The amount of work in the two counties, involved in reconiinendations and engineering advice to operators, has more than doubled during the past fiscal year. The department has been steadily engaged in the work of assembling all available data on past and present oil well operations as a ground work for future engineering problems and investigations. Graphic logs have been made of 94 per cent of all logs on file. Uni- formly drawn graphic logs have been necessary in the construction of peg models for study of underground conditions. Peg models have now been constructed for most of the important areas in Los Angeles and Orange counties. Numerous operators have made use of the models in preparing estimates for drilling programs. Mr. Kirwan's report shows tliat there were only two formal com- plaints filed during the year. One of these complaints was settled in accordance with specifications issued by this department. Settlement of the otlier complaint awaits developments at a well now drilling. The Coyote Hills field added 28 new v.ells to the list of producers during the year. These welLs show a high daily average of production and are free from water. A study of underground conditions, iiiade by this department, shows that even the proved portion of the field has not been developed to the full extent of its possibilities. Mr. Kirwan's statement of the conditions under which Murphy-Coyote Avell No, 44 of the Standard Oil Company was drilled, in accordance with recommenda- tions of this department, illustrates the benefits of engineering study and application. An oil-bearing zone, previously considered nonproductive, was developed. The production, in itself, should be sufficient to bring a profitable return on the investment. Any operator can profitably afford to follow such methods in deter- mining the nature and numbei- of oil-bearing formations or zones wlii-li underlie his property. It is somewhat surprising, in view of the demon- stration made at the well referred to. that the company has made no further effort to test the zone. Anything but the development and con- servation of the resources of a property to the extent of its cconomii- possibilities is a shortsighted policy on the part of any operator — large or small. Thirteen wells were completed in the Olinda field dui-ing tlie fiscal year. Most of the development work was carried on by the I'nion (^il Company and Petroleum Development Company. A change, by one company in this field, in the method of reporting water produced, shows that the method, quite common througliout the state, of reporting only water in suspension after free water is drained off, gives a .statement short of the facts as to the water condition of the "58 STATE OIL AND GAS SUPERVISOR. well. Due to the pressure of work iueident to the drilling and repair of wells, the matter of submitting accurate reports of water and oil pro- duced has not received the attention that it should have received. In analyzing operations in any group of Avells, it is just as essential to have accurate records of production a,s it is to have accurate logs. Large quantities of free water drained from tanks and sumps are frequently not included in the operator's statement of fluid produced by a well. As the work of assembling records and preparing engineering information on underground conditions approaches completion, more attention will be given to this important accounting phase of the work. A study of underground ccmditions by engineers of the Petroleum Development Company in this field has already yielded a substantial increase in production and opened the way for further profitable development. There were no important new developments in the Brea Canon field during the year. Mr. Kirwan has indicated that there are two groups of wells in this field responsible for almost 90 per cent of the water pro- duced in the entire field. The method of repairing one of the wells of the Birch Oil Company, according to specifications issued by this depart- ment, demonstrates the possibility of benefiting the general productive condition of the field through plugging off water and also perforating opposite oil sands heretofore excluded. There was a small decrease in production in the Puente field during the year. The production shoAvs only a small percentage of water. A slight addition was made to the proved acreage in the Whittier field. Production records of this field, as to oil and water, show the necessity of certain repair work on old wells. It is also evident that a larger drilling campaign is necessary in order to maintain production. The advantages of careful prospecting and testing by zones in this field, are i)ointed out by Mr. Kirwan. giving definite results obtained at a number of wells. Ilis report on the Murphy- AVhittier property of the Standard Oil Company gives a thorough analysis of operating condi- tions in the Whittier field. The report can well serve as a model for other engineers. There are several productive zones in this field. In order to conserve casing, and at the some time protect upper zones, in deep wells, this department has recommended the use of mud-laden fluid. Tlic use t f mud. however, is prescribed for certain definite purposes. It is still necessary for some operators to familiarize themselves with details of the mechanical operations involved in the proper use of the mud-fluid method. As already st.ited, the ?kroiiteb('ll() field has played a very im|)ortant part, during tlie past year, in maintaining the production of the state. THIRD ANNUAL REPOR'l . 59 In June, 1917, this field was producing 852 barrels of oil per day, and in June, 1918, the production had risen to 16,985 barrels per day. Nearly three-fourths of the present production is from wells of the Standard Oil Company, which drilled the first producing well in the field. Present indications are that water is going to prove a serious obstacle in the development of the field. In view of the fact that this depart- ment has prepared a complete analysis of underground conditions from present available data, for the guidance of operators, it is obvious that the responsibility for the future of this field rests largely upon the operators themselves. The Standard Oil Company has an opportunity to demonstrate whether or not a large operating concern could efficiently protect the oil lands developed by it. It has long been recognized that one of the most important factors in the protection of any field is stratigraphic uniformity in depths of shutting off water. The Montebello field is not an exception to this condition. Failure to determine accurately the position and productive- ness of oil-bearing formations prevents the planning of these necessary uniform operations to control water and obtain maximum production. In view of these conditions, this department has recommended careful testing of formations during drilling. The results as shown by the drill, and reported by the drillers, are the basis of all engineering .study of underground conditions. Nearly nine thousand logs of oil wells on file with this department, the records of drillers' observations, bear sufficient witness to the degree of respon- sibility of the man who drills the well. In this connection the following testimony, given by certain drillers, with reference to their observa- tions during the drilling of well No. 4, Baldwin, of the Red Star Petro- leum Company, in the ^NFoutebello field, which, as stated by Mr. Kirwan in his report, was the subject of legal action, is deemed by this depart- ment as ample and sufficient evidence in the course pursued: STATEMENT OF H.

W^hat instructions, if any. did you receive in regard to making up the log book on this particular well ? You receive any par- ticular instructions any different for this well than for any others ? A. He told me that morning he wanted that mud kept as heavy as possible, and he said that Kirwan wanted to save out samples every ten feet, but he did not tell m(^ where or when to start. Q. Did he ever at any time tell you not to take samples ? A. No. he did not tell me not to. Q. Never did instruct vou at anv lime to tak(> samples? A. No. THIRD ANN UMj KEPORT. 61 Q.

Yes, sir. Q. How hmg did you work with that thick mud? A. All the time. Q. During what depth, about? A. I think he told us to keep the mud tliick from 1;M() Feet, oi' something like that. Q. You kept the mud thick from that time on did you? A. Yes, sir. Q. How deep did vou uo in this well? A. 1512, I think. ' Q. NoAV, did you see any indications of oil dui"ing tliat distance? A. I certainly did. Q. AVhere did vou first notice it? A. About 13'9f)'. Q. What kind of shale were you in at that time? A. We were in sandy shale. Q. You ever report that to ^Ir. Lloyd? A. No, I did not. Q. Did he ever say anything to you about any oil indications? A. Yes, sir, he did. Q. When was that? What particular depth, do you remember? A. Along about 1350. 1 think he said. Remark by Mr. Glover: Now, i\Ir. Kirwan, I think if you will go ahead from here, if there are any points you particularly desire to bring out ? Questions by Mr. Kirwan : Q. What evidence of oil did you have when you first noticed the oil? A. Saw it around the ditch. The scum came up from the ditch when I first noticed it. That is the only way you can tell. Q. When vou pulbnl out the tools was there any sandy shale on the tools? A. Yes, sir. Q. Did that sandy shale have any evidence of oil in it? A. I broke a piece open and oil sand inside of it. I laid it upon the bull wheels and Mr. Sprague saw it. Q. How large a sample of oil sand was in that j^articular piece of shale ? A. I should think about as big as your thumb, aiul smelled strong, too, Q. You actually saw the oil oozing out of the shale tliat you broke. open? A. I did. Q.

Was there any shale brought up by the bit that .showed any evi- dence of oil during the drilling between those depths? A. There was. because I pulled out, and I found a piece of shale on the bit that indicated oil. Q. That depth you pulled out was bottom, 1496? A. Yes, sir. Q. Did you .save that sample of shale ? A. I am not sure. Q. Did you ever save any samples of this well or turn them over to anybody that you remember of? A. No. " Q. Who else worked on the well in addition to yourself, who were your helpers?

Was there any discussion among the men as to the evidence of oil in this sample from the rotary bit ? A. Well. I broke it open and showed it to them. I don't know whether anv of them smelled it or not. I think Mr. Sinclair did. Q. Did they make any remarks to you whether it was a good show- ing or a poor showing? A. He thought it was a good showing on the bit. Q. AVho in particular made that statement, and, if you remember, what statement did he make? A. I think Jones was out there, the derrick man, and he said he thought it a good .showing of oil. Q. That was at a depth of about 1396? A. Yes, sir. Q.

When did vou quit workins; for them ? The 24th of June, 1918. What well were vou working on at that time? Red Star No. 4. Who else was working en the well at the same time? Mr. Sanborn and ^\r. Sprague. During your tour who was assisting you? My h('lper.s were Clayton Jordan. Frank Vaegei-, Paul Hobiu.son, and a fellow by the name of Charlie Jacobs. Who did you work under, who wa.s your foreman ? Tom Lloyd. Did you receive any instructions directly from him .' Not always directly from him, no sir. In case he was not on your tour at any time, how did you get your orders ? A. I generally got my ord(>rs from the driHer I relieved. He would leave word with this driller what he wanted me to do. or what action he wanted me to take and this driller would tell me. Q. What driller did you always relieve? A. I always relieved Mr. Sprague on this particular well. Q. Did you ever get any in.structions from .Mr. Lloyd or Mr. Sprague in regard to making up the log or report on this well? A. No, sir. 64 STATE Olli AND GAS SUPERVTSOR. Q. Did yoii cvci" sec any indiention of nil. sny fj-oin tlic depth of l:ii)() feel on down? A. Yes, sir. Q. AVhat Avere the indications? A. The indications were on the ditch as to oil floatino' on the surface of the ditch, on the top of the mud. oil and ga.s showing both. Q. Whose tour vras it that this oil wa.s first discovered on, if you know ? A. I don't know what tour it was first discovered on — I think it was first discovered on ^Fr. Sanborn's tour. (.^. When did you first learn thft there had been any oil discovered by anyone ? A. You mean what date, cr what dep'th, or both? Q. What depth? A. As well a.s I remember, it was about 1456 — that w^as the depth at the time I heard abont the oil being seen on the night l^efore. ]\Ir. Sanborn told me about it. Q. You remember what he said to you at that time? A. Pie made the remark that he got a piece of shale of¥ of the bit the previous night w^hen he pulled out. and that there was quite a nice show'ing of oil seen in this shale. Q. Did yon make any report in your log of this oil? A. I did not. Q. Why didn't you? A. I did not think such a report was wanted. Mr. Lloyd has always given me to understand that he did not want any oil showing, to show- on the ditch, so I naturally supposed from that he did not want it to go in on the log. Q. You .say he had given you to understand, what do you mean by that? What made you think he did not want any showing? A. He told me that he didn't. Q. What did he say ? A. He said that he w^anted me to carry the mud heavy and prevent any showing of oil or gas if we possibly could; that the water commission w-as watching that well pretty close, and the}' did not want it to show up at all. Q. You remember what date he told you this? A. I don't remember the date. It was when w^e Avere around 1300 or 1350, or something like that. Q. Therefore you never made any report of any oil or gas? A. No, sir. Q. Was ^Ir. Lloyd ever present when there was any showing of gas on the bit? A. Not on my particular tour, no. Q. Ever any discussion on your tour between you and your helpers as to any oil .shoAving? A. There Avas on the next to the last tour that I run. Mr. Jordan Avent out on the ditch and discoA'ered Cjuite a shoAving of oil and gas, and in holding his hand on the ditch his hand Avould become covered Avith oil, and he would catch quite a fcAv particles of oil sand in his hand.

II<^ earae into the ri^- where I was and made the remark that we had a fine showing of oil there and he lield his hand up and showed me where it was all covered witli oil from dipping it into the ditch. Q. You made out a report of that run did you, after that? A. I made out a report of that run. I did not report the oil. Q. For the same reason that you have already stated? A. Ves. sir, because I did not suppose thev cared to have anv report of it. Q. Had you ever received any instructions from the company at any time, either directl}' or indirectly, not to report these showings? A. Well I had indirectly, yes, sir, not on this well, but on the former well that I worked on. Q. What well was that? A. The Tri-City well. Q. Who did vou receive the instructions from at tliat time? A. E. L. Smith. Q. Who w'as E. L. Smith, and what authority did he have? A. I don't know that he had any authority, he was the driller that I relieved. He was drilling the tour from eight to four, and I asked him whether or not they reported oil and gas showings, and told him that I had had a slight showing of oil and gas on this well, and he said no, they did not generally report it, because they had got into several mix-ups by reporting it, and they did not do so now, making no report on the log. That is all the orders I had at any time as to whetlier to report them or not to report them. Q. And you were working for the same company at that time? A. Xo. that Avas the Pan-American Petroleum — it was under the same management. Q. You say that you arc not in tlie employ of the company at the present time? A. Xo, sir. Q. Wlien did you quit? A. Discluirged on the 25th of June. (^. And wliy were you discharged? A. All the reason I could get for being discharged wa.s l)ecause I had not taken any samples on this Red Star 4. I had never received any orders to take samples. Mr. Lloyd admitted as nuich to me. Q. You say "admitted" — that might be conclusive. AVhat did he sav 9 A. I don't know that I could say word for word. I asked him whether or not he had issued me any orders. He said tio. he issued them to Harry and to Johnnie. Q. You never received any orders from Johnnie or Hai-ry ? A. The nearest to an order that I received. Mr. Sprague told me we were going to have to save samples every ten feet, but I do not recall that he .said where or when. ()G STA'I'K Oil. AN'!) (;\S sri'KiniS( )K'. <^.

Harrv Sianborn and Johnnie Sprague. Q. You know R. L. Peeler? A. Yes, sir. Q. By whom was he employed? A. I guess he was employed by th-.' same outfit that I was. Q. Did you see him at any time there at the well on your tour? A. Once, yes, sir. Q. When was that, do you know? A. I think it was in the neighborhood of 1400 feet. I don't know the exact depth. Q. Have any conversation with him in regard to any oil sliowing? A. I talked witli him. but there was nothing said al)out the oil showing. Q. What was the conversation ? A. I asked him whether or not th(^\' had discovered any oil in the Tri-C'itv well. Q. Wlmt did he say? A. That they had not. Q. Did you ever have any instructions or orders to work in connec- tion with him in regard to the oil? A. No, sir. Q. Or any indications that you found of oil there? A. No, sir. Q. What were his particular duties at the well, do you know? A. I don't know. My understanding was that he was supposed to be a geologist for this company. That was simply through hearing the other drillers talk. They called him the "mud smeller." I don't know what his official capacity was. Q. Did he ever at any time ask you in regard to any indications you found on this well? A. No, sir. Q. Now you were on tour at 1436 ? A. I went on tour when the well was that depth, >'es. sii*. Q. How far did you drill ? A. Twenty feet, to 1455. Q. During that tour did you see any indications of oil? A. Why, yes, there were indications of oil in the last two tours that I run there. Q. What particular indications were there between 143(i and 1456, if you remember? A. The same indications that I formerly stated. Oil on the surface of the ditch and gas showing. Q. Did you have any instructions in regard to the thickness of the mud. how it was to run? A. Yes, sir. Q. Who did von get vour instructii)iis from in reyard to thai .* A. Mr. Llovd. TlTlRn AXXr.VI.

And you did keep the mud thick? A. I did for a while, and it was so thick I could not make any progress witli the bit. so I thinned it up. and Mr. Lloyd the next day sent word througli Mr. Spi-aguc for me to keep the mud thick, not to thin it. Q. AMien you thickened th(> nnid up. it retards drilling consider- ably, doesn 't it ? A. Ye.s. sir, it does, in shale digging it does. Q. And in following the orders received by you. therefore, you would considerably retard drilling operations? A. Yes. sir. in the particular digging I was in at the time, it would Q. In drilling a well in shale of that nature, is there any necessity for making the nuul thick in order to prevent caving, or any- thing of that kind? A. Absolutely not. it will make nuul thicker than you can pump it out In- digging in it. Q. Is there any necessity at any time in drilling to keep the nuul thick in this particular w^ell? A. Not from the depth that I took it on down. I found no occasion where it would be necessary. The well never showed any signs of doing anything but standing up to the best of shape all the time that I was on it. Q. What depth were you when you started drilling this well? A. As near as I rememlier, we were about 600 feet. Q. And the formation was such it would stand up in good shape from that on down, was it ? A. Yes, sir. I did not pass through anything that would not stand up in good shape. Q. You never had any trouble with caving at any time, and no occasion to thicken the mud to prevent caving? A. No. I think as good proof as you could get is the fact that w'c twisted ot¥ iK'fore we thickened this mud and it .sat there for 12 liours. Q. IIow deep was the hole then ? A. As near as I remember it was in the neighborhood of 1000 feet, and if the well was caving at that time we would have had difficulty in pulling this pipe out after we got hold of it, after it sat there for twelve hours. Q. And the mud was ruiuiing thin at this time? A. Yes, sir, the mud was in pretty good shape then. Q. Just what do von mean when voii u.se the expression "twisted off." A. Just exactly what I said — the pipe twists in two. Q. When you were ordered by Mr. Lloyd to thicken the mud to prevent oil showing, was any reason 'jiven to you wliy the oil showing was undesiral)le? A. Yes, sir. Q. What was that reason? A. The rea.son he gave me was that the water commission was watch- ing this well pretty clo.sely. and th.'y did not want the water G8 STATF OIK AXn GAS srPKKVISOR. coiiiinissioii to sec ;iiiy oil sliowintr on the ditch. They wanted it to j^o throuijh lliis sand witliout liavin^ to stop there. Q. You were discharged from this well on what date, Mr. Thompson? A. The 25th. Q. At what time? A. Four o'clock in the afternoon. Q. Who told yon that yon were discharged? A. T. E. Lloyd. He did not tell me I was fired. I a.sked him whether I was fired, or what was the matter. He said no, I don't want to fire any of yon boys for the simple fact that yon might at some time want to work for this company again, either here in the Ignited States or in Mexico, and he said that if the records showed that we were fired, it would be a difficult thing for us to obtain a position, "'but" he says, "I advised the other two boys to quit, and told them where I thought they might get a .job." and when I asked him what his idea was in letting us out he said it was because we had not saved out sam- ples, and that he felt no other man could put us on any other well and get by with it. I asked him then if the water eom- mi.ssion was running this oufpl, and he said they were ju-etty near it. Remark by Mr. McLaughlin: Q. He told you you were fired because you did not keep samples? A. Yes. sir. Q. Were you told by ^Ir. Lloyd that the state officers had been influential in having you discharged? A. Xo. I can not say that I was told by him that you were. He left me. and I think the other boys, under that impression that it was through the state commission that we Avere going to be discharged. That was my understanding of it. Remark by ^NIr. Glover : Q. Had you seen anything of ^Ir. Kirwan or the commissioners the day you were fired? A. Xo, sir, I asked to see them, they were at the office at the time, and I asked to see the commissioner who was the cause of it, and ]Mr. Lloyd said he was being made the goat of. and he was the man that was having to do the discharging. Q. That is, you mean they were at the office of the Red Star Com- pany at that time ? A. Yes, sir. Q. But you did not have any conversation with the .state officers at at that time ? A. X"o. sir. Q. Xeither one of them ever setul any word to you men while you were employed on the well? A. X"o, sir. Remarks by Mr. ^IcLaughlin: (^. Did Mr. Lloyd ever tell yon that the company had had any tron- ble at any other well with the state officers? A. Yes. sir, he mentioned two other wells, if I remember right — T think one was the Darlington, and the other was the F*ruuh one. TUIKL) AXXr.Vlv KEl'ORT. 69 Q.

Yes, sir, he said that the company was beatinjjj the case on one of these other wells — I forget which one he said — but that owing to tlie fact that tlie water connnission was losing out in the other suit it would be particularly anxious to catch us up on this Red Star 4. and that was his reason for having the mud so thick that the oil would not sliow up, so to avoid you people being able to catch them up on this Avell.

THIRD ANNUAL REPORT. 73 IMr. Kirwan's analysis of conditions in the ^Montebollo fi(»]d and his- tory of development should have the earefnl study of all operators interested in the developnu'nt of tliis tield. He notes that, with few exceptions, water was shut off above the tii-st oil-beariuu' formations penetrated. VENTURA COUNTY. Increased activitx' in tliis county and expectation of still further increase of oil ])rodnetion caused the department to establish an office at Santa Paula durintr the ]")ast year. It will be noted that our preliminary engineering' work' has been carried well along' towards completion, notwithstanding the fact that the tields ar(» small and widely se})arated. The county appears to offer further o])i)ni'tunities for new develop- ments and the .small size of the fields may specially attract small opera- tors. Some of the tields. particularly Pirn, Ojai, and Ventura, are pro- ducing water in such ([uantities as to reduce profits to the operators. Developments in the field near the town of Ventura are extremely promising, but water conditions are a most seriou.s obstacle. The depart- Hient has had some difficulty in impres.sing the necessity for systematic work, and there are wells which now menace the field. However, the fact is now more generally recognized that the Avater absolutely must be controlled if the field is to become a profitable producer, and better work may be expected in the future. In this field the department has made a special effort to rely on advisory supervision on account of the fact but little is yet known of underground conditions. The construction of peg models by the department has been responsible for the discovery of many underground conditions which were not previously known. This information has already been of immediate assi.stance to operators in several instances and will be of still greater value in the future. Descriptions of the various fields by Mr. Augur set forth some of these details which merit the' careful attention of inter- ested parties particularly on the JMontebello dome. The completion of shallow i)roductive wells neai- the \'entui-;i River, st'vei'al miles west of Sulphur Mountnin, is an examph.' of the fact that old [prospecting work has not fully developed the county, and that detailed gef)logical studies will be profitable. SANTA BARBARA AND SAN LUIS OBISPO COUNTIES. The underlying engineei-ing woi'k for the Santa Maria, rasmalia. Cat Canyon, and Lompoc fields has reached far along towards the point where systematic repaii-s and develoi)miMit can i)roeeed. About SO per cent of the ])i'()Ved acreage is now covered by peg luodels. 74 STATE Oil; AND (JAS SUPERVISOR. When the department, entered these fields three years ago it was lx)und that, althoujih the tields had been operating .some ten years, prae- tieall}' no detailed and .systematic study had been made of the under- ground conditions. In view of the fact that the major i)ortion of the "old field" is under control of the Union Oil Company of California, and that water production is far above the limit found justifiable by other operators in the state, it would seem reasonable to expect that the company will soon adopt modern methods of coping with an unprofit- able .situation. The operators in the new Casmalia field have already started on such a course. In general a hearty .spirit of co-operation has maintained between the operators of these fields and the department. It is worthy of note that large sums of money have been expended on wildcat operations which might reasonably have been avoided. A substantial increase in production from the small Arroyo Grande field occurred during the year. New operations in the Ca.smalia field are among the prominent features of the year's work. It will be seen, in Mr. Bell's detailed report, that water conditions are serious and that the department has taken active steps in guiding development and repair work which has recently been undertaken by the operators. Another year should show profitable results providing the operators continue systematic and co-operative efforts. This locality is an excellent example of the fact that even the latest and most approved mechanical methods of shutting off water avail but little unless guided by geological and engineering study. The detailed report on these conditions should prove valuable to progressive operators in other fields. The Cat Canyon field progres.sed but little during the past year, and adverse water conditions were encountered. Recent developments in this locality are an example of results following scant u.se of geological and engineering knowledge. It will be noted that pos.sibilities of future profitable development still exist. The Lompoc field saw no new development during the past year, although there appears to be ample margin for new wells in the proved area. The field i.s controlled by the Union Oil Company of California. Water is not being properly excluded from the oil-bearing formations. In the Santa ^NFaria field proper, sometimes referred to as the "old field,'' important results have followed the drilling of the second zone of oil-bearing formations. The new second zone production is thu.s far free from water and geological conditions are so favorable that only reasonal)le care would .seem necessary to preserve the present status. This is an important discovery in view of the fact that flooding of this zone at various other places led to the assumption that it was irreparably ruined. THIRD ANNUAL REPORT. 75 New drilling into tiie tliird zone has developed the fact that an "inter- mediate" water-bearing formation exists. Previous failure to identify the nature and position of this water-bearing formation possibly accounts for much trouble developed in the past. Extreme care will be necessary in future work. The Sargent field, in Santa Clara County, is the farthest north of all l)roducing fields of the .state. The field i.s small. One new well was drilled during the year. KERN COUNTY. The Kern County oil field operations constitute the major portion of the activities of the state. When the department entered these fields three years ago it found some of the most aggravated water troubles existing in California. It also foimd that little or no systematic and detailed study of underground conditions had ev^r been made. The present report shows the degree to which the necessary funda- mental investigations have been pursued. Graphic logs for about 75 per cent of the producing wells have been made, as against 26 per cent a year ago. Peg models now cover 23 per cent of the proved area as com- pared with 12 per cent last year. But few completed reports on fiooded areas have been made, as shown by ^Ir. Ferguson's report, due to the fact that we had to first gather all the underlying facts. The next year will undoul)t(Hlly furnish a number of completed reports with conclusions and recommendations for repairs and developments. Routine field work increased in all branches except that due to new welLs. The largest increase was in the witnessing of tests, which amounted to 60 per cent. Special tests to the number of 161 were witnessed. These tests cover such operations as plugging and mudding new wells and were witnessed for the purpose of affording the utmo.st security possible. It is probable that, even with this extra effort, many operations were completed in a manner not up to the best practice developed and proved in other localities. Pressure of work has pre- vented summarizing the results obtained from unusual operations such as mudding^ and we are, therefore, not yet prepared to make definite statements as to the efficacy of the process. In the case where the supervisor's order was reversed by the district commissioners (p. 413) .subsequent developments indicate that the con- clusions of the order were correct-. Aside from damage and lo.ss. at the particular locality involved, it is hoped that this case will demonstrate that an operator's own interest will best be served by entrusting engi- neering i)robl('ms to an engiiicci-inu oi-jianization rather tiian to a legal .staff.

The Suuset field presents some of the most complicated iiiidergrouud conditions existing in California. The field has in recent years also witnessed some of the most ill-advised development operations which will require extensive revision and repair. The Belridge field has, during the past year, furnished an excellent example of the value of careful and systematic prospecting work. While the Kern River field has not yet seen very extensive repairing of its extensive and widely known water troubles, it is worthy of special note that the largest operator has undertaken detailed engineering inves- tigation. This department has continually urged such proceedure. In the Midway and ]\IcKittrick fields it will be noted, 1)\- Mr. Ferguson's report, that the number of complaints filed l)y the operators has fallen off. On the other hand, joint requests for investigation have been filed. As previously stated this department can not nuike recom- mendations until all the facts are assembled. FRESNO COUNTY. The operators in the Coalinga field were the first in tlie state to recognize the necessity of systematically drilling and repairing wells so as to avoid water trouble and secure the utmost production.^ The result of the earh' use of methods now followed and enlarged by tliis department is shown by the relatively small amount of water no\v' handled. An understanding, on the part of the most of the Coalinga operators, of the value of engineering Avork, has made it possible for the department to readily co-operate with them in the manner referred to in Mr. Bush's report. It has also been possible to prove or disprove many assumptions as to underground conditions w^hich are of general economic importance in planning the operations of any oil field. The oil industry must look forward to the necessity of jnitting forth every effort to determine the existence of loss either of time, labor, or material, so that such loss can be reduced. It will be noted that our report covering the Coalinga field this year summarizes the amount of time lost due to idleness of completed wells. It is believed that no such figures have ever before been assembled and as the system may be per- fected throughout the state, a basis of comparison may be established. In view of the fact that from 10 to 20 per cent of the possible ])inuping time is being lost it will be seen that the item is imporant. The individual instances cited by ^Ir. Bush show that even in a beld where systematic principles are extensively applied new problems are constantly arising for careful study and supervision. ■Bull. No. T;;. Cal. Stiite Min. Bur. p. 30.

The meeting was called by the California State Mining Bureau and was attended by representatives of the Mining Bureau and various California oil companies. ]\rr.

State Oil and (Jas Supervisor: Centlemen : As the announcement has been made, this meeting is particularly to discuss the po.ssibilities of the use of miul. It is unnecessary to call to your attention at this time that casing is not the most plentiful thing in the worhl. This subject of u.sing mud came to our attention shortly after tile (li'partment was organized and we immediately took it up and made some investigations Avhich your attention was called to in our first report. A number of operators, we thought, would see the possibilities of the thing. We were disappointed in that — in fact there has been only a few operators who have undertaken to carry on an experiment and an experiment of any kind must be carried on under conditions which we control so that you can draw conclusions when you got through. We proposed that a certain number of wells should be drilled in clean ter- ritory and then give time to see whether or not this mud shut otf was eflfective. Now. we have been i)articularly fortunate in having the co-operation of the Shell Company in the Coalinga field, which has drilled some wells, and their geologist. ^Ir. Nolan, in conjunction with .Mr. Busli, of this department, have sunnnarized descriptions of tliis work and Mr. Nolan has kindly consented to read the results of that w(,rk. After he lias read these results, the nuitter will be taken up for discussion. DEMONSTRATED VALUE OF MUD FLUID IN PROTECTING OIL SANDS. By 10. IJ. Xoi.AX. Shell ( "onipanv- of Calit'oniia. By means of a test w<'ll in Section 27, T. 19 S., R. 15 E., of the East- side Held at Coalinga, the Shell Comi)any has proven thus far that rotai-y drilling effectively seals up oil and water sands. Tn this portion of the field then' are the usual toj) water sands with large vohnne and considerable head, then below them upper oil sands then an intermediate water and finally the I'ieh lower oil sands.

From these wells they dedneed the following: jreneral conditions: 1. No conductor pipe is needed as it is not necessary to put on addi- tional head over the hydraulic head of the fluid. 2. Hole is mudded almost instantly as rotary passes them. Fast drilling and rapid circulation are the means of accomplishing this. 3. Rapid rotation is conducive to effective mudding by contact with sides of hole and conseciuent tendency to force mud into the formations and by causing the solid particles to seek the side of the hole due to the centrifugal force. 4. We circulate the hole from one to three days after the proper depth has been reached. However, we have found that at this stage some holes will take no mud at all. some will take a little, and that none of them will take any mud after twenty-four hours. 5. Circidation can only be regained within Hiiee or four hours, and casing will freexe tight in this ti)m-. This we bi'lieve sliows a distinct settlement aiid tendency of the mud to solidify. G. The casing is cemented with 2()(/ or more sacks 1)y the Perkiiis ino- cess. This should force cement abov? the top of the highest oil sands. 7. Cement will set fairly hard even when mixed with 50 per cent mud and a mixture up to 80 per cent affects the strength very little. This we know from a number of laboratory tests. We therefore need have no feai- of the cement not setting in a rotary hole. 8. A number of gravity and viscosity tests have been made on the drilling mud used on these wells. The muds range from 5 to 10 per cent heavier than water. The 10 per cent mud is about a.s heavy as can be used for drilling. The viscosity of the muds from blue clay of the above weights range from 2.3 to 3.5. These viscosities were ol)tained in a regular P'ngler viscosometer. Mud from red clay seems to have a lower viscosity for the same weight. Centrifuge tests show the mud to range 2 to i prr cent sand and 5 to S per cent solid day. These samples are taken from the mud pit after settling, when it is ready to be pumped back into the w-ell. Only a few samples have been taken of mud as it comes from the well, but these show consid(M-ably more sand: some as high as 13 per cent. These tests indicate that the seltliim canal does the work expected of it. CONCLUSIONS. Hy U. 1). Bush, California Slat"- Mininj; Hmvaii.

Of Ihe wells eemented aJ)ove the? upper zone, some were drilled entirely throuiili the lower zone and did not encounter the intermediate water, indicating- that the water probably occurs in lenses of sand. The character of the oil sands in this part of the field is such that water does not readily travel through them. The oil is comparatively light in gravity, about 20 degrees. The oil sands are hard and compact as shown in the drilling and by the fact that the wells produce very little sand, if any. Wells in this part of the Coalinga field have been known to stand or be in the process of redrilling or plugging with a large head of water on the oil sands for two and three years without affecting pro- ducing welLs 300' and 400' aM^ay. For this reason it is the writer's opinion that it w'ould be necessary to change the specifications of the mudding process used by the Shell Company in order to meet different conditions in other parts of the ('oalinga field and in other fields of the state, where sands are more porous, or there is artesian water, or high pressure oil and gas to contend with. Mr. Nolan: I might say, in this connection, that the Shell Company has recently abandoned two different wells by the mudding process in this portion of the field and another one. No. 14 in Section 14, which is in the north end of the east-side field. This well, No. 14, took a great amount of mud, over 40 tons and all under pressure of less than 200 lbs., in 80 ft. sand, and, in fact, mud appeared in a well 400 ft. away in three days after mud was forced in ; although under practically nothing but the hydraulic pressure of the mud. This shows that the sand up there is certainly very porous. On the other hand, Well No. 62, Sec. 27, abandoned in this portion of the field in 500' of sand and shale, after the well produced for about 5 or 6 years, took a very small amount of mud, although the pressure went up to about 200 lbs. This would cer- tainly seem to check up the investigations made by the State Mining Bureau.. Mr. ^IcLaughlin : Gentlemen: That sums up the facts of the case. In order to forestall any misunderstanding, I want to particularly call attention to the fact that the conditions in that part of the state are not exactly the same as they are in some other portions even of the Coalinga field and that that is a demonstration of the success in one particular locality. The idea of the meeting is to have a discussion of these papers as we go along and anyone who has any question to ask of Mr. Nolan or Mr. Bush, nuiy do so. Mr. Pollard: It seems to me that the first thinu' we ought to discuss and ascertain and have everybody understand, would be the action of the mud-fluid in a well. For the first time since I have been handling the TMIRn ANNUAIi REPORT. 81 iniul-liuid for tlie purpose dcserihod here this inoruinj?, have I ever heard as clear and eoneise an idea of what the nuid-tluid did in a well as Mr. Nolan of the Shell Company read this morning, but yet I feel that the majority of the drillers and operators are still in the dark as to the real action of the mud-flnid in tlie ground, and I know, through having had experience in traveling over the entire United States and in the employ of the Federal Government, that it is not understood, and I believe that, as a starting point and to get the men to understand where we are, we ought to first of all discuss what the action of the fluid is in the ground. This, as I say, has been somewhat clear in the paper just read, but yet it is not clear to those who have not made a deep study of this question, and it is one of the most vital questions that there is, in my opinion, in the petroleum industry, and I feel I would like some of the bureau men to tell us what their opinion is as to the action of the mud-fluid in certain territory toward the walling up and the prohibiting of one formation contaminating and mixing with the other, and I believe that a discussion along that line, first of all, would enable us to get a clearer and more concise idea of what we have met here for this morning. ]\Ir. McLaughlin : I think that these suggestions of "Sir. Pollard's are very apt. I will put forth some idea of the elementary principles of this and I hope Mr. Pollard will correct me on any point. The theory of the mud-laden fluid is that the water is carrying in suspension fine mud entirely free from sand. Filtei*s in cyanide plants at gold mines, for instance, are of canvas, and there is a vacuum created on one side which causes the liquids to go through the canvas and strains the slime out and deposits it on the canvas. When this cake is built up to the extent of about three-quarters of an inch, the filter becomes impervious and they have to clean that canvas off by reversing the current of air and blow the slime off. It is reasonable to assume that, when mud or mud- laden fluid, slime, is passing through a sand, whether it is a water or oil bearing sand or anything that has an opening, that the clay will be deposited the same as it is under all conditions that we have observed; therefore, the clay would be forced out from a well to a considerable distance, sometimes greater, sometimes less. Now it is well to bear in mind that it is a different action that you will have when mudding up a well with a rotary. Now bearing in mind how a filter is actually observed to close, I think you will get a conception of wiuit the mud- laden fluid is. I would like to have Mr. Pollard e.xpand on these remarks, if that answers tlie (|U('stion. at all, that vou have in mind. Mr. Pollard. Mr. Pollard: It answers it in a way. Mr. McLaughlin, but still I don't believe it goes deep enough yet. I don't believe that the thing has V)een thoroughly thrashed out so we can know what to expect. In order for the meeting to get the idea, and the younger ones coming in, they may "82 STATE on.

Lots of times the men will say. "How do you know?" There are certain things we do know while there are some things we do not know. The action of the mud-laden fluid is of such a character now that we know more about it than at any other time. I have studied the action of the mud fluid for 12 years in America and Europe. I believe that one of the most important things that we have in the business is the action of the mud- fluid, and if it is the wish of the meeting I would be pleased to draw a little sketch and show my idea of its action and just what happens. Mr. McLaughlin: .Inst take the board, Mr. Pollard. I would be glad to have you. .Mr. Pollard : The filtering process that ^Ir. ^IcLaughlin .spoke of is a very good one. It is one that I use myself and use it all the time, but it does not explain all of what happens in a w^ell. We have to take into consideration, with the filtering process, the pressure on the sands that we are treating, and the pressure has more to do with it than the filter- ing effect; and so that, in order to get a clear conception of that prin- ciple, I will take you back to the time when we used to test our boilers with the cold water test. We will take a boiler with a f-inch sheet or even greater. We will fill that boiler with cold water, then we Avould take a low-dow^l pump, and pump more water into that boiler until it had obtained a pressure of three to four hundred pounds. When the pressure was on we would look around and tap the boiler with a hammer until the water would stand on the outside of the boiler in drops as big as your thumb-nail, forced through the boiler sheet by pump pressure. Xow. that is a .serious proposition iu a well. We are dealing with a pre.ssure of a 1000 to 1500 pounds to the square inch. What w'ill that do under those conditions in the ground '.' ^Nfany drillers and operators are of the opinion that the mud-fluid simply walls up the face of a well. I have read from supposedly noted petroleum engineers that the walling up of a well consists of putting mud-fluid into the well and the drillings in returning to the surface are pla.stered up on the side of the well with the nnid-fluid, caused by the Avabbling of the drill stem, no mention being made of the penetrating effect of the mud-fluid back into the formation. This penetrating effect that I .speak of, is one of the most important in excluding water or gas, sealing it into its own formation. It is this same penetrating effect of the mud-fluid that becomes dangerous and sometimes is detrimental, inasmuch as it will load up an oil or gas sand in a manner that will spoil tlie production of wells adjacent to the well that is being treated. I have had analyzed some of the rock from the west side where the- mud-fluid has been in the well, and we have found that the high pressure employed, combating the gas pressure bad really THIRD ANNUAL REPORT. 83 driven the mud-fluid into the rock, and you could ol)tain a trcuioudous amount of the fluid congealed and right into the pores of the hard shell, showing that the pressure was something enormous. I am satisfied that the pressure we put up with the pump did the work. Now then, if the well was 2000 or 3000 ft. deep and we add a pump pressure of 500 lbs. or even greater, it is equal to deepening the well so much more in depth. In order to get a conception of that we will just draw a few formations here (pointing to the blackboard and diagram thereon) this representing the stratified conditions of the ground drilled through. This is a shale; this is rock, and this is sand, and so on down. Now then, when the well has gone through these formations and the mud pressure is on, regardless of what the specific gravity or what the fluid is, there must necessarily be an outlet of the fluid. In represent- ing that, we would say that the outside edge of the fluid as it pene- trates into the formation would be in this shape, (see Fig. 4) . Shale we know would not take as much fluid as sand would, and rock would be less impervious, hence would not take much fluid, so that in treating a section through the formation under discussion we would draw a line more or less (illustrating on the backboard) in this manner. In some parts of the well the formation could be represented as back from the l)ore hole fifty to seventy-five feet, and in some eases even greater, so that we have an irregular line (as described on the blackboard) which would give some idea as to the filtering efi:'ect of the mud-fluid in the various formations. Now then, we have conditions where I have pumped as nuich as three carloads of mud into a well. When I started this in the California fields I was laughed at and called a crank for using mud in this way. How- ever, in sixty days after I did this 1 could see two or three carloads of mud come down from San Francisco Bay for other people who could not obtain results, which shows me conclusively that the men who are using the mud-fluid described in the last pai)er were not particular enough. It is an impossibility to expect the fluid to penetrate the sand you are deal- ing with and shut off gas and watci-. with so much sand in it, as described in the last paper. Since we know that the mud-fluid will travel, as it does in sands, — and we know it b\' the wells that have been stopped pumping by the fact of an adjacent well having been treated witii the mud-fluid system — it behooves us to know just what the action is because if we let the indis- criminate use of this mud system go on. we are going to spoil this terri- tory and undo all the good that the government expected us to do and lose the production of the field wliich we see is opening, so that the situa- tion we have is one of the biggest things we have ever been up against be- fore in our lives. If we attempt to save too much pipe we are going to undo the good that the government wants us to do. It is one of the most 84 STATK OH. AND OAS STTPERVISOR. sci'ious Illinois we li.ivc lo coiilctid with, and we had far better use some ])i])e than to niulo any of the jj-ood. The conditions tliat prevail in Cali- fornia are different from anything else that we have ever had. We have conditions in the Midway fields, California, which should be treated differently from anything else, especially when we consider the cost of drilling a well and the value of the territory. Mr. McLaughlin : I want to thank Mr. Pollard for his remarks, and I want to say that I agree with him that we can not at present issue a blanket approval of mud-laden fluid in all cases. If anybody else has any remarks, I would he very glad to hear them. Mr. T. W. Fuqua : Mr. Chairman, in connection with the problem of nuul-laden fluid, it has always seemed to me to be, strictly speaking, the most scientific Avay of mudding off either water, gas, or oil-bearing forma- tions that are apparently beyond the hopes of satisfactorily cementing off, through and by use of the regular methods of applying a cement for the purpose of excluding water from formations containing oil, and we have two instances in the Coalinga field, which have proven con- clusively and to our entire satisfaction that mud-laden fluid can be made, if properly handled and mixed, and applied, to accomplish almost any desired results, and while our work can not be commented upon as being first class in character, nevertheless our intentions were good and we did the best we could under the circumstances, and believe that in a great many of the most serious and the most dii^cult of jobs, they could be handled most satisfactorily if the consistency^ of the mud is carefully prepared, forced in under whatever pressure that may be desired, and continue the process as long as it may be necessary, and I believe that greater results can be accomplished than have heretofore been effected, and prevent in a good many cases the shooting off of casing in a horizon or zone where a condition of this kind would only complicate matters and prevent the final completion and accomplishment of the task that was at first undertaken. Our Well No. 8, Section 19-20-15, we were satisfied was more or less of a trouble maker in the way of allowing water to pass down from behind the one-time cemented casing and into the oil sand, and into other wells to the south, which were being considerablj^ interfered with in their production of oil. In this well we had a great deal of casing trouble. As a matter of fact, it was in bad shape, and after considering the matter from every angle we decided that the mudding process would be the most logical solution of our difficulty. Mud was pumped in of various consistencies and under various pressures, from running it into the hole up to 200 pounds per square inch. This process was continued until such time as the well refused to take any more fluid, and immediately thiereafter we observed an appreciable decline in the amount of water and a perceptible increase in the production of oil in adjoining wells TIIIKI) ANMAl- KKl'Oirr. 85 5urface'c;Pm\ Sketch Showing PENETRATION OF MUD FLUID In V3rioU5 formations By John A.

Roughly speaking, in Well No. 7, which was approximately 350 feet south, in May, 1917, the oil production was only three barrels per clay, the water running from 90 per cent to 98 per cent. The mud- ding off of Well No. 8 was completed in the month of July, 1917, and in August Well No. 7 came up in its production of oil to 20 barrels per day, and in December to 22 barrels per day, and in January and Febru- ary this year 22 and 30 barrels per day, respectively, with an appreciable decline in water. Well No. 6, which was the next one south of Well No. 7, showed a decline in oil from 40 to 45 barrels to 12 barrels during the period when we believed that water was infiltrating into the oil sands in Well No. 8, and in Septeml)er,. 1917, Well No. 6 had increased its production to 20 barrels of oil per day with an appreciable decline in water, and in October the production in oil had risen to 28 barrels. In January this year the well produced 36 barrels of oil per day with a considerable decline in water, and we have reason to believe that there will still be a further decline in the production of water and perhaps a little further increase in oil. The oil sands, however, in this part of the district having been produced from for a number of years, there is not and never will be very much of an increased production. The main point will be to preserve the developed channels, through which the oil has been traveling to the various wells for a number of years, as much as possible so that the flow of the oil to the wells will not be interrupted by foreign substances of anj^ kind, and to prevent, wherever it is pos- sible to do so, the admittance and infiltration of water into the produc- tive oil sands. I am advised that in some of the Eastern fields water is being run into oil-bearing formations for the purpose of chasing out the oil, and I understand that it is liighly successful, but I do not believe that we will ever find it necessary to resort to this princi[)le in this particular district in the C!oalinga field. I think and believe that plenty of water will get in without having to intentionally break it in. We have another Well No. 34 on Section 6-20-15, which gave us a great deal of concern and required a great deal of thought and eflPort before we were able to determine the exact source of the water, which was found later on to be a bottom water. Before this determination was made, however, a plug was placed below the cemented casing and the well was bailed dry, which indicated immediately that the water was coming from some other source, and in continuing our efforts it was finally decided and located in the bottom, after which we mudded up thoroughly and put in a cement bridge on top. The well was making, before the water broke in, approximately 100 barrels per day. After we finished with the nuidding process and after the water had stood on the sand for a coiisideral)le length of time, we find that the well is now mak- ing 75 lianvls of oil with al)out 15 per cent of water.

The American Petroleum Company, upon the suggestion of State Oil and Gas Supervisor, R. P. ]\IcLaughlin. recently abandoned Well No. 8, Section 19, T. 20 S., K. 15 E.. Coalinga field, protecting the oil sands from water by the use of mud-fiuid. The work was approved and inspected by tliis department, and its etfectiveness is beini:' demonstrated l)y the productiou of sui'i'ouuding wells. u\t)audonment was necessary since meclianical troubles made it doubt- ful whether the 8|" casing could be successfully re-cemented to shut out top water. The 10" cemented at 1712' was originally the water string and the well produced for several years from the sands below it. Later, edge water appeared in the ui)per sands and was shut oflt* with the 8^" easing at 1885'. In preparation for the mudding and abandonment. 18H1' of 5§" and 1826' of 8|" casings were pulled out and the 8|" carried to 1980' and the well cleaned out to 200-1'. ?klud-tiuid was obtained by mixing the surface formation, which was fairly good clay containing a small amount of fine grained sand, with water. A foi-ty hoi'se-power boiler and (jumbo Huster pump were set sDiiic 900' south of the well where the mud was mixed by circidatinz the Huid tlirough the |)ump and discharging it through a hose into a 50' x 75' shallow i-esei'voir made by plowing the ground and banking up the sides. Tlie sand settled out to a great extent before the fluid reached the suction box at the pump. By adjusting the valves the pump discharged directly into the top of the 8]" casing at the well through a 2" line. The work at this plant was attended to by one man, with occasionally an extra helper, and the work at the well by two drilling crews of two men each. No figures are available as to the yards of material pumped into the well, but some idea nuiy be gaim^d In' an estinuite of the time during whicii mud was being introduced into the well. The total time consunu'd in mudding, moving casing, plugging, cleaning out, etc., was 46 days of 24 hours and on every day except six mud was pumped into the well a portion of the time, occasiniially with the 2" valve wide oj)en, Itut gen- erally barely opened, allowiuir just eiKniy^h fluid to run in to keep the hole full but not limning over-, bet WITH the SJ" ;iiid 10" casings. In that 88 STATK OIL AND (!AS SUPERVISOR. manner the oil sands took all the mud put in, the quantity gradually- decreasing, until the hole stood full under the hydrostatic pressure only. A casing head was then put on with packing clamps between the 8^" and 10^' casings and more mud pumped in until the pressure was up to 200 pounds and fell only 20 pounds in one hour. For the first 16 days the S^' easing was kept at 1927' and the sand at that point mudded first, until it required pump pressure to force mud into the well. The casing was then lowered to 1976' and the sands below 1990' mudded in the same manner. Plugs of brick and rope were then put in from 2004' to 1494'. The casing was then pulled up to 1784' and the upper sands mudded under pressure. During the first portion of the work the mud-fluid was rather thin so that the mud would be deposited in the sand voids for a considerable distance from the well, thus building up a body of formation around the well which will be impervious to water. As the sands became clogged with mud, the fluid was thickened and the final column of fluid stand- ing in the well to the surface is of maximum densit.y and its hydrostatic pressure greater than the water in any stratum of sand, and thus will confine all waters to the sands in which the}' occur. Evidence that the mud-fluid traveled away from the well when the fluid was thin is had from the fact that muddy water on the fifth day appeared in succession in the production of Wells Nos. 7, 6, and 5, being more pronounced in the nearest one. No. 7. distant 332' south, and least in No. 5, distance 1000' vsouth, and discontinued after the fluid was thickened and required pump pressure to force it into Well No. 8. Careful gauges of Wells 5, 6 and 7 taken during the month of August, 1917, during the mudding, show the following daily averages: Bbls oil Bbla. w«ter Well No. 5 Well No. 6 13.4 n.e 18.0 340 187 Well No. 7 - - - - - -- •'27 Totals - .- 43.0 763 Similar gauges taken during February, 1918, six months after com- pletion of the work show the following daily averages: Bbls. oil Bbls. water Well No. Well No. ^. 23.4 31.1 34.« 245 1C» Well No. 7 156 Total- 89.1 570 Tlllltn ANNUM; REPORT. 81) This shows a total increast' in oil of 46 barrels per clay and a total decrease in water of 198 barrels per day. The approximate cost of abandonment at Well 8, ^iven by the American Petroleum Co. was $1,831 for labor, material, oil and water. No credit is given for 1864' of 6|" and 1826' of Sy .second-hand casings, and taking into account the additional production of oil. a substantial balance on the credit side is shown for the work. Mr. I\IcIjA[JGhlin : In connection with that paper I would like to call attention to something that probably might, at first glance, have no bear- ing on this subject. That's the method in which wells are gauged. I have noticed that there is a very careful system and a very good under- standing by the American Petroleum Co. in the Coalinga field in the manner in which they gauge wells. I would like to have either Mr. Crumpton or Mr. Fuqua tell us why they gauge wells and how. ^Ir. Fuqua : I would suggest that Mr. Crumpton do that. Mr. T. J. Crumpton : Mr. McLaughlin asked me to explain why it was necessary to gauge this water and oil in such a numner as I have done. I would like to state now that the reason that I have done this is on account of the department pounding me on the back all the time METHOD OF GAUGING OIL &. WATER AT WELL AMERICAN PETROLEUM CO.

Well Xo. 51 had been abandoned by the :\lonte Cristo Oil Company and in order to shut off the water the w^ell had to l)e redrilled and top and Ixittom water both shut off. The hole was redrilled with 12^" ca-sing to 545' and cemented with 12^" casing at this depth with 50 sacks of cement and 20 sacks of hydraulic lime.

Puni{)ed mud in under 250 pounds pressure after getting circulation and followed it with 3i tons of cement. The work of shutting otf hottoM) water in this M'ell was successful and it also shut off the water in Well No. 65. Before working on this abandoned hole, No. 65 was blowing 2000 barrels of water per day and no oil, it now makes 10 barrels of oil and very little water. In all the work we have done in the old Kern River field, with one exception, to shut off the water, we have used mud to seal up the sands to stop the flow of water preparatory to cementing. The water on the old Mcnte Cristo property is constantly moving in the sands and this is proved by the sudden rise of water in the wells when some of the big water wells are shut down. Water has also been observed rvinning in a well through a hole in the casing, without filling up the well. With this constantly moving water it is obvious that attempting to cement strings of casing or i)lugiiing with cement alone would be of no value. In one job (Well No. 51) when shutting off bottom water, mud alone was used and forced into the formations under 275 pounds pressure. The 7§" casing was carried to the bottom (1014') of this well and after thoroughly mudding. the 7|" casing was withdrawn and the hole left full of mud. This well has been standing for one year full of mud. From the work we have done in this field, it might appear to those not familiar with the Kern River field conditions, that our work would only be of a temporary nature, having been done with such an unstable substance as mud. However, it appears to me that under conditions as they exist in the Kern River field and under similar conditions the use of nuid as we have used it in the wells described is entirely feasible. In deep wells the use of mud does not appear to be so desirable. In case of a Kein River well, which has been mudded, again becoming a channel for flow of water into the oil measures, it is possible to open the old hole and re-seal the formations, in a deep hole it is doubtful whether the well could be successfully re-mudded. Were it pussi])le to make tests on a well and to re-mud the formations if necessary after the casing had been landed through th* mudded formations, it could be kept sealed and the sands would so remain impervious to the flow of water or oil. In most cases it would be impossible to i)ump mud behind a string of casing after it had been landed for any length of time. This I believe would be especially so of a long string (3000') of easing, Avhich had been landed in a rotary hole. It might be possible to pump mud a short distance up behind the shoe or a short distance down from the surface on the outside of the casing, but l)ridges which would occur due to the caving ol" the walls of the hole against the pipe would prevent the hole TiiiRu anni'aIj report. 93 from cvor Ikmiij^ rc-imuldcd and also render nsoless, observations as to whether the hoU» on tlie ontside of the pipe was full of mud. In the ^Midway field mud was used under similar conditions but the effect on the surrounding wells was very different. During the abandonment of jMidway Oil Company's Well No. 9, on Section 35-21-24. nuid was pumped into the oil and gas sands, the mud showing up in Standard Oil Company's Monarch No. 4 gas well, located about 250' away, having a very unfavorable effect. Before mudding the .Midway Oil Company's well, ^fonarch No. 4 made about 1,000,000 cubic feet of ga.s per day and had been making that amount for over a year; after the mnddiug tlie well bi^gan making mud and now does not make any gas. Another instance where mud had a deleterious effect was when Eagle Creek No. 21 was to be abandoned. Tubing and rods had been lost in the well and when we proposed to abandon the well we endeavored to seal the oil sands by pumping mud down the hole. This mud went directly into the oil sands and was pumped out of Honolulu No. 12, whicli is about 600' away and down the dip of the formations. Honolulu No. 12 decreased in production from 100 barrels to 35 barrels and to date has not come back. From the use of mud as we have seen it, we have had very favorable results in the Kern River field and very unfavorable results in the Mid- way field. This is no doubt due to the different conditions of the sands, structure and character of the oil. The use of mud seems to meet with more favorable results when used in shallow wells producing heavy oil than when used in deep wells producing light oil (25° gravity) and gas. In conclusion I may state that mud has its uses but great care should be taken that low pressure productive oil and gas sands are not sealed up so that they will not unseal themselves, and also, that when mud is used to mud up sands when landing water strings, it seems advisable to follow the mud with cement. C. C. ScHARPENBERG : Mud has been used in the drilling of oil wells by the rotary system in California for man}^ years, having been intro- duced here from Eastern fields. It has been found in drilling that nuid is necessary for the successful completion of wells through certain sand and shale strata containing water or gas, and the use of drilling tools adapted for working with nnid-laden fiuid had therefore increased until at the present time such tools are used almost exclusively. Mud is usually considered to wall up the hole, mixing with the sand or other formations so as to give this material an angle of repose of 90 degrees. This angle of repose will be maintained usually for four to six hours, or perhaps longer, varying with conditions of use and forma- tions, but should a I'otary hole Ih- kci>t full of nuiddy fluid and left 04 STATE OIT, AND GAS SI'PERVISOR. stamlino; iiidcfinitcly it has hccn proved in many cases that a new bal- aneinii; of ])iea-ss it to your neighbor, please: M.

REPORT ON MUDDING AND CEMENTING OPERATIONS AT RANCHO LA BREA OIL COMPANY WELL NO. 41.* Sec. 15, T. 1 S., R. 14 W., S. B. B. & M., Salt Lake Field. Along the line of development of the mudding process for excluding water from oil wells, which process has })een used successfully in numer- ous instances in California, the following mudding operation is described more or less in detail with the idea that other operators confronted with similar problems may profit by the experience of this company in attack- ing such problems when the more common method of putting in cement plugs has failed. Rancho La Brea Oil Company Well No. 41 was completed in Sep- tember, 1911, at a depth of 955 feet, and made an initial production of over 100 barrels of oil per day and no water. The production of this well dropped considerably from the initial production until January 24, 1916, on which date the company filed a proposal to deepen this well and cement a string of casing below the oil sands, in order to protect them from water, which they expected to develop at a depth of about 1800 feet for use on the property. Water sand was unexpectedly encountered at a depth of 1123' and *See also Chapter III, page 2?,i), post. THIRD ANNUATj REPORT. 101 ])enetrated to a depth of 1285'. Drilling operations were stopped when tlii.s depth was reached and several attempts were made to plug the bottom of the well in order to protect the oil sands from water. Various methods of bridging and cementing were employed by the company and by cement experts, but without success. Accompanying this article is a cross-section showing certain wells of Kancho La Brea and Salt Lake companies. A map showing the posi- tion of wells included in the cross-section is also given, (Pig. 6). Study of this cross-section shows that fairly regular geologic conditions exist in this area of the Salt Lake field. It will be noted that Rancho La Brea well No. 41. shown on the cross-section, has been drilled deeper into the formation than any of the other wells shown. A peg model con- structed by this department shows that in general the formations dip in a southwesterly direction from the Rancho La Brea Company prop- erty on Section 15 towards the Salt Lake property on Section 22.

Detailed information i-euanling the physical condition of the well was n'(ineste(L and subse(|uent ly received from the 102 STATE OIL AND (JAS SUPERVISOR. company. A study of these records and an interview with the field superintondent of this company, jNIr. F. J. Prehoda, brought out the fact that cement previously placed in the bottom of the well, was carried back into the formation. This probably accounted for the failure of the various cementing jobs to shut off the water. This department recom- mended that the (ompauy pump mud-biden fluid into the sands near the bottom of the well. Mr. Prehoda, who has had considerable experience in the use of nuid-laden fluid, readily agreed to try the experiment, and co-operated with the State Mining Bureau in the matter of eliminating the water trouble which was spreading to adjoin- ing wells on this and neighboring properties. Previous to the beginning of mudding operations, Mr. Prehoda reported that the well had been bridged from bottom (1285') up to 1100', Avith brick and rocks driven down by the tools. On May 10, 1917, the bridge was drilled out to a depth of 1185' and mudding operations started. The oil string was set at a depth of about 1100', and mud about the consistency of rotary mud pumped into the well through three- inch tubing which extended to a depth of 1168'. About 24 hours after mudding operations were started in this well. Salt Lake Oil Co. Wells Nos. 329, 330, 347 and 348 and Rancho La Brea Oil Co. Well No. 38, pumped water carrying considerable nuid. Upon request from this department the wells of the Salt Lake Oil Co. producing this nuid were .shut down. After mudding operations had been in progress for over a month without any apparent success to mud up the formations, this depart- ment suggested that sawdust be used in addition to the mud in order to stop up the pores, or openings, in the formation penetrated by the mud. A favorable effect was immediately noticed in that, shortly after- wards, June 21, circulation was obtained. Following this, the well was thoroughly mudded by forcing mud-laden fluid into the formations under a pump pressure of 400 pounds per square inch. The well was shut down, leaving the mud-laden fluid standing at the surface. Mr. Prehoda reported to this department that a total of about 700 cubic yards of adobe and 40 cubic yards of sawdust were pumped into the well during the first mudding operation. On August 1, 1917, the mud was washed out of the well and the well bridged from 1109' to 1095' by tamping rock into the formation and the bottom of the well cemented with 50 sacks of cement pumped through tubing, bringing the top of the cement plug up to a depth of 1080'. After cementing, the well was allowed to stand about three weeks and put on the pump and produced between three and four hundred barrels of cleai-, salty water per day. No nuid used during mudding operations appeared in the well. TIIIKD ANMAL HEPOKT. 103 About a month after the cementing of Well No. 41, water again broke into Raneho La Brca Well No. 38. Subsequent to water breaking into this well, Ranebo La Broa AVell No. 41 was mudded a second time. This latter operation was started on November 13, and was finished on December 4. During' this second mudding operation, four feet of the cement plug in the bottom of the well were drilled out, five old bull- ropes cut into three-inch lengths mixed with adobe, about 70 yards of adobe and 10 yards of sawdust were pumped into the well under a pressure of about 4(H) pounds per square inch. During this mudding operation, Raneho La Brea Well No. 38 was shut down. On December 11, when the pumps at Raneho La Brea Well No. 41 were practically "stalled" and the well taking only a small amount of mud, Well No. 38 was put on the pump and began to pump muddy water. Well No. 41 immediately began to take more mud. For three days Well No. 38 pumped muddy water and then started to pump a small amount of oil. According to the production report, this w^ell produced 300 barrels of oil and 200 ])arrels of water during the month of December, 1917, while the mud-fluid stood at the surface in Well No. 41. The information relative to work done at the first and second mudding operations at this well were furnished this department by ]\Ir. F. J. Prehoda. Accompanying this report is a statement showing the monthly pro- duction of oil and water of Salt Lake Oil Company's Wells Nos. 329, 330, 347 and 348, and Raneho La Brea Oil Company Well No. 38. These welLs were directly affected, and produced mud during the initial mud- ding operation of Raneho La Brea Well No. 41. This table shows that these wells averaged a total of about 500 barrels of oil and 4445 barrels of water during the months of January, February, March, April and May, 1917. This was before Rnacho La Brea Oil Co. Well No. 41 had been mudded up. The table shows that tliese wells were shut down during June and July. From August to January inclusive, these welLs averaged 2259 barrels of oil and 4230 barrels of water per month, show- ing a net average increase of oil to 1759 barrels per month. This increase of oil is pr{)l)al)ly due to work done in mudding Raneho La Brea Well No. 41. It is interesting to note at this time that the well is standing full of mud-laden fluid up to a depth of 140 feet from the surface, and from this depth up to surface, the well stands full of clear water. Previous to mudding operations, fluid stood at a depth of 173 feet and could not be lowered by bailing. The fact that mud-laden fluid and water stands at the level indicated, tends to y)i-ove that water is not p0 5,963 3,805 4,-252 3,475 1,268 5,235 4,905 4,698 4,85S 4,424 *Shut down. +No report. Mr. Prehoda : In regard to Well No. 41 it was water we were after, being unckn- the impression it was good boiler water. We intended to carry 6;^ (basing to the first shah' below the oil sand and land it; but as the oil .sand was running in we were unal)le to tell when the shale had Ix'cn reached until water liad made its ap])earance. The water was not THIRD ANNUAL REPORT. 105 noticeable until we reached 1190' then it raised within 170 ft. of the surface. The well was drilled to 1248 ft. then the water tested as to its value for boiler i)iirposes. Finding the water of no value we pro- ceeded to plug the well and shut the w^ater off. I had the well plugged to 1180' and cemented. After letting it stand three weeks, had it opened to test and found there was no cement; it must have washed away. Then it was plugged up to 1120' and again cemented it stood for three weeks more, and tested only to find the same results. The well was cleaned out and the 6:5 casing was allowed to follow, after which we found that shale had been gone through from 1085' to 1118'. The well was bridged to 1090' and w^as cemented. After standing a period of three weeks wa.s tested and found the cement set but the water was not shut off. The well was pumping one month and produced only warm salty water. After consulting Mr. Kirwan we agreed to mud the well in hopes of mudding the passages which we thought w^ere leading from this well to our No. 38 a distance of 500' away; also the Salt Lake wells which are from 1500' to 2000' distant. I had used the mud two days wlu'u Mr. Foster informed that his wells on the Salt Lake were pumping mud. After imparting this information to Mr. Kirwan he took the matter up with Mr. Wooten and wells were shut down and mudding started again. About 600 yards of adobe were pumped in, but could not get any circulation. ]\Ir. Kirwan suggested that I get some sawdust and mix it in the mud, which I did, and after using some 25 yards, finally got a circulation ten to fifteen minutes at a time and the fluid would disappear. It continued this way for a week or ten days. Each day the circulation remained longer until the fluid did not leave. I kept circulating for one week and then let the well stand for about one iiiontli. Then I consulted ]Mr. Kirwan and w^e decided to pump the wells; tiic Salt Lake was notified and I started No. 38 on our property and it went to making oil the first day and the Salt Lake wells also sliowed more oil than they had for months before. After four weeks our Well No. 38 went to pumping mud again. I at once went to Well Xo. 41 and found that the fluid had gone dow'n to the water level of 170'. Put a crew on mudding it again. This time I used bull rope chopped up fine and 8 yards of sawdust and 60 yards of adobe. Had no trouble in getting circulation and I had 400 pounds pressure put on the well after the pumping was started. I had No. 38 started to see if it would have any effect on the pressure and I found that it did. So I had the crew pump in mud for two more days when the pump was stalled again. Then let the well stand four weeks more, when starting it again it pumped muddy water for two days when oil began to appear and in one week was pumj)ing 30 per cent oil and has been improving daily and ;it tliis writing is doing 50 per cent oil.

We drilled about 20' further and then cemented the 8|". The cement set that time all riafht, but the Avater was still there. We couldn't get circulation. I had a hydraulic pump there — 2200 pounds pressure on it. I stated that we couldn't get circulation. I then got this mud and a tapering shoe. I drilled the hole ahead, got the nnid all ready and I circulated the mud awhile and drove my shoe down into this small hole — I did not wait for it to set — but I bailed it out and let it stand for seven days and the well was just as dead at the end of seven days as it was the fii'st day. From that time I went to using mud. Mr. Kirwan: What was the depth of that well, Mr. Prehoda? ]\1r. Prehoda: On the drilling Avell? I think it was 1200'. ^Ir. Kirwan : Do you think that was a combination of formation shut-off or due to the mud only? Mr. Prehoda: I think it was a good deal the mud. ]\fR. Stoner : From the description of Well No. 41, all the nuid you pumped went into the oil sands. Mr. Prehoda : I had my 6f '' down below the oil sands. Mr. Stoner : It is a question in different areas whether or not the oil would stand that much mud and come back. ^Ir. Prehoda: I don't know. I never pumped 11. Forty-one stands today. Q. The mud you used was all black adobe mud? A. Yes. All black adobe mud. Every day when we pumped this mud in the well we would first shovel all the sand that accumulated in th(^ bottom of this sump hole out. Q. How do you figure the oil got into the |)ay sand? Did the saw- dust stay out of your well into the l)ottom water sand ? A. Yes sir. and followed that channel. I have wells much closer than the Salt Lake that were never affected at all. In fact, I have one well that's in front of one of the Salt Lake wells and it is not affected, yet one of their wells was affected. It shows that there must be an underground channel connecting those wells together. Mr. Stoner : In mudding up wells like that, the mud would follow the line of least resistance. Mr. Prehoda: The reason I don't think there is mucli mud in my own sand is this: I think after you nuid a certain length of time, the mud accumulates below the shoe and would keep it out of the oil sand. I think it coats over just the same as in a rotary hole. Q. This rotary mud that you used; was that ligiit? A. No, it is heavv. THIRD ANNUAL REPORT. 107 A PROCESS FOR REDUCING THE VISCOSITY OF HEAVY OIL. By E. A. Starke.' Tlu' oils of tli(- Casinalia section of the Santa Maria fi('l(l are of an exeei)tioiialIy viscous and sticky nature. Their gravity ranges from some 8° to 16° B. AVith an average gravity of some 10" B. combined with liigh viscosity, it i-- impo.ssilih^ to commercially transport them by sneh means a.s pipe lines without subjecting them first to a preliminary treat- ment to raise their gravity and lower the viscosity. It is only during the past few years that the importance of the heavy oils has been realized and their intensive exploitation carried on. For- merly these heavy oils had a limited use as road building materials, and in the nuiuufacture of asphalt. As soon, however, as the refiners of light petroleum products placed the residuum from their refining operations on the market for the same purpo.ses the demand for heavy petroleum fell off. In view of this, the heavy oil fields, such as those existing in Santa Barbara County, were neglected. Renewed interest, however, was taken in these fields when the demand for fuel oil rose to the figures we are witnessing today. In order to be commercially useful, as a fuel, these heavy oils must be capable of transport through pipe lines without the application of heat, and, furthermore, their nse must not be restricted to apparatus having specialized heating arrangements. For the extensive fuel utilization of the Casmalia crude, a certain pre- liminary treatment is necessary in order to bring it up to the required standard. This treatment has heretofore consisted of heating the oil to a temperature of 180° F. and mixing therewith light distillate in a special type of mixer. In this way a high quality product is obtained which can be transt)ui-t('d through a pij)e line, and which meets tlic fidl market demands. A niunber of objections arise against the above mode of treating the heavy crude, chief of wiiich are the high cost and scarcity of light distil- late, and secondly the fact that production of the mixed product is dependent on the supi)ly of light distillates obtainable. A third impor- tant objection rests on the ground that full value is not obtained from the crude oil in this manner. For these reasons other methods of treat- ing the cnule were found imperative, with the result that the Doheny- Pacific Company adopted, at its Casmalia property, a process patented by the writer in 1905, and which had already been proved commercially successful. The Starke i)rocess is l)ased on llit» i)rinciple that when a heavy aspliallic oil or fesiduuiii is heated 1o 7(M) V. the crude oil sutlers dis- sociation or ci'aekiiiir. particularly llial |)ai-1 of the erude which renders 'We are onal>leiilili.s|i tlii.s aitii-1'' tliroiish tli"' ituiitrs.v nf 10. .\. Starke, Clieniit-al Knginter, Herkelcy, California. 108 STATE OIL AND GAS SUPERVISOR. it sticky and viscous. In order that the process can be carried out suc- cessfully it is necessary that the oil be dry, as water interferes with the cracking operation. Not only does this method reduce viscosity, but a certain percentage of synthetic gasoline is formed. If it is desired to obtain a large percentage of this cracked gasoline, it is necessary to employ pres.sure. However, even when the prime object is to reduce viscosity, from 3-6 per cent of synthetic gasoline is formed during the operation. It is advisable in all events to so employ the process that the largest amount of synthetic gasoline under the given conditions is obtain- able. In this way the operating costs are lowered. In a general way the process as it is practically carried out consists in pumping 100 barrels of dry oil into a 125 barrel still. Approximately 40 barrels of oil is now distilled off. The heat under the stills is then discontinued, and the distillate is reunited with the residuum contained in the still. This may be done either by first cooling the still and adding the distillate, or by mixing the distillate and residuum without pre- liminary cooling. The last method is the one generally adopted. In this way the cold distillate is thoroughly mixed with the heavy asphalt still bottom, at the same time cooling the mixture sufficiently so that the charge can be withdrawn. The resulting product has now a gravity of between 11-12° B. and the viscosity is about equal to that of a 16° B. Kern River crude. The heat units per barrel are equal to those of the Kern River crude, about 18,800 B.t.u. but being of a lower gravity. A barrel of this processed oil will produce more steam than a barrel of the Kern crude or residuum. The viscosity of the oil produced will necessarily be dependent on the amount of distillate taken from the crude and then reunited. If, however, more than 50 per cent of the crude is removed during the distillation process, a certain amount of carbon is formed which would be classed as an impurity. Actually this carbon is so finely divided that it does not interfere with the uses of the oil. During the distillation from three to five per cent of the oil is given off as a gas which contains much of the sulphur present in the well. This gas is burned under the stills as fuel. Considered in detail, the plant as operated on the Doheny property presents the following features : A continuous distillation system utilizing a battery of four stills working as a unit. These stills are of 600 barrel capacity and are pro- vided with the necessary preheaters, condensers and other distilling accessories. Comparatively dry oil is pumped through a heat exchanger into still number one. Here the temperature of the oil is raised to that point at which the most volatile fractions are given off. The oil then passes from the bottom of this still into tlic center and back section of still number two, maintained at a liigher teinp(»rature than still number TffIKr> ANXIM; KFT'ORT. 109 one. IIltc a soeoiid fraction is is givoii oil', aiul passed into tho con- denser. From still nuiiiher two the oil fiows into the center of still number three, maintained at a higher temperature than the preceding two. Here a third portion of the volatile constituents contained in the oil are given off. From the third still the oil flows into a fourth one. Here the oil attains a temperature of about 750° F. and the remaining fractions distill off. The residuum of still number four is now passed through the inner tubes of the heat exchanger before mentioned, where it loses a part of its heat to the incoming crude. From the heat exchanger the residuum Hows into a sort of churn where it is mixed with the distillate portions recovered from the various stills. The resulting mixture is now limpid and can be pumped and u.sed in the same manner as the 16° B. Kern River oil, and is e(iual in qualitj' to the best crude used for fuel purposes. In conclusion it may be stated that with the increasing use of syn- thetic gasoline as a source of motive power, the heavy petroleum oils assume an important role from an economic standpoint, and such methods as the one described, by which both high grade crude fuel oil and synthetic gasoline are obtained, merit the attention of the oil producer.

AH of the iiKH-hanical operations at a drilling well which aim at the protection of productive oil or gas bearing formations from infiltrating waters, and also certain geologic featuras, contribute data for determin- ing the result of the test for water shut-off. These data include : (1) Total depth of hole and depth to which hole is bridged to land water string. (2) The method of drilling: Rotarj- or Cable. (3) The diameter, weight and length of casing used as water string. (4) The method of making water shut-off. (5) Such natural features as stratigraphic position, chemical com- position and hydraulic head, or fluid-level, of water or waters excluded. (6) Record of all other formations entered, both above and below the depth of shut-off, including oil, gas and water. In this pai)er the various items specified above are discussed only as they apply to operations for shutting of top or intermediate waters in the oil fields of California. Definition of Terms. Water shut -off : The term water shut-off is commonly applied, in California, to the condition whereby waters, native to strata penetrated in drilling, are excluded from the w^ell and prevented from moving below a given depth, hy landing or cementing a string of casing at that depth. Top water: The term top water is applied to waters overlying the shallowest productive oil zone in any given area. Litermediate water: The term intermediate water is applied to waters native to strata lying between anj' productive oil zones. Water string : A water string is a string of casing which is used to exclude water from an oil well. Source of Data. The officiaP reports on test of water shut-off of the Department of 'There are two kinds of reports issued to operators: (1) Reports on Test of water shut-oft; and (2) Reports on Proposed Operations. Tlie reports all bear serial num- bers showing the kind of report, the district from which the report originates, and the individual number of each report. Thus, Report No. T 1-24 is Report No. 24, on test of water shut-off, originating in District No. 1. Likewise, Report No. P 3-56 is Report No. .56, on proposed operations, originating in District No. 3. Each of these reports bears a decision or recommendation, either relative to a test or to certain proposed work. The decisions of the re.spective districts are .summarized for the Annual Report, and appear under the sulxject "Decisions," in the chapteis covering work reconnnendations on "Reports of proposed operations for the Coalinga field"'. Report P 5-Sl recommends shutting off water at 2870 feet instead of 2855 feet as proposed. Rejjort No. P 5-100 reconnnends that water be shut off at li)SO feet instead of 1055 feet.

It must be noted, however, that tliis operation would l)e j)raetical)le ouly in an area, such as this one, where forniational eonditions are exceptionally favorable and thick beds of shale give the necessary lee- way for successful landing of water string with rotary. For example, the following is a portion of the log of a well in this ai-ea^ which aptly illustrates the advantageous conditions for formation shut-otf : 11-iuch, 47-pound casing landed at 2255 feet.

The foregoing shows a range of over 400 feet of formation, almost any part of which would be suitable for formation shut-oif. It may be added that the same character of formations are shown in this log from a depth of 1450 feet to the depth at which the above record begins. For the immediate purpose of excluding water at the shoe, the forma- tion shut-offs, referred to above, give satisfactory results at test. The percentages of formation shut-off s, made between various depths, have already been given. In Table XIII the percentages of failures of formation shut-otf for the several depth groups, previously used in this paper, are shown. Possibly more accurate representation could be based on a segregation by frietional depths, that is, length of water string in contact with formation, either to the surface, where no other casing has been n.sed, or to the shoe of the next larger conductor casing. This table shows the total .successes and failures for both formation and cement shut-off. It shows the gross percentage of failures for each method of shut-off and the average percentage for both methods. It also shows the number of successes and failures for each method of shut-off under segregation of (1) water strings landed with cable tools and (2) water strings landed Avith rotary tools. Formation shut-offs are restricted to the shallower wells. Dead- weight of casing and forniational friction prevent successful driving in deep holes. Comparison of data in Table XIII shows a smaller per- centage of failures for formation than for cement shut-offs. In making 'See Table IV, See. 35, T. 31 S., R. 23 E., Sec. 9, T. 32 S., R. 24 E., M.

On tlie other hand, it is probable that cement jackets or thick nmd around water strings will insure greater life to the easing through protection from corrosion. The subject of corrosion of water strings in formation shut-olfs deserves serious consideration. The operator should determine the cor- rosive properties of the water to be excluded before a final drilling pro- gram is adopted. For example, Deputy Supervisor Kirwan/ when at Coalinga, reported an extremely corrosive condition as follows: "Four wells surrounding Traders Oil Co. well No. 41 show an average production of 35% ennilsion and water. Mr. McQuigg's- letter dated Jan. 81, 1917, states that water eats out the casing in from three to five years duration and I'equires replacing." ]\rr. Kirwan suggested that this condition could be overcome by cementing water string with the Perkins or any system that will force cement back of the pipe, for a cement jacket, to top of the well. In the First Annual Report' the writer noted a number of instances of failure from corrosion. In five wells in the Pinal Dome-Hobbs area, Santa Maria field, top water ate through two strings of casing, 124-ineh and 10-inch, in each well, in an average time of six years. These were foi'mation shut-oft's. Cement Shut-off. ('ement is used in shutting oft' water for the primary jnirpose of making an impervious bond between the foot of the water string and formation in place. There are a number of secondary purposes, for which varying amounts of ceme.nt, in excess of the quantity sufficient for excluding water at the shoe, are placed back of the casing. The principal secondary purposes are the following: (1) Cement jaeket ai'ound casing to prevent corrosion. (2) Cement jaeket around casing to reinforce same against col- lapse. (3) Cement seal, filling space between outside of casing and wall of hole, to prevent movement of all flnids or gases from their native strata into other susceptible strata exposed 1)V the drill. f4) Cement seal, filling si)aee between outside of casing and wall of hole, to prevent the expulsion of mud fiuid from porous formations into which it has been placed under pressure for the purpose of rendering said formations impervious to movement of water, oil or gas.

The cement is pumped either througli the casing or tubing, depending upon circumstance.s. The Perkins Process comprises a patented feature of wooden plugs which are i)laced in the casing, one going ahead and the othei- foUowing the cement tluid as it is pumped. Tlie first i)lug lodges in tiie bottom of the casing, which is lifted off bottom while pumping cement. Wlien sulhcient water, which follows the second plug, is pum|)ed into the casing to displace the cement fluid the two plugs come together at bottom. There is a disk of rubber belting attached to the second plug and fitting the casing snugly. This disk acts as a valve and stops further circulation after the plugs come together. Two plugs are not always used. Report No. P 3-56, listed under Decisions, Casmalia field, Doheny Pacific Petroleum Company, well No. 1, Lease 2, gives the details of the various steps in a shut-off job by the Perkins Cement- ing Company. The distinctive feature of the Scott method is a specialization, covered by patent, of the tubing method of cementing. The patent covers a casing head packer, with relief port, for use with tubing in I)umping cement back of the casing. - If necessary the cement fluid, in tubinj^ and casing, can l)e displaced with water through this port. In the Scott process the cement is mixed in a hoi)per alongside the l>ump. Cementing is done by Scott, however, without the use of tubing. In fact, tu])ing is used only in cable-tool holes with short friction where there is no danger of freezing casing. In rotary jobs the cement is ]nnnped through the casing and is displaced from the casing by following it with mud-fluid. In the tubing inethod the cement is pumped to the bottom of the hole, and behind the casing, with a string of tubing. Sometimes a casing packer is placed near the bottom of the tubing for the purpose of directing all cement fluid back of the casing. In other jobs the tubing is set in a easing head packer. In the latter ease the hole is completely filled with water to prevent return of cement fluid into casing. There is danger in the tubing riiethod of not being able to pull tubing before cement starts to set. The dump-bailer method was used in 106 shut-off operations and SG of these were performed at depths between 100 to 2000 feet. Table XIV has been prepared to show the relative number of shut-offs at- tempted by each method of cementing. These data are also segregated by methods of drilling. The last column shows the percentage of work, out of 702 operations, for each method. The percentages shown, under total, at the foot of tlie table confirm previous statements as to the excess of j-otary failures, namely. 7 per cent, over those of Cal)le tool drilling. 134 STATE OIL AND GAS SUPERVISOR.

The depths, already mentioned, for which dump bailer IS used, and the percentage of failures shown in Table XIV indicate that the limitations of this method have been fairly well determined. The failures for the Perkins method are higher than the average for all methods. The Perkins method was used in 63 per cent of all operations, and 78 per cent of the rotary operafions, listed in Talile XIV. Although one of tlie largest companies in the state contracts all of its cementing operations by this method, and a number of other companies use the method almost exclusively, it is probable that in a number of instances some other method, such as dump bailer or tubing, would have given better results. No matter how efficient or expedient a method of cementing may appear, it is the history of oil well operations that each new well presents a new combination of formational and mechanical conditions. It is hardly possible, therefore, to conceive of a method, almost auto- matic in so far as the attention of the operator is concerned, which can be applied efficiently in all eases. Results show that operators should make a more careful determination of the method of cementing necessary. The tubing method appears to be quite efficient for sliut-oflfs on rotary jobs. In the 24 rotary shut-otfs listed, 23 were made at depths greater than 2000 feet. Results for the Iluber & Wilson and Scott methods, although listed, po.ssibly do not warrant conclusions because of the relatively .small number of operations performed. THIRD ANNUAL REPORT. 135 %^m§mm:^: 136 STATE OIL AND GAS SUPERVISOR. FACTORS OF RESULTS OF TEST FOR WATER SHUT-OFF. The results of test for water shut-off, as between success or failure in excluding water, have been used in this discussion as the basis of con- clusions regarding the relative efficiency of the principal methods of drilling wells and shutting off water. Details of results of test an; listed in tables I to V inclusive under the headings Success and Failure. A study of these details will show that it is often necessary to identify a nund^er of factors, su-ch as drilling water, fluid levels, heaving for- mations, plug in casing, etc., before a definite statement can be made as to whether or not water is excluded at the shoe of the water string. The most positive result of test is one in which, if the hole is bailed dry, it remains dry for the period of test ; or, if it is bailed to a certain fluid level, there is no change in the fluid level during the period of test ; or, if water appears, the Avater is known to be coming into the hole around the shoe of the water string. The details of results already mentioned will show that such ideal tests are in the minority. Usually other extraneous factors appear in the result of the test or inspection incidental thereto. The factors have been divided by the writer into three groups, as follows: (1) Above the shoe. (2) At the shoe. (.3) Below the shoe. The diagram. Figure 7, on page 135, illustrates the arrangement of the various factors under each group. These will ])e discussed briefly, beginning with the group of factors above shoe. Factors Above Shoe. One of the factors above the shoe is that of water entering the well through leaky casing. Leaks in the Avater string are due to insufficient tightening of joints, collapse, or line wear — the last mentioned, rarely. A good example of leak in water string, due to insufficient tighten- ing, is covered in report of test at a well of the Associate 1 Oil Com- pany,^ Casmalia field. At the time of the first test water was entering the well from an undetermined source. The company ran a casing tester and found casing leaking at the rate of 670 gallons per day. The casing — 960 feet long — was screwed up 26 inches. . After the casing- was tightened, the tester, w'hen run to former depth, showed one pint of Avater in one-half hour. The size of the casing Avas 12^-inch, 40-pound. In AA^ell No. 38 of the Shell Company, Coalinga field,^ test of 10-inch. 40-pound, water string .shoAvcd 156 feet of Avater in 26 j hours.

Shut-ofE T 5-203, Sec. 14, T. 19 S., R. 15 E. THIRD ANNUAL REPORT 137 casing leak was found at a depth of 230 feet. The. casing — 192o. feet long — was screwed up 10^ inches, and test then showed 25 feet water in 16 hours. It is probable that this factor could have been more easily dctn- mined by bailing the casiug to a safe depth before the cement \\;is drilled out. A pressure test inside the casing will not prove as con- clusively as bailing whether or not the casing is tight, because it is possil)le to sustain pump ])ressure against a number of small leaks. Casing quite frequently collapses as the result of injudicious bailing. Any extensive tests to determine that a water string has collapsed are seldom necessary. In fact, when there is such a condition, uide.ss it appears feasible to swage the casing, the well never comes to a test. Collapse of unsafe lengths of r2^-inch. 40-pound casing has been noted most frequently. It is also noted that the collapsing strength of 12|-iuch. -iO-pound casing is 500 y)ounds per .square inch {see Table XV), the lowest collapsing strength of any size or weight of casing in connnon use. For example: tlie Doheny-Pacitic Petroleum Company^ in the (.'a.s- malia field lost a .string of 12^-inch. 40-pound casing through collapse. The casing was originally cemented at 1803 feet, and collapsed at 1440 feet upon bailing. In well No. 1, Quintero. of the Union Oil Company,- a water string of 12|-inch. 40-pound casing collapsed, after cementing and bailing, at about 1200 feet. The casing was swaged, but did not exclude water. In Darlington well No. 1 of the Petroleum Midway Company'' a string of 12i-inch, 40-pound casing was cemented at a depth f f 1821 feet. Fpon bailing to a depth of 1380 feet for test of water shut-off. the casing collapsed at a depth of 1500 feet. Because of the excessive length.s, nothing other than collapse should have l)een expected in the three cases mentioned. In order to overcome conditions such as the foregoing, where a long string of large size casing seems necessary, it is better practice* to use two weights of casing, putting the heavier weight casing on bottom. There appears to l)e no well defined rule as to the i-atio of combination of the two different weights. Table XV, giving the depths of water everting pressure enough to collapse, for various diameters and weights of casing, is taken from file First Annual Report.'' A factor of safety of at least 2, that is. dividing the figures in the last column of the table by l>. is n-com- mended. Soi^nS'^e.'c'!^ana"S; '''■^'■'"-"'" ''"■ «'^"'-"'^- ''^^'^ ^•^- ^-^5. Wei.

If conditions, such as danger from collapse, or heaving sands, or gas strata of high pressure, prohibit bailing dry, the well should be bailed to a depth at which there is several hundred feet difference betAveen fluid levels inside and outside the ca.sing. It is advantageous, for this reason, if for no other, to carefully record the fluid levels of Avater strata encoun- tered in drilling. It is difficult to make such observations in a rotary hole. Tu the last column of Table IV are shown a number of iu.stances in which fluid was bailed to a depth less than total depth to shoe. In each of these instances it was necessary for the inspector to satisfy himself that the depth bailed was greater than fluid level of water excluded. One of the commonest sources of small quantities of water in a well at the time of test is the minor feature called "drain-back." Drain- back is due to gravitation of water from bailed fluid sprayed onto the sides of the casing from leaky or ga.ssitig bailers, during preparation for test. It is difficult to compute the maximum amount of water THIRD ANNUAL REPORT. 139 allowable for drain-back. It depends upon such features as condition of bailer and tiuid, diameter and depth of casing. The following instance* will suffice, as one of many, for an example. A well in the Lost Hills tield was bailed dry for test. At the end of 17 hours 10 feet of water had colleeted in Ihc bottom ol' llie hole. This was allribnted to drain-back. Besitles spraying onto the sides of Ili«' ciising. bailed water connnoidy intermingles with oil, when present, and is held in suspension. It is sometimes necessary to thief the fluid, at increasing depths, to l)ottom and make centrifuge tests in order to determine whether or not there has been a change in the water content of fluid. This is illustrated in the following comments on test at M/C Well No. 37 of the Standard Oil Company, in Coyote Hills field.- On account of mixture of oil and water results of bailing tests at suc- cessively lo\ver depths did not show sufficient information to warrant a conclusion. Further tests at a later date were made. Oil and water were still considerably mixed. From the results it was not possible to conclude whether or not water contents of fluid had increased. Well was i)assed for pumping test and at end of 30 days tlie well produced only 0.4 per cent water. Another example is given in Report No. T 1-208 for Well No. 42 on the same property. The observations, taken from Deputy Supervisor Kirwan's report are as follows: "All free Avater had been bailed out. During the test the oil in the well stood near the surface. Samples of fluid from various depths showed a small amount of water and enudsion by centrifuge test. Approval to continue drilling was given. Reconnuended production test after completion." It is advantageous to know the nature of the water excluded as well as the fluid level. The advantages of chemical analyses of waters have already been mentioned in the discussion of the formation shut-off. There are other familiar advantages not within the scope of this discussion.' With reference to results at test, an elementary knowledge of the nature of the water excluded, such as whether it was fresh water. hrackish, salt or sulfur, is often sufficient for the inspector to determine the source of a water which may be present.

Tlic factcirs at tlu' shoe arise from failure to et a joli. Such failures nuiy be due either (1) to the nature of formations in which landing- was made; (2) impro])er ])re{)aratiou of the liole for shut-olT; (:i) ineffective placing- of cement. Ill uiaking a cement sliut-ofi:' the cement nuiy fail to set hecause of Kas agitation or a continuance of fluid circulation after cementing. In order to keep the gas quiet, the maximum hydrostatic head possible is held in the casing after cement is placed. This will also prevent differ- ential movements of cement fluid to a large extent. For the purpose of neutralizing the supposed luifavorable chemical reactions between certain native waters and cement fluid, compounds such as bicarbonate of soda or hydraulic lime are put into the well ahead of the cement in some instances. The necessity of this practice is (|uestionable. An example of this practice is .shown in shut-off operations of the Oak Ridge Oil Company* in the South Mountain field, Ventura County. In cementing a string of 12|-inch, 40-pound casing at 630 feet, the 75 sacks of cement used was preceded by 100 pounds of bicarbonate of soda. A few companies in the state use hydraulic lime in cementing opera- tions. The lime is supposed to perform a dual purpose. It is sent ahead of the cement and back of the casing in order to seal crevices and cleanse the exposed formations so that the cement can make better contact. It is also supposed to alter waters unfavorable to setting of cement and thereby hasten crystallization. There can be no chemical reaction between the lime and cement. The saturated solution of calcium hydroxide provided by the presence of the lime will facilitate the fonnation of calcium silicate crystals so as to make for improve- ment in the strength of the concrete. This, of course, applies to mixtures of lime and cement fluids.

")!' of the (Jeneral Peti'oleiim ('oiiipany in l^(dridg(! field, 15 feet of drilling water and 305 feet of oil entered the hole in 30 hours. This latter is a ca:se where th(! well had been drilled into the top of an oil stratum upon drilling out cement. The hydro-static head of the drilling water forced some of the water into the oil sand and it was I'eturned, upon hailing. Tn many cases where the hole breaks into an oil stratum, or where high pressure causes the oil confined below a thin crust to "drill itself in," a production test is the only recourse, other than l)ridging. A high pressure restricted flow of either oil or gas Avill, undoubtedly, hold water back. An instance- has been noted in which a flow of gas from a well, when unrestricted, allowed a flow of 700 barrels of water per day. When the hole has been drilled ahead into a sand stratum and water appears in considerable quantity at time of test, it is difficult to deter- mine whether the drill has entered a water stratum below the shoe or whether it is simply a case of failure of shut-off. In some instances the whole question of the success or failure in the development of a well, or even in' the development of a producing sand over an entire property"', hinges upon knowing definitely that the water alleged to be coming from a new sand below the shoe actually originated in that sand and not from around the shoe. The possibilities of a new water sand below the shutoff appear to furnish more uncertainties as to the condi- tion and prospective future of a drilling well than any other single fea- ture of operations. Providing that a sand is drilled into while prepar- ing the well for test, it would be a difficult course of reasoning, based upon bailing tests only, which would enable one to differentiate indica- tions and determine the source of water. If the water is not shut off at the shoe, this new sand, which the opera- tor pre.sently may propose to exclude with another string of casing, may be none other than the oil sand he is looking for. The complications here involved are illustrated by the following excerpt from transcript of a hearing* before the State Oil and Gas Supervisor relative to method of drilling wells in the Sunset PMeld. "Mr. Cotxom: INIr. Kirwan. I would like to ask you with respect to this question that has come up relative to the possibility of testing a sand immediately below a shoe of easing in which there has not been a shut-off. Do you think that it would be possible in ease you did not have a shut-oft' to definitely deter- mine what is the nature of that san^ immediately below that string of casing, that is, as to oil or water?

Mr. Collom : AY hat would l)e such a condition ? Mr. Kirwan: a. It would depend on the depth of the well, largely. I believe if you bailed the water ordinarily within two or three hundred feet of the l)ottom and it did not show up any oil, that there would be some probability that there was not an oil sand ; however, not conclusive evidence. Mr. f 'ollom : We will assume that you have not a shut-oft' and you l)ailed the hole and got water, do you think you would be .iustified in assuming that there was a water-sand? AIr. Kirwan : A. No, I don't believe you w^ould be .iustified in assuming it was a w^ater-sand unless you plugged between the shoe and the sand, and then after drilling out the plug if you got water you would assume that it was a water-sand. I don 't know any other wa>- hy which you could make that test except to plug inside of the water string up say about ten feet and then perforate alx)ve the plug, and if you didn't get water you could assume that the water was below the shoe of the water string. I am talking from an experience we have recently had in southern California, in which we demonstrated to the satisfaction of a company that the water which they claimed to be below the shut-off point was above the shut-off point by that method. Mr. Collom : What well was that, please ? Mr. Kirwan: A. We had Standard Oil— I believe Alurphy Coyote Well No. 31. Another case in southern California was one in which after a shut-off' was made above the oil sand, the oil filled up to within 120' or such a matter from the surface. And, in my opinion, this very test goes to show that it is necessary in many cases to have the water shut off before you know the character of the sand below the shut-off point." In addition to the foregoing. Avater .sands erroneously logged, or oil sands not logged, will interfere with all future engineering study of con- ditions on a property. 'I'his do(^ not mean that the operator should be any the less vigilant in liis efforts to detect and correctly log water sands. An in.spection of several thousand logs of oil wells drilled in California impresses one with the meagemess of this essential infor- mation. Bridge Below Shoe. As applied to this discussion a well is liridged below the shoe for one of two purpo-ses : (1) To form a solid seat, in contact with suitable formation, for cementing water string. (2) As a plug in the well al)ove oil. water, gas or other porous for- mations in order to determine if water is excluded at the shoe. 146 STATK Olli AND GAS SI IPIOKVISOK. lu eitlior case tlic liridi^c imisl he iiiiidc oT impervious niaterial, well bonded with forjuation, and oi' sufficient depth to withstand impact of heavy drilling, or heaving pressures h-oni below. Bridges are made of rock, cement, l)ricks, lead- wool or other niaterial. Bundles of wire line .should not be used. They are hard to drill out or sidetrack. The bridge should be at least 20 feet in depth, if thickness of suitable formations will permit. A solid and well l)()nded bridge will exclude all those sources of complication mentioned in discussion of factors immediately l)elow shoe. An illustration of a combination of both of these requirements of a bridge, and some of the deficiencies, is given in comments on reports on proposed operations and tests at a welF of the Doheny-Pacific l^etro- leum Company in the Casmalia field. The hole was bridged at 2460 feet to 2307 feet. Drilled out below 8:^-inch casing to test shut-oflf. Hole filled 2000 feet with water. Another bridge was placed just below- shoe of 8:^-inch casing in order to test for shut-off. Test not conclusive. Drilled out and made another bridge. Test showed small amount of water. Concluded that if water was coming through or around bridge it would increase in flow upon drilling out. This conclusion was proved to be correct. Water entered at rate of 89 gallons per hour before drilling. Fluid level at 9 :00 a.m.— 1700 feet. Started drilling at 11:00 a.m. At 12:30 p.m. fluid level was 1235 feet, showing that 465 feet of water had entered the hole during the period of two hours in which the bridge was intact and one- and a half hours after drilling started. This represented an average nf 370 gallons per hour for the three and a half hours, but the water came in much faster after the drilling was done. The average increase after drilling out bridge was 281 gallons per hour. Conclusion. The foregoing discission has developed the fact that, when water or oil, or both, move into the well during the period of test for water shut-off, the source of the fluid must be determined. The various source factors mentioned change from determinate to indeterminate, or the reverse, according to the extent and efficacy of drilling, bridging, plug- ging, or other operations conducted during the time the well is subject to test.

During drilling operations at certain wells of a group it frequently happens that there are marked changes in producing conditions at neighboring wells. In order to compare the effect of drilling wells upon the other wells a chart showing drilling progress will be found more convenient than written records. The chart here presented differs from those ordinarily used in engineering work in that it directly refers to distances from known strata rather than the ground surface. It therefore directly compares geological information with drilling and production data. Referring to the accompanying cross-section of a group of wells, (fig. 8) it will be noted that a line of correlation, "B." has been drawn across the top of the oil sands of the "second oil zone." This line defines tlie stratigraphy of the formations. With the idea of presenting a graphic history of drilling operations with respect to the stratigraphy of the formations penetrated rather than the respective depths below surface, a line parallel to the line of correla- tion B (see cross section) is assumed at a position below which the essential depths drilled can be plotted. The distance between the line of correlation and stratigraphic datum can be cho.sen arbitratily. In certain localities where some definitely known stratum or forma- tional marker exists — such as "Red rock." in the Coalinga East Side field, or "Bottom of blue shale." in the Casmalia field — the line of cor- relation of this stratum, in the various wells may be used as strati- graphic datum. When such a stratum, as the one referred to, exists in a group of wells, one progress chart can be made for the entire group, irrespective of their location. On the accompanying cross-section stratigraphic datum is drawn through zero depth, that is derrick floor at Well No. 6, so that all cor- rections for differences from surface to stratigraphic datum in each of the wells will be plus. In this position also the drilling records with respect to the principal upper water strata and other formations of importance can be plotted. . The data on the Progress Chart are shown with respect to time and depth. A convenient vertical scale is 100 feet to 1 inch. The depths drilled per day here shown would be unusual for anything but illus- tration. Progress in drilling is plotted from the daily tour records. It is not necessary, for plotting, to figure corrections between depths below surface and depths below stratigraphic datum.

CHAPTER III. LOS ANGELES AND ORANGE COUNTIES. By M. J. KiRWAN, Deputy Supervisor. Names of Fields. Operations requiring the attention of this office include eight developed oil fields lying within the boundaries of Los Angeles and Orange Counties. The name Whittier-Fullerton Oil fields follows common usage to include all fields east of the city of Los Angeles: namely Olinda, Brea Canon, Whittier, Coyote Hills, ]\Iontebello and Puente. In addition to the above the Salt Lake field located immediately west and the Newhall field about 30 miles northwest of the city of Los Angeles, are included in the district. Geology. The geology of the various fields in the district was covered briefly in Bulletins Nos. 73 and 82 and other publications of the State Mining Bureau. However, additional geological data which has been obtained since these bulletins were pulilished will be found under the divisions relating to the various fields in the following pages. General Statement. The entire production of oil in this district was produced by wells in Los Angeles and Orange counties. The data used in the following tables relative to number of producing wells and their production were taken from production reports filed by the operators with the department. The number of wells listed: number of producing wells: number of logs filed ; number of graphic logs ; average daily production of oil and water per producing Avell (for June 1918) ; percentage of water and number of acres of proved oil land, are shown by fields in Table 1. "Wells Listed" include new wells, welLs drilled and abandoned wells. TABLE 1. = 1 Number of wells accounted for by production reports..

The following table (Table 2) is a comparison of the number of wells actually producing; their average daily production of oil and of water; average daily production per producing well; and percentage of water, for all fields in the district during the month of June, foi- the last two fiscal years. Study of the table shows that there was an increase of 91 producing wells, and an increase of 29,578 barrels in the average daily fluid pro- duction, of which 28,236 barrels were oil and 1342 barrels were water, for June, 1918 over June, 1917. The table also shows that the average daily production of oil per producing Avell rose from 47.6 barrels in June, 1917, to 70.0 barrels in June, 1918. The percentage of water of the total fluid production decreased from 18.8 per cent to 13.8 per cent during the same period. Data similar to that in the foregoing tables are given under their respective fields in the following pages. It may be noted that there was little change in the number of producing wells and their production during the past year for all fields, except Coyote Hills and Montebello where there was a decided increase in the production of oil.

This is accounted for mainly by wells wliich were shut down in June, 1917. and others which were undergoing repaid during this month, and which were producing in June, 1918. There are some cases where companies failed to properly report nil wells pi-oducing until recentlv. 200 STATE OIL AND GAS SUPERVISOR. During the last fiscal year there was a decline of 11,987 barrels in the total average daily fluid production, of which 11,060 barrels were oil and 927 barrels were water. There was a decline of 13.2 barrels in the average daily production of fluid per producing well of which 12.0 barrels were oil and 1.2 barrels were water. The following table (Table 4) shows by fields the number of wells completed during the last fiscal year; the number of these wells actually producing in June, 1918 ; their average daily production of oil and water; the average daily production of oil and water per producing well and the percentage of water for this month.

It will be noted that the Salt Lake field shows a net gain of 24 pro- ducing wells for June, 1918, over June. 1917, though no new wells were completed in this field. This is accounted for by the fact, that certain wells which were idle in June. 1917 have since been placed upon the pro- ducing list and. in a few casc^. a failnre to properly report wells in the former year. 2()2 STATE OIL AND GAS SUPERVISOR. The following table (Table 8 shows a comparison, by fields, for the month of June, 1917, and June, 1918, of the relative amount of water produced by individual wells. The wells have been divided into three classes as follows : 0-20 barrels ; 20-40 barrels and 40 or more, barrels of water per producing day. TABLE 8.

In view of the test or tests witnessed, by the department, at each new well, it is i)r()l)able that the greater number, or nearly all such welLs i)roduce what water they nuike from sources l)elow the shut- off point. Frequently wells are drilled too deep so as to penetrate water-bearing formation below the oil measures from which it is desired to produce and have to be plugged near the bottom. Among the most difficult problems presented to the department is the supervision of wells penetrating water-bearing strata betAveen oil- bearing formations, for the purpose of producing from below the water. Such water is generally known as "intermediate" water. Cer- tain phases of this problem are dealt with elsewhere in this report. Graphic Logs, Peg Models and Cross Sections. A total of 1173 graphic logs have l)een drawn, or an increase of 29(5 graphic logs over last year. Nearly all of these logs were drawn in the San Francisco office of the department. During the last year "memo- randum" or advance copies of logs were received from nearly every company drilling new wells. Graphic logs of these wells were kept up to date by the local office, as the information was received, and were of much assistance in rendering decisions relative to proposed shut-off depths in new wells ; a total of 80 graphic logs are being so drawn. At the end of the fiscal year peg models had been constructed cover- ing 10,880 acres or 17 square miles. This is an increase of 9.200 acres over similar previous construction. Models have now been constructed covering practically all of each field except Brea Canon, Salt Lake and Newhall. ]\Iodels of these fields will be constructed as rapidly as possible. All of the models have been constructed to a scale of 100' to 1" and the more important portions of them set up in a special room IS' by 30'.'

Some of the other large companies, probably, will begin the constructiou of models in the near future. A number of companies, both large and small, use the models made by the department to secure estimates of depth at which water should be shut oflf in proposed wells and in some eases the depth to which wells may be safely drilled so as to penetrate as much oil formation as possible without encountering water below. A brief description of the value of a peg model and the method of constructing models which have been erected in the various field ofifices of this department is given on pages 64 and 65 of Bulletin No. 82, Second Annual Report of the State Oil and Gas Supervisor. Cross Sections. A number of cross sections have been drawn for use in supplementing data furuisht^d by peg models. In nearly every case the ci'oss sections vrere made by pasting graphic logs, in their true position, as to elevation and location, on tracing cloth and blue prints made. Further data as to methods employed to study underground conditions is given under the discussion of the various fields in the following pages. Method of Operations. In general, operators in this district have displayed a willingness to co-operate Avith the department to obtain accurate information relative to their wells. The department desires to see an improvement in the system employed by .some companies in securing and compiling informa- tion relative to the production of their wells. This information is of vital importance to the companies involved as well as to this depart- ment, as it furnishes the basis by which it can be determined whether a well is being profitably produced. In a few cases it has been necessary to call to the attention of a com- pany, inaccuracies in measurement of casing and depth of wells. As an example of this, a well in the Coyote Hills field, by the use of an incorrect sand line measurement, was reported to be 3646' deep with 8^" casing cemented at a depth of 3626'. At the time the test of Avater shut-of¥ was witnessed by this department, it was found that the casing was actually- cemented at a depth of 3649' instead of 3626' as reported, thus necessitating a change of 23' ^\■]^ch had to be appor- tioned in the log of the well. This error was caused by using a sand line measurement of 232' 6" in measuring the depth of the well, while the true measurement when measured by a representative of this department with a steel tape was found to be 234'. thus introducing an THIRD ANNUAL REPORT. 207 accumulative error of 1' 6" every time the derrick was "strung over." It is evident that a careful record of the casing put into this well was not kept, or the discrepancy of the measurement of the depth at which the casing was cemented would have been found. In the course of testing wells many interesting features have been observed. In several eases it was found that water was entering a well and the operator claimed the water was encountered in formations behjw the shoe of the water string. Subsequent tests demonstrated that the water was coming from above the shoe of water string. In some instances large quantities of cement were forced back of the casing and in one case in the ]\Iontebello field circulation to the surface liack of the water string was established. In one instance in the Olinda field, the owner of a well which was tested by this department claimed that oil- l)earing formations wliich had been penetrated below the shoe of the water string carried a certain amount of water, thus accounting for the water present in the well at tlic time of the test. To substantiate his claim lie cited the production of a neighboring well, the water content of wliich ccpialled the amount of water present in the well being tested. Upon recommendation of this department, a cement plug was placed below and extended up into the water string. Subsequent tests showed the same amount of water entering the well, conclusively demonstrat- ing that the water present in the well at the various tests was due to a casing leak. This trouble might have been avoided and the company saved considerable time and expense had a casing test been made previ- ous to drilling out the cement plug before test of water shut-off. It is the practice of some operators in this district to make casing tests on all wells previous to drilling out the cement plug in the bottom of the casing and the department desires to commend such practice, as results obtained at such tests have revealed the existence of a number of casing lealKAR Sir : Your well No. 1, Darlington, Section 81.

One well in the western part of the field produced nearly 1,100,000 barrels of oil and 13,000 barrels of water during the last 11 months. OLINDA FIELD. The major portion of the development work in this field was carried on during the fiscal year by the Union Oil Company and Petroleum Development Company. Eeference to Table 4 shows there were 13 wells completed during the year. Drilling was commenced on 17 wells. The production of all wells completed during the fiscal year amounted to 91.5 barrels oil and 16.2 barrels of water each per day during the month of June, 1918. Wells completed prior to July 1, 1917, made a total daily average of 6598 barrels of oil and 1250 barrels of water during June, 1918. This is a decrease for these wells of 1000 barrels of oil and an increase of 324 barrels of water for June, 1918, as against June, 1917. Wells completed during the fiscal year produced a total of 206,318 barrels of oil and 39,049 barrels of water during the year. The production for the fiscal year of wells completed prior to July 1, 1917, amounted to 2,703,103 barrels of oil and 393,850 barrels of water, making a total fluid production for the field during the fiscal year of 3,342,320 barrels, of which 2.909,421 barrels w^ere oil and 432,899 barrels were water. Table 8 shows 239 wells produced from 0-20 barrels of water, 13 wells from 20-40 barrels of water, 6 wells 40 or more barrels of water during June, 1918. Maps prepared by the department show that wells making 40 or more barrels of water per day are distributed throughout the field, excepting two localities, where there are a numljer of these wells in a group. Active repair Avork is in progress at one of these groups of wells in which an old Avell drilled several hundred feet beloAv present productive measures is being cleaned out and re-plugged. In view of the change in the system of one company in this field of reporting the amount of all water produced by their wells instead of the amount of water carried by oil in suspension after draining off the free water, there appears to be an increase of 407 barrels of water per day for this company. This accounted largely for the apparent increase in water of the total fluid production for June, 1918, as against June, 1917. There are other companies in this field who are still using this system and consequently fail to file correct production reports with the department. There has been practically no extensiuji of llic pi-ovi-d ai'ca in this field by wells completed during the fiscal year. Nearly all of such wells are located within the area eonsidered proved in the Second THIRD ANNUAL REPORT. 219 Annual Report. At present tliere is one well producing for every 5.3 acres of proved land in this field. As a result of recent study of underground conditions on the prop- erty of the Petroleum Development Company, in this field, one well which had been producing for approximately 17 years from a depth of 664 feet was deepened to 1465 feet and the production of the well increased from 3 barrels per day to 80 barrels per day. The gravity of this oil is 19.8° Baume and the water content amounted to only 0.26 barrels.

Table No. 1 sliows that there Avere 64 wells producing in this field during June, 1918. Tal)le 9 shows that wells completed prior to July 1. 1917, had a total fluid production during the past fiscal year of 2,275,823 barrels. Of this amount 1,614,068 barrels were oil and 661,755 barrels were water, or 29 per cent of the total fluid production was water. Only one well was completed during the past fiscal year and produced during June, 1918, a total of 1196 barrels of fluid, of which amount 1172 barrels were oil and 24 barrels were water, or the water amounted to 2 per cent of the total fluid produced. The produc- tion of all wells in the field during the fiscal year amounted to 2,277.019 barrels, of w-hich amount 1,615,240 barrels were oil and 6()1,779 barrels wore watei", or 29 per cent water.

Tliis is a decrease in the daily production of these wells as shown in June. 1917, of 513 barrels of oil and 202 barrels of water. Durincr June. 1918, there were 49 wells producing from 0-20 barrels of water, 4 .wells producing from 20-40 barrels of water, and 11 wells producing 40 or more barrels of water daily. There are two well defined areas in Section 2. T. 3 S.. R. 10 W., S. B. B. & ]\r., in which wells are seriously affected by water. One of these areas is located along the north line of the section in which 4 wells each averaged 73 barrels of water per day during June, 1918. The other area is located in the southwestern part of the developed portion of the section, in which area 10 wells each averaged 133 barrels of water daily during the same month. These two groups, comprising 14 wells, produced 87 per cent of all the water produced in the field during the month of June, 1918. The water condition of the affected areas has shown only slight improvement during the fiscal year, which would indicate that the water is being produced from water-bearing formations penetrated in certain of the wells and is probably not return drilling Avater, as was believed to be the ease by some of the operators in the field. This is further borne out by the fact that there was little drilling activity in the field during the past fiscal year. The large amounts of water used in wells being drilled or repaired could, no doul)t in some cases, be reduced by "mudding up" certain sands known to be very porous, thus reducing the amount of water used and consequently the amount of water allowed to enter the oil-bearing formations. Acting upon recommendations of this department, the Birch Oil Company successfully plugged the lower portion of their well No. 12 on Section 2, T. 3 S., R. 10 W.. S. B. B. & :\r.. and reduced the daily water production of this well from aljout 250 barrels to about 35 barrels and increased the daily production of oil from about 20 barrels to 35 barrels. The production of oil from this well will proliably be givatly increased when casing opposite upper oil sands. Formerly cased off. is l)erforated. Recent tests made of the prodnction of an adjoining well on this property show a eonsideral)le betterment in its water condition, possibl}' due to work performed on well No. 12.

PUENTE FIELD. The term Puente field, as used in this report, includes in addition to the known productive area of the old Puente field, located mainly in Sections 34 and 35. T. 2 S.. R. 10 W.. S. B. B. & M., in the Puente Hills, the western portion of the Ranclio La Puente, west of the town of Puente, upon which the Shell Company of California is operating. Actual development work was carried on in various parts of this field by the Shell Company of California. Petroleum Development Company, Copa De Ora and Gold Seal Petroleum companies. Up to the present time no oil has been produced by any of these new wells, the only pro- duction being reported from wells in the old field. Table 1 shows there were 44 wells producing in the month of June, 1918, all of these wells having been completed prior to July 1. 1917. These wells produced a total of 19,415 barrels of oil and 1838 barrels of water, or 8.6 per cent of the total fluid produced was water. The average daih^ production of this field for June, 1918, w^as 54 barrels of oil and 5 barrels of water. This shows a decrease of 8 barrels of oil and 1 barrel of water from the average daily production for June, 1917.

The average daily production of oil increased in this field from 852 barrels in June. 1917. to 16,985 barrels in June, 1918. Reference to Table 1 shows that there were 22 wells producing in June. 1918, and that their average daily production per well was 772 barrels of oil and 73.6 barrels of water. During the fiscal year there was a total fluid production of 3,477,672 barrels, of which 3,263,389 liarrels were oil and 214,283 barrels were water. One well, located in the N. E. j of Section 1, T. 2 S., R. 12 W.. S. B. B. & M., produced a total of 1,328,137 barrels of oil and 150,722 barrels of water, or a total of 40.7 per cent of all the oil and 70.3 per cent of all the water produced in the field. This w^ell was drilled 1675 feet below the first oil-sand, and probably penetrated Avater-bearing formation below the shut-off point. A number of wells have been drilled in the northeastern part of this section (Section 1), in which water above the first oil sand was shut off in the usual manner and imperforated oil strings landed from 700' to 900' below the first oil sand, probably mak- ing a formation shut-off. These wells were completed with a second, and in some cases a third, oil string so as to produce only from formations penetrated in the lower portion of the well. Clean oil has been obtained from all welLs finished in this man- ner. Such a procedure leaves considerable doubt as to protection of upper oil formations, providing intermediate water has been passed through and cased off with the upper oil sands. P^iture wells drilled in this area should be so planned as to locate, if possible, any inter- mediate water. This pos.sibly could be done by drilling the new wells deeper stratigraphically than the wells at present producing from the ]5-41«»4 226 STATE OIL AND GAS SUPERVISOR. uplxT foi-inntioiis and testing- by staj^cs, il: ncecssaiy, !<• tlw (l('|)lli li-nm which the present deeper wells are producing. In otlier words, test for probable inteniiediate water-bearing' formations between the upper and lower oil zones. It is possible that both the water and oil bearing formations are lenticular in shape, in which ease the water problem in this portion of the field will be difficult to solve and hard to handle, as in many cases it will be necessary to test deep wells before it will be known whether or not they passed through water. Wells completed in the north-central and northwestern portion of Section 6, T. 2 S., R. 11 "W., S. B. B. & M., have had very little water trouble up to the present time. Practically every completed well in this area is producing from all oil-bearing formations penetrated below the shut-off point. Several of the wells here have been drilled from 1200' to 1500'; and one well 1725' below the shut-off point. Production reports show that none of these wells make water. Three wells along the southern edge of the area just described average from about 20 per cent to 40 per cent water and emulsion in their fluid production. The source of this water has not been determined. Two of these wells were drilled 1132' and 762', respectively, below the first oil sand, while the third well was drilled only 700' below the first oil sand. All three of these wells adjoin wells drilled deeper, stratigraphically. and which produce large amounts of clean oil. The three wells under consideration are all on about the same contour, which suggests the possibility of an intermediate edge water, particularly in view of the production of clean oil from the adjoining wells up slope. One of the wells has been plugged to within about 600' of the top of the first oil sand without materially improving its water condition. Future developments should show whether or not the water in the three wells just described has any relationship to water penetrated in the wells mentioned in the following paragraph. Water was encountered in one well along the Standard-Union line in Section 1, T. 2 S., R. 12 W., S. B. B. & M.. after drilling 559' below the first oil sand. The lower portion of the well was plugged with cement and successfully excluded all water. Work is in progress plugging the lower portion of two other wells along this line in order to shut off water. The results so far attained in the area under consideration show that it is comparatively safe to drill wells about 525' below the top of the first oil sand without encountering Avater. In view of the wells drilled in this section which have penetrated various oil-bearing forma- tions from 1500' to 1700' below their shut-off point, it seems reasonable to assume that oil-bearing formations exist below the water penetrated by wells along the Standard-Union line, and the Avater penetrated in these Avells may ])e an intermediate edge winter. THIRD ANNUAL REPORT. 227 A well drilled in Section 2, T. 2 S., \{. 12 W., S. ii. U. & M., to a depth ol' 1J20' below the sliut-ofiF point has been shot in sevend i)laces and plugged with eemeiit up to within 650' of the shut-of¥ point. After tliis plugging the well avertiged about 300 barrels of oil and 100 j)arrels of water per day, indicating tliat the source of the water is above the top of the cement plug. In order to secure additional information as to the source of the Avater in this part of the field the owner of the well is drilling an adjoining well in which this company are i)lanning to drill to a lesser depth stratigraphically than the top of tlie i)lug in tlie former well and test by pumping, and later on, if necessary, possibly deepen in stages and conduct further tests. Two wells have been completed in the S. W. | of Section 31, T. 1 S.. R. 11 W., S. B. B. & M. One well Avas drilled 485' and the other 595' below the first oil-bearing formation penetrated. The former well averaged about 300 barrels of oil per day and 35 per cent water thirty days after completion. The other well produced mostly Avater when first tested and at present is standing with a cement plug extending 115' from bottom. Two wells have been completed east of the Rio Honda, in Section 6, T. 2 S., R. 11 W., S. B. B. & M. One of these wells was drilled 400' below the first oil-bearing formation and encountered Avater-bearing formation near the bottom. This Avell has a cement plug, extending about 100' from bottom, Avhieh shuts off the Avater. The other Avell Avas drilled 218' below the first oil-bearing formation and is producing clean oil. Results obtained in certain Avells drilled in this section immediately Avest of the Rio Honda, in AA'hich from 1200' to 1500' of oil-bearing for- mations Avere penetrated, indicate the possibility that productive oil formations exist beloAV the water in the Avell under consideration which has the cement plug in the bottom. "Water Avas shut off in one of the early Avells drilled in Section 6, T. 2 S., R. 11 W., S. B. B. & M. about 700' above the first oil formation. In vicAV of this the department recommended that the OAvner of the Avell stop drilling, and test the Avell before drilling below a specified depth. The result of the subsequent test showed that the Avell averaged over 50 per cent Avater in its fluid production. There is little doubt but that Avater from above the oil fornuition is entering the Avell as adjoining wells, down slope, drilled deeper stratigraphically are producing clean oil. The matter of repair of the well has been taken up with the oAvner Avho has been furnished the department's estimate of the depth at Avhicli water should be shut off. With a few exceptions, water was shut oft' above the fii'st oil-bearing formation penetrated in each Avell in the field. Operators Avere not required to shut off above, or protect from Avater, oil-bearing formations Avhicli the department considered of no commer- cial importance.

The information yivcn in tliis rci)()rt relative to water cniulitions in certain areas of the ^lontebello Field show that Avater is proving- a serious obstacle in the development of this field. In ordei- to sneeess- fully cope with this problem it will be necessary to do a certain amount of prospecting and testing. Such work should be systematically directed along proper engineering lines, taking advantage of study of peg models, cross sections, underground contour maps and chemical analyses of water produced by various wells. The department has a complete and up-to-date peg model showing a graphic representation of all wells completed and drilling in the field. Contours of the first oil-bearing formation penetrated by the various wells has been sketched on the boards comprising the base of the model. All property and section lines are also shown. A number of cross sections have been made and all available data on chemical analyses of water from Avells has been gathered. The responsibility of the future of this field rests largely upon the operators themselves, who in some cases, are not availing themselves of the benefits which would result from the employment of technical assistance. The gravity of the oil produced in the Montebello field ranges from 14 to 28 degrees Baume, inclusive. Wells producing from the lower formations penetrated produce the higher gravity oil. The gravity of oil produced by wells in Sec. 1 T. 2 S., E. 12 W., S. B. B. & B.. located along the Standard-Union line ranges from 17 degrees to 22 degrees, inclusive. One well in N. E. :j of Section 2. in the same township and range, averages about 15 degrees. The oil from wells, located in the northern part of Sec. 1 T. 2 S., R. 12W.. S. B. B. & I\l. and north western part of Section 6, T. 2 S., R. IIW.. S. B. B. & M., penetrating and pro- ducing only from upper oil zone ranges in gravity from 22 degrees to 25 degrees, while the gravity of oil produced from the ui)per zone by wells in Section 31, and east of the Rio ITonda in Section 6. T. 2 S., R. IIW., S. B. B. & M., averages about 19 degrees. Further study of the gravity of oil produced by avcIN in this field may throw some light on the water problem. History of Development.

Developments in the ]\tontebello field show that the top of the anti- clinal dome broadens out on its west plunge from its apex, near Standard Oil Company "Temple" well No. 3. in Section 6, T. 2 S., R. 11 W.. toward Standard "Baldwin" No. 4 in Section 2, T. 2 S., R. 12 AV. In view of this it is difficult to locate the exact top of the anticline in Sections 1 and 2. There are not a sufficient number of wells drilled on the east plunge of the anticline to accurately determine the exact direction of its axis. However, late drilling operations indicate that the axi.s of the anticline turns toward the south from its apex in Section 6. The average maximum dip of the developed portion of the south flank of the anticline near the center of Section 1, T. 2S.. R. 12W.. is about 20° with the direction of strike about S. 82° AV. as shown b>- the peg model in the office of the department. Surface dips of formations here range from 25° to 50°. There is evidently a steepening in dip of the south flank of the anticline toward the south line of Section 2, T. 2S.. R. 12 AV., as a well in the south east corner of this section has reached a depth of about 3100' without reporting oil bearing formations. The south flank of the anticline dips an average of about 30 degrees with the direction of strike about S. 72° AV. in the center of Section 6, T. 2S.. R. 11 A\^, in the developed area. AA^ells recently completed in Section 31. T. IS.. R. 11 AV., show that the north flank of the anticline dips about 35 degrees from the top of the anticline toward these wells. Results reported from wells drilling north of these wells in this section, show a still greater dip or failure of the upper oil-bearing formations to extend any consideral)le distance beyond the completed wells referred to. Results in general obtained along the north flank of the anticline indi- cate that this flank has a greater degree of dip than the south flank. The productive area of the eastern end of the field should l)e soon detei-- mined with the present rate of development. There is comparatively little activity in the western end of the field, the major portion of present work being along the axis and on the south flank of the anticline.

The total fluid production of this field during the year amounted to 1.902,772 barrels, of which 1,134,797 barrels were oil and 764,975 were v.ater. or 40.2 per cent water. Reference to Table 1 shows this field to have produced an average total of 2949 barrels of oil and 1,998 l)arrels of water per day during Juno, 1918. This is a decline of 487 Inu-rels of oil and 188 barrels of valci- pel- (lay dnriiii;- the fiscal year. No wells were drilled in tliis (iekl (InriuL;- llie year. The decrease in the amount of oil therefor represents llie natural decline in the production of the jjrodueing wells. THIRD ANNUAL REPORT. 235 A detailed description of work done in shutting off water pene- trated below the oil-bearing formations in Rancho La Brea Well No. 41, Sec. 15, T. 1 S., R. 14 W., S. B. B. & M., by the mud-laden fluid method, as recommended by this department, is given on pages 162 to 168, inclusive, in Bulletin No. 82, Second Annual Report of the State Oil and Gas Supervisor. After the water sand below the oil sand was entered and before the well was -mudded the water stood about 170' from the surface. A total of about 770 cubic yards of adobe and 50 cubic yards of sawdust were pumped into the low'er portion of the well, luider a pressure of about 400 pounds per square inch. Follow- ing the final mudding operation the well was shut down. A repre- Kontative of the department visited the well about three mouths after mudding operations had been completed and found that the water stood at the surface and that mud-laden fluid stood 140 feet from the surface. Salt Lake Oil Company wells Nos. 329, 330, 347 and 348 in Section 22, tidjoining Section 15 on the south, and Rancho La Brea Oil Company Well No. 38, were directly affected as each of these wells pumped a mud solution shortly after mudding operations were started in Rancho La Brea Well No. 41, necessitating the shut down of these wells, Avhile tlie mudding operation was in progress. These wells produced a total of 9,273 barrels of oil and 50,717 barrels of water, or 84.5 per cent water during a period of one year previous to mudding operations. The same wells produced a total of 24,669 barrels of oil and 47,588 ])arrels of water, or 65.8 per cent water for a period of one year follow- ing mudding operations on Rancho La Brea Well No. 41. This is an increase of 15,396 barrels of oil and a decrease of 3,129 barrels of water, or a decrease from 84.5 per cent water to 65.8 per cent, due, evidently, to work performed at Rancho La Brea Well No. 41, as imme- diately previous to work at this well the affected wells produced only .1 comparatively small amount of oil and a large quantity of water. Previous to the time that water sand was penetrated in Rancho La Brea Well No. 41, the above mentioned wells averaged approximately 70 per cent water in their fluid production. The water sand in Rancho Ija Brea Well No. 41 had been penetrated about 15 months previous to commencement of the mudding operations. Study of the foregoing data shows that Rancho La Brea Well No. 41 was not the principal cause of the water trouble in the adjoining Salt Lake wells. Table 8 shows that there were 236 wells producing from 0-20 barrels of walcr; 11 wells prodncing from 20 to 40 barrels of water and 20 weil.s producing 40 l);irii'ls or nioi-e watei- in I lie Salt Lake Held during Hie fiscal year. There w;is little change I'rom the i)r(n'ioiis y.-;ir in the nnnilx'r of wells producing tliese amounts of water. 2;3G STATE OIL AND GAS SUPERVISOR.

The work in this field was handled from January, 1918, to June, 1918, inclusive, by Irving V. Augur, Deputy Supervisor, located at Santa Paula, on account of the field being more accessible to the Santa Paula office. Records show that three new wells were eompleted in this field dur- ing the past fiscal year. These wells produced a total of 825 barrels of oil and 1994 barrels of water during this time, but as pointed out elsewhere in this report one of the.se wells produced in one month 1364 barrels of water, or 66.8 per cent of the total amount of water produced hy the new wells during the entire fiscal year. Wells completed prior to July 1, 1917. produced during June of lliat year an average of 362 barrels of oil and 325 barrels of water per day. In June, 1918, the average daily production of these wells was 326 barrels of oil and 362 barrels of water, showing that the average daily oil pi-oductiou of these wells decreased 36 barrels and the avei-age daily water i)roduction increased 37 barrels. The total fluid production of the field during the past fiscal year was 251,945 barrels, of which 119,289 barrels were oil and 132,656 l)arrels were water, or 52.7 per cent of the total fluid production was water. Talile 8 shows that 74 wells produced 0-20 barrels of water; 3 wells produced from 20-40 barrels of water and 2 wells produced 40 or more barrels of water daily. Tliis shows that there are comparatively few wells ])roducing large amounts of water. The water production (liiriny- June. 1918, amounted to 4.6 liarrels and the oil production was i.l barrels per well per |)r(i(liiciiiL; (\;iy (hiring lliis iiKinth.

Dominguez Field. During the fiscal year notiees of intention to abandon 3 of the 4 wells commenced the previous year, were received. One well in this field was drilled with a rotary to a depth of 5000' ; Sy casing was landed in this well at a depth of 3970'. No oil-bearing formations were reported as having been penetrated. One of the wells abandoned w'as drilled to a depth of 3449' and the other to 1622' without finding oil. An effort made to develop gas in the Highland Development Companj' well failed on account of not being able to shut otT' water. Inglewood Field. A well was drilled in this field by the Bartolo Oil Company to a depth of 4500' and the well plugged and abandoned without develop- ing oil. Newport Field. Drilling was commenced on two wells in this lield durinj; the latter part of the fiscal year. One of these wells, owned by the Standard Oil Company, is located on Section 14, T. 6 S.. R. 10 W.. S. R. B. & M., and is about 500 feet northwest of the U. S. Collins Well No. 3. whidi reported oil at a depth of 2525'. The Collins well was never .satis- factorily completed on account of water trouble>i.

THIRD ANNUAIi REPORT. 243 A zouc is eousideird "doubtful" whoii a shut off lias hocn )uad<' below it without afterwards demonstrating that it has l)een protected. A zone is considered "unprotected" when water has not been shut off above and tested, or when a well i)roduces from it and makes con- siderable water. The term "intermediate water" is herein used as meaning water between the first and second zones, or second and third zones. The position of "intermediate" water in relation to the zones is given in each case where used. The term "edge water" is herein used as meaning that water indigenous to the down slope portion of an oil stratum which, as the oil is removed from the stratum, follows up the slope and replaces the oil. The term "top water" in all cases means water above the first zone. The term "bottom water" is not used in this report, except to quote from company records. Study of the table shows that there are comparatively few wells in which certain zones are known to be protected and that the majority of them are in the "doubtful" class. Probably a number of "doubtful" zones will have to be placed in the "unprotected" class when the pres- ence of "intermediate" water has been established. Possibly some of the zones in wells in the "unprotected" class produce water which enters through the oils and from neighboring wells. GEOLOGY. In general, the structure of this property is a monocline, which is the southward dipping flank of the main Whittier anticline, which is terminated to the north of this property by a fault zone between the Fernando and Puente formations. It is important to note that the zone of crushing Avliich is in evidence along the fault zone to the north, does not extend into the flanks of the monocline on this property. On the contrary, the structure is a simple monocline, and study of a peg model and cross-sections reveals con- formity of underground structure to surface exposures. Three distinct oil zones have been penetrated in drilling on this property'. It is worthy to note that zones as reported in log records furnished by the company are fairly uniform. By application of information already obtained these zones may be anticipated at uniform stratigraphic depths in new welLs to be drilled in this territory. The monocline structure is slightly complicated by a flexure, or anti- clinal fold in the monocline, the direction of the axis being approxi- mately N. 20° E. and transverse to the strike of the bedding i)lancs of the formations in the center of Section 26, T. 2 S..

The water produced possil)ly comes from sands between the second and third zones. Well No. 31. This well was completed February 5. 1915. There is no evidence at hand to show that the tirst zone has been protected from water. The shul-ofV point in th<' well is lielow the first zone and above the second zone. The well was di-illed into the third zone. Assuming that the shiit-otf is (^ff'ective (cemented with 7 tons) then the water which is |)i'odiiced |)rol)al)ly enters the well through the second or third /.ones, or from between these zoii(\s 254 STATE Olli AND GAS SUPERVISOR. Well No. 32. Tlie sluit-oir point is Ix-low Iho first zone. Tlic well avjis drillcnl into the third zone. Records from the company show that the well was plugged with cement and lathe turnings from 3046' to 2970' and failed to shut off water. Test of -water shut-off witnessed by this department on September 13th, 1915, showed that water Avas not shut off and the following recommendation was made : "This well may be pumped for 30 days from date to demon- strate if water is shut oft'. At the option of the company, during this time, a new plug may be put in or the water string tested." Additional plugging has not been done to date. The log shows that 8-|" casing landed at 2957' above the point to which the well was plugged. Evidently plugging Avas done in the formati&ti, below the casing. The records do not show if any sidetracked casing was left in the well below a depth of 2957' which might act as a con- ductor of water. The well was plugged at the bottom in sand. The 10" casing which was cemented Avith 10 tons of cement probably prevents the downward passage of water below a depth of 2139'. Probable "intermediate" water from between the second and third zone may be entering this well. Well No. 33. Study of the peg model and log record indicates that the 12|" casing was cemented below the first zone. The log gives no record as to the effectiveness of the shut off with the casing. The 10" casing was cemented above the second zone. Records filed do not show manner or result of test of water shut off. The well was drilled into the third zone and produces from both second and third zones and averages nearly two barrels of water to one barrel of oil. Probable "intermediate" water between the second and third zones may be entering the well. Well No. 34. The shut-oft' point is below the first zone and above the second zone. Record of results of test of shut off are not shown on the log. The well averaged 130 barrels of oil and 115 barrels of Avater per day during August. The source of water in this well probably is the same as other "third zone" Avells in the vicinity, "intermediate" Avater or possibly Avater entering the Avell through the second or third zone. Well No. 35. Drilling Avas commenced August 24, 1915. The first zone Avas shut oft', the shut-oft' point being aboA'e the second zone. The test of shut off with 10" casing was witnessed and approved by a member of this department. The well Avas drilled into the third zone and completed March 22, 1916; hoAvever, the March production report shows it producing 31 days THIRD ANNUAL REPORT. 255 during this month. It is important that the prochietion of oil and water be reeoi'ded immediately after the completion of n well. 'Vhv. production report showed the amount of oil produced but not the amount or percentage of water until June, 1916, when the report showed the well making 2.4 per cent water and, the month following, as making 45 per cent water. At the request of this department, the company checked the June production with their field records and found that tlie well averaged 254 barrels of oil and 180 barrels of water per day, during June, 1916. Probably the 10" casing is still preventing the passage of water below the cementing point (2208'), indicating that the source is from the second or third zone or "intermediate" water from between them. During August, 1917, this well i)rodueed considerably more water than oil. Well No. 36. Dnlling was commenced October 18, 1915; 12^" casing cemented at 1720', above the first zone, but failed to shut oft' water. Notice of test of water shut-off was not filed and test was not witnessed by this department. Drilling was continued and 10" casing cemented at a depth of 2351', helow the first zone. The first test made by the com- pany after cementing, showed that water was not shut off. The 10" casing was re-cemented with tubing by pumping in 1^ tons of cement. Test of water shut-off Avitnessed by a member of the department showed that water was not passing to lower levels in the well. The well was drilled into the third zone. The log record states that "bottom" water was encountered somewhere between depths of 2351' (Avater shut-oft' point) and 3228' (bottom of well). The well was pumped from April 15 to ]\Iay 7, 1916, and according to the record made a large amount of water with a slight showing of oil. Production of this well was not shown on production reports until June, 191G. FoUow- ing is the record given. The barrels of water was computed by this department from data on the report.

At ])resent the well produces about six times as mucli water as oil and [xjssihly allows a large (piantity of water to enter both the second and third oil zones. In view of the amount of work don(^ at this w(^ll and its serious water ( cndition, it would seem advisable to clean out or redrill, if necessary, to a depth of about 8110' : shoot and ]ilug with cement in the formal ion between the following depths: .S0!)0' and 3110'; 2905' and 3015'; 2880' and 2900': 2650' and 2670'. P:aeh cement plug put in should be allowed to stand at least 24 hours and a determination made that ( ement has set properly before doing further work. The space between the cement plugs should be tilled with clay or cement. Test should be Tiiade, pumi)ing preferably, after each cement plug has been put in. While the I'ecoi'd shows that all casing above a de{)th of 2529' has l)een withdrawn from the well, it would seem advisa])le to shoot between depths indicated above in order to shoot together one or more open holes that possibly have been sidetracked during the various plugging, re'plugging and redrilling operations. The failure to shut otit' water in this well after a year's work should )te sufficient evidence to prove that it is not advisable to drill wells below the second zone until such time as the water situation can be effectively handled. Well No. 37. Study of the peg model indicates that the horizon of the first zone i!iay begin at 1600'. where sandy shale showing oil was encountered, or with the "sandy shale showing oil" encountered at a depth of 1816'. This latter shale is reported as 33' in thickness and has been shut off with 10" casing cemented at 1874'. Test of water shut-off witnessed by this department shows the balance of the first zone was protected from "top" water. The well was drilled into the second zone.

There is apparently a typographical error in the log, which shows the well completed, Sepiemher, 1916. as production report is shown for April of same year. The 8^'" easing (oil string') is landed about the center of the second zone and is not perforated. The present 6{-" oil string is perforated through the second zone only. It would seem advisable at this time to make an etfort to locate the source of water entering the well and carry out necessary remedial work in order to protect both the first and second zone from water. Study of production of wells in the neighborhood show that clean oil may be produced from either the first or the second zone, individually, as follows : first zone, Weils No. 43, No. 45 ; second zone, No. 44. Study of the record of this well indicates that the source of water is local and probably is ''intermediate" water from between the first and second zones or po.ssibly from below the second zone. Well No. 38. Drilling was commenced December 2], 1915. The company proposed to shut off water at a depth of about 2050', estimating that producing oil sand should be encountered at 2100'. This proposal received the approval of this department. 17-41894 258 STATE on. AND GAS SUPERVISOR. TJie first /(tne wa.s I'jiconnlcred at a dcptli of 1420'. No provi.siou was made by the company to ])rotect this zone; 12A" easing was carried through it and "lauded" at a depth of 1617'. Water was shut off in the well immediately above the top of the seeojid zone and test approved by this department. The well was drilled 540' below the top of the second zone, entering water-bearing formations and possibly the top of the third zone. After drilling was completed, the well produced at the rate of 500 barrels of water per day. The record indicatas that ihe oil string was withdrawn and the bottom of the well plugged up to 2070' with cement, brick, rope and gravel. The work at this well definitely showed two things: (1) that water- bearing formations are present below the second zone; (2) that the second zone does not carry water at this well. The records do not show whether or not the hole was plugged from 2518' to 2070' in one operation. This leaves the question of exact depth of source of water undecided except that it is between limits of 2518' and 2070'. Well No. 39. Drilling was commenced February 22, 1916. It is interesting to note at this time that the company estimated in their notice of intention to commence drilling, that water should be shut off at a depth of 2100' , and that approval was given by this department to shut off at this depth, also that the well was completed at a depth of 2099' . No provision was made by the company to protect the first zone from water as 12|" casing was "landed" below this zone. "Water was shut off immediately above the second zone and well was completed July 21, 1916, making an average of 330 barrels of clean oil per day and no water, proving that the the second zone is very productive and free from water. The present daily average of this well is 289 barrels of clean oil and no water. Well No. 40. Drilling Avas commenced April 22, 1916. The company estimated that productive oil sand would be encountered at a depth of 3000' and proposed to shut off water at a depth of 2200', or 800' above where oil sand was expected. The log shows that the well was completed at a depth of 2035', or nearly 1000' above where it was astimated the top of oil sand should be encountered. Estimates of this kind are confusing and are of no value to this department. The company Avas advised that the local representative of the department could not be present at the test and requested them to test the Avell themselves and file Avritten report. This was done and test approved in our decision No. C-89, dated September 27, 1916. The well Avas completed August 29, 1916.

This well has been drilled into the lirst zone only. The in-oduction shows that the first zone is eapable of producing a sufficient amount of oil to -warrant definite protection from water in this and other wells penetrating this zone. Study of the production record indicates that water ma>' not be completely shut off or that the first zone carries water at this location. This water may possibly enter the well from adjoining wells, numbers 25, 32, 35 and 36. all of which are "third zone" wells, completed and producing large amounts of water at the time this well made its initial production. The log shows gravel from I960' to 1995' and shale from 1995' to 2035'. The water condition of the well may possibly be improved by plugging from 2035' up to about 1950'.

Notice of intention to commence drilling was received April 20, 1916. This well is located near the northwest corner of Section 26, and there is some doubt as to the exact depths at which the various zones were encountered. Study of the peg model indicates that the first zone was encountered at a depth of 1145' ; at which depth first oil-bearing forma- tions are recorded in the log. Ten-inch casing was cemented at 1916', or 16' below the top of the oil sand encountered at a depth of 1900'. The results of test of water shut-off showed that water was prevented from descending to lower level in th(^ well. The shut-off point was below the first zone and probably into the second zone. Records from the compan,y state that the well was drilled to 2103' and 8^" perforated casing set at 2087', and well pumped 3 days, exhausting drilling water and oil.

With the well in this condition, the company proposed to put in the 4^" casing, make pumping test and deepen. Approval was given only to clean out to 3048' and test by pumping. (See our Deci- sion No. CC-282 of May 26, 1917.) This decision states that further recommendations Avould be made after the well had been tested by pumping. In answer to a request for information, the following letter, dated October 24, 1917, was received from the company : "'In reply to Avork done in M-W Well No. 41. since vour Decision No. CC-282 of May 26, 1917 : On same date Decision CC— 282 was sent to company, production was discontinued.

Will have log in duplicate on regular form at early date." The AA^ell produced 16 days during August, 1917, and made a daily average production of 16 barrels of clean oil and 214 barrels of Avater. The outstanding feature of Avork at this Avell is that the first zone was shut off and probably not protected from Avater. The second zone pro- tected from Avater above it. The test of 3 days Avas not sufficient to adequately demonstrate the productiveness of this zone. IIoAvever, it did shoAV that the second zone does not carry Avater at this aa'cU. Study of peg model and log records indicates that the top of the third zone probably begins at a depth of 2500' and that the upper portion of this zone has been shut off Avith 6|" casing cemented at 2882'. The company did not sul)mit a proposal or receive approval of this department to cement perforated 8|" casing at a depth of 2851', beloAV the second zone. Notice of test of water shut-off Avas not reeeiA''ed. The results of tests made by the company shoAved that this casing failed to shut off Avater. Study of the results of this test indicates that "inter- mediate" Avater was encountered between tlie second and third zones, TIIIKD ANNUAL REPORT. 2fil or that possibly tlic upper portion of the third zone carries water. A proposal was not received to cement the 6|" casing at 2882'. nor notice of test of water shut oft' when the cement jol) was tested. The letter of October 24 from the company, quoted above, shows that our decision No. CC-282 was ignored and the well deepened fi-um 204^8' to 3276' with water not shut off. Work of this kind only serves to complicate matters. Recent developments at adjoining Well No. 47, which produces clean oil from the third zone, show the necessity of tests to determine the source of water entering the well, and that repair woi'l\ is iiccessai-y to protect the various zones from water. Well No. 42. Notice of intention to commence drilling was received A])im1 20. 1916. The company estimated that productive oil sand should be encountered at a depth of about 2900'. Water was shut off with 10" easing at 3587' and the top of the first zone encountered at 1600'.

The company stated that this casing Avould be cemented to pre- vent water that. might be encountered from entering either the upper (first zone) or lower sand (second zone), and to keep heavy oil out of second zone. Accordingly 8|" w^as cemented at 2111'. After receiving approval of test of water shut off', the well was drilled to a de|)th of 2298' and the well completed in the second zone. The results obtained show that first zone w^as free from water at this well and yielded an average ])r()dnction of 34 barrels of oil i>er day for days which the well was pum|)ed. although it appears to have been difficult to operate the well on account of sand trouble. Probal)ly the well would have produced more f)il if the first zone was penetrated to a greater depth, as the deepening record showed that oil sand continued for 34 feet below the depth at which the well was tested.

The percentage for July is shown as 79, and should be 7.9. This has been confirmed by a letter from the company. The production of oil obtained from the first zone at this well is sufficient to warrant its protection from water in future wells drilled on the property. Well No. 44. Notice of intention to commence drilling was received June 6, 1916. Approved proposed depth of water shut-off. "Brown shale .showing oil" was penetrated between depths of 1885' and 1905'. Study of the peg model indicates that the first zone was probably encountered at a depth of 2045' ; however, there is some question as to whether or not the top "Brown shale showing a little oil" should not be taken as the top of this zone. Ten inch casing was cemented at 2042' and the well drilled 38' ahead of the shoe of this casing and apparently bailed dry.

The well was then deepened to 2701' (into the second zone) and pumped from January 6 to February 15, 1917, averaging about 10 barrels of oil per day. During this time trouble was experienced with heaving sand and considerable water had to be run in when cleaning out. The Avater condition of the well was not definitely determined, although the production reports show tliat the well aver- aged about 50 per cent water while pumping. The well was bridged from 2620' to 2560' and 8^-" casing cemented at the latter depth. Test of water shut-off was witnessed on April 9, 1916, and the following decision rendered: "Data at hand indicates that the 8j" casing which was cemented at a depth of 2560' shuts off' formations which are productive in adjoining wells, and damage from water may be ensuing. This casing was cemented without the approval or knowledge of this department. The test indicates that possible water above a depth of 2560' is prevented from passing to lower levels in the well. I recommend that the company test the well by pumping or bailing above a depth of 2701', pending further recommendations." The Avell was deepened from 2701' to 2743' and at present is pro- ducing from the second zone. During August of this year the well averaged 113 barrels of oil per day and no water, showing that the second zone is free from water and that water evidently was present between the first and second zones. Work at this well demonstrated the failure to produce clean oil from both the first and second zones simultaneously. Well No. 45.

The well was drilled into the first zone only, and during August, 1917, averaged 44 barrels of oil and 2 barrels of water, daily. Probably all of the first zone has not been penetrated by the well and the production may possibly be increased by deepening. In case The company decides to deepen, it would be well to do so in stages of about 50', in order to locate possil^le "intermediate" water below the first zone and above the second zone.

Drilliug Avas started December 21, 1916. The company proposed to shut off water at a depth of about 1600', nnd estimated that productive oil sand should be encountered at a depth of about 1700'. This department recommended that company shut off water at about 2000'. The following letter, dated January 3, 1917, was received from the company in reply to this decision: "Kindly refer to your letter to me under date of December 27th, and vour report on proposed operations, dated December 29th, No. CC-183, both relative to the drilling of M-W No. 46. You state that you think it advisable to shut off Avater at 2000 feet. We know there is a heavy oil sand above this point at about 1700 ft. and therefore would recommend shutting the water off at about 1600 ft., as stated in our notice of December 13th. We would endeavor to shut this water off Avith the 10" casing and test out the heavy oil sand at 1700 feet. If AA^e Avere unsuccessful in shutting off the water, and the quantity of oil obtained Avas not sufficient to Avarrant us continuing producing from this sand, Ave would shut off the water at 2000 ft. with 8:^" casing and complete the Avell in the loAver sand Avith 64" casing. Kindly adAdse me as soon as possible, your recommendations in this matter." This department replied on January 8, 1917, as follows : "Yours of January 3d relatiA'e.to Murphy- Whittier No. 46 to hand. Note what you have to say about heavy oil at 1700 ft. If you think this is Avorth testing out, it Avill be all right to shut off Avater at about 1600 ft. and make the test, but I think it is A-erA^ bad policy to change your shut-off point back to a higher level, and would not recommend your drilling into the lower sand until you have shut off Avith the 8^" at about 2000 ft.

Study of records filed by the company indicates tliat the fir.st zone was not tested to determine its productiveness.

On August 10 the compauy replied to this report, stating that no reason was found for shutting oft' at 1800' and that there were no indications of oil until a depth of 2134', where "brown shale, light showing of oil and gas" was encountered and continued to 2154', and that similar conditions prevailed at 2271'-2288'. The following state- ment was made in this letter: "In cementing 8^" casing at 2377', sufficient cement — 200 sacks — was used to go up behind the casing and protect from water formation logged 'light showing of oil' ". No mention, however, was made a])out the protection of the second zone in which "oil sands" were logged and shut off. No definite evidence has been presented to show that the second zone has been protected from water. The well w^as drilled to a depth of 2645' and produces from the lower portion of the third zone.

The following is a part of our Report on Proposed Operations, writ- ten April 23, 1916 : "Herewith please find data on Standard Oil Company's wells in the area adjoining this well. These data show that the water condition of some of these wells is serious. Records at hand indicate that two oil zones should be penetrated in this well. The upper sand carried heavy oil and possibly some water in tlie down-slope portion of the sand. The upper zone should be protected from water until such time as it is definitely proven that this sand carried water. Therefore I recommend that the company protect the upper zone from top water, and if water develops in the well from the upper zone sand that the lower zone sand be protected from this water. The accompanying data show that water has not been shut oft" at a uniform stratigraphic depth in this area, indicating that this fact is tlie cause of some of the water trouble in this section." The company carried out the first part of our recommendation and shut off water above the first zone M'ith 12,|" cemented at 1521'. Test of water shut-off was approved.

The well was drilled to a depth of 2312' and put on the pump September 23, 1917. A letter from the company states that the well averaged 221 barrels of oil and no water during the last 7 days in September. Study of the log record and peg model indicates that the upper portion of the second zone was shut off with 10" casing. There are no records at hand to show that tests were made to determine the pres- ence or absence of "intermediate" water between the first and second zones. The production record shows that the second zone is free from water at this well. Well No. 49. Drilling was commenced ^lay 3. 1917. The company originally pro- posed to shut off water at a depth of 2160', and amended the notice by proposing to make an additional shut-off at 1400'. This depart- ment recommended first shut-off at about 1500' and approved the second shut-off point at 2160' as proposed. The log shows that the top of the first zone was encountered at 1686'. AVater was shut off with 12|" casing cemented at 1687'. Test wit- nessed and approved on August 15. 1917. On August 21 the follow- ing letter was written to the company : ' ' Our report on test of watei' shut-off, No. T 1-14, dated August 15. 1917, approved test of water shut-off with 12^" casing cemented at a depth of 1687', in Murphy-Whittier well No. 49, Section 26, T. 2 S., R. 11 W. Our decision No. CC-305, dated June 12, 1917, approved proposal to make additional shut-off at a depth of about 2160' in order to protect the second oil zone. There appears to be no definite evidence as to the presence or absence of a water-bearing fonnation. in the area adjoining this well, between the first and second oil zones. Since recent wells drilled in this area make shut-offs above both of these zones, we think it would be advisable to thoroughly test the formation be- tween 1687' (shut-oft' point) and 2160' (proposed shut-off point) in order to determine the kind and volume of fluid contained in these formations. Thi.s information should be of nuich value in j>]Hnning future shut-offs above the first and second oil zones. We would appreciate having your view.s in this matter." No reply to this letter has been received and suggestions contained therein have not been carried out. The manner in which the company ignored this letter suggests that more positive action than merely writ- ing letters, .seems necessars- in matters of this kind. The well reached a depth of 2235' October 30. and drilling w;is lieing continued. 2G8 STATE ouj and gas supervisor. Well No. 50. Notice of intention to eomnience drilling was received April 2, 1917. The company estimated that productive oil sand should be encountered at a depth of 2500'. The proposal to shut off water at 1950' was approved. Drillinu' was commenced May 25, 1917. A supplementary report (Ml depth of water .shut-off was made by this department on August 11, 1917, as follows: "A study of our peg model, showing development work sub- sequent to the i.ssuance of our decision mentioned, indicates that water should be shut off in the neighborhood of a depth of abo\it 3 750', providing an oil sand is not encountered above this depth." There is some question as to the depth at which the fii^st zone was encountered. The top of this zone may begin at 1465', where "sandy shale showing a little heavy oil" wa-s encountered, or it may begin at a depth of 1687' Avith "Brown sandy shale showing a little heavy oil"; 10" casing was cemented at 1641', but failed to shut off water. The company succeeded in getting circulation around this casing and pumped in three tons of cement under 800 lbs. pressure. The well stands re-cemented at this time. The drilling so far shoA^'s that careful work has been done and that the company is endeavoring to protect the tirst zone from Avater encountered in this well. Well No. 51.

Drilling was commenced August 23, 1917. The proposed estimates of depth of water shut-off and depth at which the first zone should be encountered has been approved by this department. GENERAL SUMMARY. The following wells were completed prior to December 1, 1913, when the property Ava.s taken over by the Standard Oil Company: Nos. 1, 2, 3, 4, 5, 6. 7, 8, 9. 10, 11, 12. 13, 14, 15, 16, 17. 18. 19, 20, 21, 22, 23, 24, 25, 26, 27 and 28. Wells Nos. 4. 9, 10 and 27 had been abandoned by the IMurphy Oil Company. The index map on the diagram of wells shows the location of Old Nos. 13, 16, 17 and 19. which were also abandoned by the ]\Iurphy Oil Company. In general, the logs and histories of the old wells drilled by the Murphy Oil Company are very incomplete, due, perhaps, to the lack THIRD AXXIAL REPORT. 2fi0 of foresight <»1' the rormcr uwner.s to kci'\) necessary records. Oii aeeouut ol" the liick of j)roi)er recoi-ds and the sei'ions water condition ol* mauy of tlie ohl wells, the Standard Oil ('ompany was eonfruiit; l1 with problems which appear to liave been retlected into hiter wells drilled. Study of records tiled here fail to show that any remedial work wa.s done by the Standard Oil Company to eliminate water troubles in the old wells, except to abandon No. 26 and No. 28. Some of the present water trouble may be due to deterioration of casing, allowing water to enter them through the water string. Probably the greater part of the trouble is due to ineflfeetual methods of shutting ot¥ water and lack of knowledge of geological conditions in shutting oflf at proper depths. The production report for the month of August, 1917, shows 38 producing wells. Twenty of these welLs were completed by the ^Murphy Oil Company, and ])r()duced 14,926 bai-rels of clean ail and 33,630 bar- rels of water; out of a total of 73,709 barrels of oil and 70.755 barrels of water i)rodiiced by all the wells on the property. Accoi-ding to these figures, the wells drilled by the ]\Iurpliy Oil Company averaged ]()81 barrels of water, each, and welLs drilled by the Standard aver- aged 2063 barrels of water, each, during August. Wells drilled by the Standard Oil Company produced 37,125 barrels of water, which amounted to 52.4 per cent of all the water produced on the property during August. It would seem unlikely that the cement .jobs in the new wells would have failed to the extent of allowing so much water to enter these wells, or that the old welLs should be the cause of the major portion of this trouble. Therefore it would seem reasonable to assume that the source of the water is either through the various zones, or "inter- mediate" water between them. The following record of wells tends to show that the varions oil zones penetrated do not carry "edge" water and that the .fourcf of jnost of the water produced by the various wells is "inlci-niediate" water from between the oil zones. The following wells produce from the firet zone only : Wells Nos. 40. 43 and 45. The combined production of these wells during August was 4523 -barrels of oil and 687 barrels of water. These wells averaged le.ss than eight barrels of water per producing day. They may be affected In- water from ad.joining welLs. or make their own water resulting from inetfectual shut-offs. Well No. 45 averaged le-s than two barrels of water daily, and since this well is deeper stratigraphically than either No. 40 or No. 43, it suggests that the cause of the water condition of the latter wells does not result from "edge" water. 270 STATK Olli AND GAS SUPERVISOR. The following woUs produce from the second zone only: AVells Nos. 23, 38, 39, 42, 44, 46 and 48. No. 48 was completed September 23, daily average 221 barrels of oil and no water. Reference to "]\Iap showing average amounts of water produced daily by various wells in August," Fig. 10, shows that all of these wells are shown in "yellow." Reference to similar map showing "oil" produced. Pig. 11, shows that they are among the best producers on the property. These wells produced a total of 27,845 barrels of oil and 5 barrels of water during August. The figures show absolutely that the second zone does not carry "edge" water in present area drilled. These wells are fairly well distributed over the present proved area of the prop- erty. Special attention is directed to the fact that wells Nos. 44, 46, 42, 39 and 48 are among the farthermost producing wells, down the dip of the formation, and should be first of present producing wells on the property to show "edge" water from the second zone. The following wells were drilled into the second zone and there is some question (on account of shut-off and perforation record) as to whether they produce from the first zone, in addition to the second zone : Wells Nos. 21, 22, 24 and 37. Of these Nos. 21 and No. 22 produce only a small amount of water and oil. Wells No. 24 and No. 37 produce relatively large quantities of water and oil. By referring to "Summary of evidence at each well," it will be noted that there was some question as to the effectiveness of water shut oft' above the first zone in well No. 24. The depths of these two wells l^elow the second zone suggests the possibility of entrance of water from below this zone. It is possible that water may enter them from between the first and second zones. Adjoining well No. 44 may have been troubled with water from the same source, before shutting off immediately above the second zone, which work cleaned up the well. The production of wells producing from the first or second zone indi- vidually indicates that the source of water is not through these zones. Therefore the source of water must be above them or below them. The water condition of these two wells shows the necessity of determining whether or not there is an "intermediate" water between the first and second zone. Attention is again called to the letter from this depart- ment dated August 21, 1917, to the Standal-d Oil Company, suggesting tests at well No. 49. These tests were not made. Study of the peg model and cross section indicates that the following wells penetrate the third zone : Nos. 1, 2, 3, 4, 5, 6, 7. 8, 11. 12, 13. 14, 15, 16, 17, 18, 19, 20, 25, 26, 27, 29, 30, 31, 32, 33, 34, 35, 36, 41. (Forty-seven was drilling during August.) Of these wells, the ones shown in symbols and colors on the maps, "Average amounts of ivater and oil produced daily by various wells in August, 1917," see Figs. 10 and 11, produced during August. THIRD ANNUAL REPORT. 271 The oiilstaiidiug feature of llic "wntev" map is that every well shown in Red, exeept No. 37, products fi-om the lliird zone. Recent developments at well No. 47. in which water was shut ott' above the ma.ior portion of the third zone shows that this zone is free from water at this well, and shows further that "intermediate" water was encountered between the second and third zones. Study of the records indicate that the first zone has been shut otf iu all of these wells, exeept, possibly, No. 25. in which the record is not entirely clear. Therefore, it appears that the source of most of the water produced by "third"' zone wells is between the second and third zones, or pos-sibly through tlie third zone in its down slope portion. The log records show only two wells (13 and 19, drilled by Murphy Oil Company) in which water-l)earing formations are reported below or between any of the three oil zones. In view of this and the number and distribution of wells producing large amounts of water, it seems that the former policy of drilling wells on this property should be changed so that water-bearing formations may be definitely located and recorded in future wells drilled, which penetrate these formation.s, in order that necessary remedial work on present well may be instituted and carried out in the proper manner. On account of the large amount of water produced by wells on this property, it will be necessary to put in plugs and conduct certain tests to secure information relative to exact location of water, which should have been obtained at the time the wells were drilled. It is remarkable that practically every well which produces from one zone only, produces clean oil, indicating that the earlier wells drilled are not responsible for the bulk of the water trouble on this property, as has been generally supposed by people not entirely familiar with the condi- tions as they actually exist. RECOMMENDATIONS. Recent developments show that the j)i'operty ott'ers many possibilities in the amount of recoverable oil and wai-rants the expenditure of con- siderable money in adeciuately protecting the various zones from water. (1) Water should be shut otf abort the first zone in each new well drilled, particularly along tlie southern and western edges of the present producing areas. Three wells are now producing connnercial (piantities of oil from the first zone only, in this area. New wells drilled farther south and west may find increasing quantities of oil in this zone, at greater relative depths. The policy of protection should be pursued until it has been demonstrated that tlu' first zone "pinches out'': carries "edge water," or is barren of oil. (2) Possible water-bearing formations should be located betweini first and second zones. This should he dcme in deepening by stages and testing. 'J (2 STATE Olli AND OAS STTPKI{VIS01{.

(Tlic main sonrcc of jlic pfe.scnt watci- trouhlc seems 1o be; between second and third zones.) (4) In the future, wells should not be drilled into the third zone until the "intermediate" water between these zones can be prevented from entering either the second or third zone. (5) Suggestions made in ' ' Summary of evidence at each well ' ' regard- ing plugging lower portions of wells 24, 37 and 40 should be carried out as a matter of initial tests to determine, if possible, source of water entering these wells. (6) The production of oil from the following wells probably does not paj' for their maintenance and operation : Xos. 2, 3, 5, 6, 12, 12>, 15, 19 and 22. No. 12 and No. 13 produce large quantities of water. The water condition of the property probably would be improved by properly plugging and abandoning all of these wells. (7) The water situatioQ could be greatl}^ improved by shutting oft" water in wells Nos. 25, 32, 34, 35 and 36. Possibly this could be largely accomplished by eft'ectively plugging these wells between the second and third zone. (8) The condition of well No. 41 shows the necessity of immediate repair work. (9) The depth at which fluid stands and amount of tubing in each producing well should be determined and used in a manner similar to the ' ' Creme case ' ' at Coalinga. (10) Chemical analysis of water from wells which produce water may serve a purpose equally as useful, in determining source of Avater as at Coalinga. (11) The value of perforation record has been pointed out in a num- ber of cases in the report and extreme care should be exercised by the company in keeping record of perforation of oil strings. (12) A definite system should be worked out between this depart- ment and the Standard Oil Companj^ for protection of the various zones penetrated, with the use of the least amount of casing necessary. (Pos- sibly this may mean the introduction of the mud-laden fluid method of drilling new wells, which penetrate more than one zone. This may best be accomplished by a meeting of representatives of the Geological and Producing Departments of the Standard Oil Company with repre- sentatives of this department in our Los Angeles office at an early date.

CHAPl ER IV. VENTURA COUNTY. By Irving V. Augur, Deputy Supervisor. This district was fonnerly under the supervision of M. J. Kirwan, Deputy Supervisor of District No. 1, with offices in Los Angeles. Tlie writer took charge of it in Decenil)er, 1917. It was found, upou taking charge, that the greatest need of the dis- trict, outside of routine tests and reports of well operations, was a more tliorough undei'standing of underground conditions and structure in the vai'ions fields. It should he borne in mind that, unlike other dis- tricts in the state, the productive areas in Ventura County are scat- tered from one end of the county to the other, and that each producing area, of which there are approximately thirty-five, presents entirely dif- ferent underground conditions, due to the individual structures upon which they are located. For this reason it became necessary t<> study each individual area separately, and the liest prelimiiuiry method to such study was appar- ently through the construction of peg models. Consequently attention was first paid to the larger producing areas, and the following peg models erected : (1) South Mountain field. (2) Bardsdale field — Bardsdale dome. (3) Simi field. (4) Ventura field. In addition, the following are partly completed: (1) Bardsdale field — ^Iontel)ello dome. (2) Pico Canon field. Since th(^ construction of these models, many instances have occurred which have proved their value in anticipating the depths at which oil and water-b( ariiig ioi-mations should be encountered and the pr(>per depth of shut-oti'. Similar residts liave been obtained from the use of undci-ground contour )iiaps. but it has been f(mud that the peg model is more easily and fpiickly uuflerstood by the majority of operators in the field, and, if properly constructed, is as accurate as the contour map. In one instance the peg model proved more useful and accurate than cross-sections made by an engineer of one of the companies. In this case, the troulile lay in the proper correlation of certain cross-sections and the im|)i-o|)er correlation i)i oth(M' sections, due to the impossibility of forming a mental picture of the sub.struct ore of the entii'c prodncing area. THIRD ANNUAL REPORT. 315 ^Faiiy conipanics operatinir on small production niijjlit increase the amount of production materially upon thorough analysis and knowledge of the structural conditions. Losfs of approximately 300 wells have been filed during the past year. The number of logs now on tile for the district is more than double the number on file for the i)revious year. Out of the total num])er of logs li.sted for the comity, only Ho per cent have so far been filed. This number, however, includes logs of a great many wells drilled and aban- doned years ago. The logs of most of these old wells have been lost or destroyed. (Jraphic logs drawn nmnber 311. The total production of the county for the fiscal year ending July 1, 1918, amounted to 1,646.839 gross barrels of which 1.126,183 barrels was oil and 520,656 barrels was water. The proportion of water, therefore, for the county wa.s 32 per cent. According to monthly production reports field in this office, the amount of oil produced during the fiscal year exceeded the amount of oil produced during the preceding year by about 230.000 barrels. There was also an increase in the Avater pro- duced, amounting to approximately 265,000 barrels. The proportion of water produced with the oil for the county has risen from 27 per cent in 1916-1917 to 32 per cent in 1917-1918. The production per pro- ducing well per day, during the year, was 9.3 barrels of oil and 5 barrels of water, as against 7.9 barrels of oil and 3.1 barrels of water for the year previous. Case of People of the State of California vs. Thomas A. Slocum. During the year it l)ecame necessary to file complaint against Thomas A. Slocum, due to the failure of Slocum & Company to file logs of wells drilled on its i)roperty on Sec. 21, T. 4 N., R. 21 W., S. B. B. & 'SL. Santa Paula Oil field, and for failure to file monthly pro- duction reports, notices of intention to drill new wells, notices of inten- tion to abandon, redrill or deepen old wells, and for failure to notify the department for test of water shut-oft' before finishing and complet- ing new wells. After repeated eiforts, in writing, on the part of the state deputies to obtain the necessary information, and the entire disre- gard by the company of these requests, the above mentioned complaint was filed by the District Attorney of Ventura County. The defendant entered a denuirrer. which was not sustained. In the meantime, all of the desired records were prepared by the Com- pany and submitted to this office. This department thereupon requested that the ease be dismi.s.sed. This action is in line with a similar action brought again.st the Providential Oil Company, in District Xo. 1. and reported on pages 127 and 128 of the Second Annual Report (Bulletin No. 82). 316 STATE OIL AND GAS SUPERVISOR. Early History of Operations in Ventura County. According to a report by Professor Silliinan published in 1865, the presence of "tiuid intiaminable sul)stance" was known in California as earl}^ as 1792. For many years the presence of petroleum on the surface was regarded as a detriment to the property because of the lo.ss of live stock, which became mired in the pools of petroleum. Various reports indicate that the Indians in the region for many years used the petroleum occurring in the numerous seepages, in the same way as the Indians made use of the petroleum in the Pennsylvania oil fields previous to the development of oil. As early as 1854 there are records of the development of petroleum by Mexicans in this region. It is said that the Mexicans erected a still, with a copper worm, from which illuminating oil was made. In the year 1861, George S. Gilbert, a San Francisco man, erected a refinery for handling oil on a small scale. The refinery was built at what was afterwards known as Camp No. 1 of the California Development Company. The supply of oil came from natural wells or seepages, from which he is reported as having obtained 400 barrels of oil, without apparently diminishing the supply. The principal product of the refinery was illuminating oil. Gilbert's venture was considered a success until his plant was destroyed by fire. It was rebuilt, but a second time burned to the ground. The work was then taken up by the Philadelphia Oil Company, the Hayward Company, California Develop- ment Company, T. R. Brad, Stanford & Company, and others. In all, six camps were established by the California Development Company, located as follows: Camp No. 1 was situated on the property of the Arnaz family, later known as the Ferguson place, in the southwest corner of the Rancho Ojai, on the old Ojai Creek Road. It was at this camp that oil opera- tions were first started by Thomas R. Bard, upon his arrival from Pennsylvania. A house was built here for Mr. Bard, which in recent years has gone to ruin. Camp No. 2 was situated clo.se to the site now occupied bj^ Camp Comfort, being about a mile south of the town of Ojai on the San Antonio Creek. Here one well was drilled on the property of P. T. Hobson. Camp No. 3 was situated in the upper Ojai Valley. Camp No. 4 was established on the Rancho Ojai in Pinkerton Caiion. Camp No. 5 was situated near the head of Saisar (See-saw) Creek. Camp No. 6 was near Camp No. 5. A number of wells which were drilled in this camp, and known as the "Astarta" wells, are now oper- ated by the Pyramid Oil Company. In a published rejiort, made by S. F. Peckham in June, 1866. is found llie statement thai, during the course of ten months. ;?()()() hbl. of oil T11IKI> ANNIAT, REPORT. 317 had l)('(Mi sliipixd from the Ventura oil Melds. The ««:ivatei- part of this prodiK'tioii came from tiiiiiiels and seepajies. and the operators were conservatively advised to follow this line of develoi)meut, although there were a few wells produein^' small amounts of oil at this time. In 1877, the Standai'd Oil Comi)any was operating on the Santa Ana Raneho, in the Cafiada de Los Coehes. and also in Santa Paula Creek, north of Santa Paula. In the same year, Adams, Thayer and Edwards were oi)erating five tunnels, ten wells, and several springs in Adams Canon; and Saxby. Davis and Remington were drilling near the eastern end of Sulphur ^lountain. Acknowledgments are made to Messrs. (iidney, Brooks and Sheridan's "History of Santa Barbara, San Luis Obispo; and Ventura Counties," and to Professor Silliman's "History of Recently Discovered Regions in California," for information on this subject. AVith the advent of the Ilardison & Stewart Oil Company, in 1883, operations in this district received a decided impetus. The principal developments were carried on in the Rancho Ex Mission, Sespe Creek, and later in Torrey Canon. The combination of Ilardison, Stewart and Bard interests, by which the Union Oil Company was foi-med. develoj)ed further interest in active drilling operations, and placed the county first in point of pro- duction in the state in the early days. The Hardison and Stewart interests which entered the Union Oil Company were the Hardison & Stewart Oil Company and the Sespe Oil Company; the Bard interests being represented by the Torrey Canon Oil Company. The organiza- tion of the Union Oil Company took place in 1890. Subsequent to these early developments, the attention of oil men was diverted from the Ventura oil fields ; but in recent years the attention of the oil prospector has reverted to this county. During the past two years a inunber of discoveries have added materially to the importance of this county in respect to production of oil. Among the new dis- covei-ies may be mentioned the South Mountain field, with a daily pro- tluction of (i(l() bbl., and the Ventura field, with a daily production of af)pi-().\imately 200 bbl. of oil. The lattei- field includes two producing areas, the first being \'entura field proi)ei', in which the Shell Company of California, the (Jeneral Petroleum Corporation and State Consolidated Oil Company are represented, and the other area being about five miles south of O.jai. in which the Xew Mexico Oil Company and IT. L. Hayes are operating. As contrasted with the early developments, recent developments have been undertaken upon later ideas of geologic structure. The result has lieen a considerable increase in the amount of production from the coiintN. A nuiiilxM* of ina.ioi- structural features, beneath which lie .ni8 ,ST.\TE OIL AND (i\9i SliPERVISoH. roi-malions wliicli are oil-l)earin,(>' in other parts of the county, still remain uiiprtjspected in this field. Quite reeeutly these have l)een attracting consideralih' iiitci'est aniouu oil operators, and it is i)rol)ahle I hat the prodiietion for the eounty will l)e increased. For the sake of convenience, tliis district has been divided, and will be considered under the following named fields : Piru, Simi, Bardsdale, Sespe, South INTountain. Santa Paula, Ojai.

Reeords show seven producing companies in this field during the past year; three companies beinir located north, and four south, of the Santa Clara River. With one exception, each opt rating company in this field obtains its production from separate and distinct anticlinal folds, and the under- ground conditions governing the accumulation of oil and water are, therefore, distinct and noneommunicating. A feature of remarkable interest, from the standpoint of geology and the influence of under- ground structure upon accumulation, is evident upon the property being developed by the Diamond Valley Oil Company. Upon this property a plunging anticline from a westerly direction develops into a marked overturn tranverse to the axis of the anticline. It is possible that wells drilled in tliis area have penetrated one stratum from two to three times. Water Conditions.

BARDSDALE FIELD. The Burdsilalc field incliulcs Iwo distinct iuitielincs and productive areas. In the eastern edge of the iield, the Montebello anticline is being developed by the Montebello Oil C-ompany. Calumet Oil Company, and TTome Kaneh Petroleum Company. The Bardsdale Dome, on the west- ern ed^e oi* the field, is being developed by the Union Oil Company, l^ardsdale Crude Oil Company and Bell Oil Company. The daily production from the Montebello Dome amounts to 1514 bbl. of oil and 119.4 l)bl. of water, or 7.8 per cent water. The daily production of the Bard.sdale Dome amounts to 83.6 bbls. oil and 6.1 bbls. water, or 6.8 per cent water. The production of the field as a whole, during the year, amounted to 579.136 bbl. oil and 45,188 bbl. water, or an average of 7.2 per cent water. A comparison with production figures in the Second Annual Report shows a decrease in amount of oil produced of approximately 1 bbl. per producing well per day, and an increase of .4 bbl. water per well during the same period. The decrease in the amount of oil pro- duced is probably accounted for by the decrease in drilling operations. Three new wells have been drilled during the fiscal year, as compared with nine new wells the year before. New Developments. Reference to Table V shows that the three new wells in this field were drilled by the Calumet Oil Company, Montebello Oil Company and the Petroleum Midway Company, Ltd. The results of drilling by the first two named companies will not materially increase the productive area of the field. Should the new well being drilled by the Petroleum Mid- way Company, Ltd., prove productive, the proved acreage between the Monte))ello and Bardsdale domes will be largely increased. During the past year six wells have been abandoned, as compared with three wells the year previous. Five of the wells abandoned were situated on the Bardsdale Dome, and the work of abandonment is a forerunner of the further abandonment of wells in the field on a larger scale, due to the extremely low production of wells on the edge of the field. Construction of Peg Models. In order to better understand untlerground conditions in this field, a peg model of the Bardsdale Dome has been completed by this depart- ment, and a peg model of the Montebello Dome is in process of construc- tion. The peg model of the Bardsdale Dome shows a simple dome structure, the apex of the dome being approximately on the line between Sections 1 and 12, T. 3 N.. R. 20 W., S.B.B. & M. The direction of the axis is idmost east and west. TJIIKI) AXM.M, KKI'OKT. ^'2'^ Extent of Productive Oil Horizons in the Bardsdale Dome. From (lata as shown hy the jx'jj: iiioilcls. it is evident tliat must of the prodnction np to the i)resi'nt time in the Bardsdale Dome is derived from an oil horizon approximately 400' in thickness, and is obtained clcse to the apex of the fokl. Wells on the edge of the field are now idle, or have been abandoned. It is noticeable that certain wells drilled in the western portion of the field have enconntered and are producing from an oil horizon which overlies the main productive horizon and outcrops before reaching tlie apex of the fold. The oil is of a compara- tively low gravity, and considerable water is produced with the oil, oil and water being frequently reported as occurring in the same sand. Several wells in this area have been deepened to the main productive horizon, increasing very materially thn prodnction and gravity of the oil. Extent of Oil Horizons in the Montebello Dome. The division of this area into three oil and two water zones has been described in tlie Second Annual Report, Bulletin No. 82. A third salt water zone wa.s encountered l)elow the third oil zone mentioned in this rcpoi-t. Foi' a considerable time it has been recognized that the firet oil zone in this area is not as extensive laterally as the second oil zone. The first zone is not productive east of the line between Sections 3 and 4, T. :i X.. R. 19 W.. S.B.B. & ^1. The oil sands of this zone are encoun- tered in the area, but have been found to contain no oil. It has been the policy of companies which have drilled through this top productive oil horizon to land a water string below both the oil horizon and the first salt water zone, and immediately above the second oil zone. This policy may be found, in the future, to be responsible for considerable water trouble in the first oil horizon, which is productive in wells to the west. It may. at some time, be necessary, on account of the prohibitive amounts of water, to change the depth of water shut-off in wells which have penetrated both the first oil and first water horizons, or to gradually abandon the shallow wells now producing from the top oil zone. The aiuount of water entering the top oil zone has increased 23 per cent from November, 1916, up to June, 1918. A definite policy should be adopted in drilling new wells in this area, looking towards the mudding and protection of the top oil zone in all new wells drilled. Not only is the first oil zone nonproductive in the eastern portion of this field, but several huiulred feet at the top of the second zone are non- l^roductive. Original })lans for shutting ofl" water in this area called for a uniform statigraphie shut-off above the .second oil zone, irrespec- tive of the productiveness or non[>ro(luctiveness of the top portion of this zone. Recently the tendency has been to carry water from the first salt waliT zone into tin- nonpi-odnct ivc portion of the second oil zone. S24 STATE OIL AND GAS SUPERVISOR. Tlie ivsults of such a policy, if contiiuiod, may introduce water trouble, which may not for the time heint? l)e noticeable in adjoining wells. This policy should be discouraged unless the portion of the oil zone to be cased ott' has been fully protected from top water. Another feature of interest is the discovery, on the eastern edge of the field, of the existence of probable edge water in the lower portion of the second oil zone. Several wells having encountered this probable edge water have been plugged back ostensibly as having encountered the third salt water zone. One well which encountered this probable edge water has l^een deepened farther into the oil zone to obtain greater production, and is now producing considerable water from the edge water sand or sands. This condition must be anticipated in future drilling in this area and .steps taken to prevent the infiltration of water into the oil sands in any well to be drilled or already completed. A co-operative spirit must prevail in all operations in order that the water problem may be handled efficiently and the danger from infiltration avoided. At the present time water conditions are not serious, but the source of po&sible water trouble must be recognized and future operations be guided by definite protective policies.

Kentuck Lease, Sudden & Emslie, Mutual Oil Company, Rose THIRD ANNUAL REPORT. 325 Oil Company, Union Oil Company and White Star Oil Company. Many of the wells located in the npper portion of the Little Sespe Creek were amcng; the first producing wells in Ventura County. A great many of the wells have l)cen abandoned on account of .small ])roduction. On October 2. 1!)17. a disastrous fire swept over the northern portion of t\\v field, which (h'stroyed many rigs, houses and tanks. Of the twenty-six rigs so destroyed, otdy ten have been rebuilt. Su))se(pient to the fire, the production was approximately 1700 1)1)1. ])er month, of which only about 1100 bbl. per month have been recovered. New Developments, Only one well was started during the past year. This well is on the property of the Big Sespe Oil Lease, in the group of wells which mark tile northern limit of productive territory in the Big Sespe Creek. Two wells have been abandoned. Very little development has taken place in this field during the fiscal year, and but slight, if any. progress has been made, due principally to the forest fire which laid waste such a large portion of the northern part of the field. Production and Water Conditions. A comparison of the present production figures and those issued last year shows the daily production of oil per producing well to be practi- cally the same. A considerable decline in water is shown, however; and no area of excessive water production was reported. The total amount of oil produced by the field was 30,845 bbl.. and the total amount of water 6165 bbl.. the water production being 9.4 per cent of the gross production. Future Developments. As almo.st all of the productive areas, and the prospective productive areas, in tliis field are located some distance from shipping points, and the only road to the district is a wagon road which is practically closed to travel during the wintei- nu)nths. and, furthermore, since the produc- tion obtained is small, and the producing areas and folds are consider- ably limited, further extensive devel()|>ments dui-ing the coming year are not anticipated. Future reports of this district will un(h)ubtedly show a decline in operations undeilakeii and pi'oducl ion. ratiier than an increase. 326 STATE OIL AND GAS SUPERVISOR.

Since the completion of the first well in this field in April. 1916, twenty-one additional wells have been completed or are drilling, and the field has risen from fifth plaee to second place in point of produc- tion in the county. During the fiscal year the daily production from this field amounted to 591 bbl. of oil and .3 bbl. of water daily, as compared with 134 bbl. oil and .4 bbl. water for the previous year. The daily production per producins' wells was 65.7 bbl. of oil, as com- pared with 6.5 bbl. of oil per producing well in the Bardsdale field, which has the largest total production of all other fields in the district. Such a comparison gives an idea of the production which may be expected of this field in the near future. A large proportion of the production was obtained from wells which fiowed oil while drilling. If the present rate of progre-s ditains for the coming year, it is not improbable that the field Avill produce apju-oximately two-thirds as niucli oil a.s the Bardsdale field. Up to tliis time no Avater-bearing formations have been discove'vd above the top of the first oil horizon. Drilling oi)erations are, there- fore, much sim[)ler than under the conditions encountered in the Monte- bello Dome of the Bardsdale field, where salt water zones have been reported. Geologic Formations and Structure. The slructui'e of this field is anticlinal. It is very similar to the Bardsdale Dome, of which it is a eontiimation to the west. The larger production is obtained at the ai)ex of the fold, which plunges both THIRD ANNUAL REPORT. 327 easterly and westerly. The dip on tlie north tiank i« considerably steeper than that on the south flank. There is a possibility that the dome is slightly overturned to the north. From surface indications it api)ears that the axis of the anticline, as it plunges westward, sepa- rates into two axes, which diverge and finally disappear under the lloor of the 8anta Clara River Valley, south of the town of Santa Paula. The southerly branch of the anticline may turn towards the southwest, parallel with the foothills on the south side of the river. Recent drilling in the productive area in this field has been confined solely to beds of the Sespe formation. Wells which were started in these beds have been drilled to a depth of 3000' without encountering the Tejon shales, which probably underlie this area. Beds of later age than the Sespe, which in this area include the Vaqueros, Puente and Fernando, have been eroded from the apex of the fold and swing around the plunging end of the axis several miles to the west of the dome. They are, therefore, unimportant as oil producing formations in the present producing area. New Developments. At the present fimc. in this field, there are foui' wells drilling, whicii will no doubt determiiu^ the extensiveness of the pool along the axis of the anticline in an easterly and westerly direction. Comparing the structure of this field with the structure of the Bartts- dale and ^lontebello domes, which are a natural extension of this anticline towards the east, it seems probable that the limits of the production of the field will be nuu-h more restricted than has been generally conceded liy the operator-'. It is very probable, as men- lioned above, that the first oil horizon is less extensive than the lower oil measures, and it is also possible that edge water will be found in various sands of the lower oil formations. The ])roductive area will probably not exceed one and a half miles along the axis and one-half mile transverse to the axis at the apex of the dome. In an attempt to develop formations which at one time carrii'd oil .Mid outci'op near the crest of the mountain, one well was drilled very dose to the axis of the syncline which parallels the South Mountain Dome. It is claimed that the oil sand which .showed on the surface, nnd which is probably of Puente Age, was encountered at a depth of about loOO', but that the sand did not carry oil at this point, nnd the A'.ell was tlierefore abandoned.

An extension of the field towards the west is a possibility. Similar areas further west along the Fernando- Monterey contact, and located in the Ventura field, have recently received a good deal of attention and have developed a considerable quantity of oil. Production and Water Conditions. The production for wells in this field is less than any field in this district, amounting to 2.7 bbl. oil and 1.3 bbl. water per producing well per day, or an average of 34.3 per cent water. The production of the field shows a decrease of approximately one-half barrel of oil per day, as compared with the production of the previous year, the amount of water being practically the same.

Since the acquisition of exteiusive property, formerly owned by the Bard Oil and Asphalt Company, in this field, l)y the Pan-American Petroleum Company, considerable new developments have been in progress during the fiscal year. Three new well.s were started by this company, two of them bein": located in producing territory, the third seeking to open up new areas a])out two miles west of the main lease. The latter well, known as "Pinkerton" No. 1. is drilling close to, and south of. prolific .seepages which occur at the outcrop of oil strata, which at this point cro.s.s Pinkerton Canon and dip 65° toward the south. The completion of a commercially productive well in this locality would undoubtedly prove up a large portion of territory in the western and southern part of the field. Great importance is attached to the completion of a well drilled l»y the Great Republic Oil and Paint Company, near the south line of Sec. 8, T. 4 X.. R. 21 W.. S.B.H. & .M. This well was drilled only a few hundred feet from a well on this property drilled in 1902 by the Xorthern Oil ('(mipany. which well was carried to a depth of 1460' and was producing six barrels of oil per day nine years later. Both of these wells enter the Tejon formation at the surface some distance north of the fault which marks the southern limit of the Santa Paula ridge and which has been considered as defining the northern limit of producing territory. The Te.jon shales at this point are dipping approximately 45° north and gradually assinn.- an almost vertical ])osition before reaching the fault to the south. These wells are apparently the only wells which have obtained |)r(>dii(tion directlv 830 STATE OIL AND GAS l^UPERVISOR. from tlic Tejon formation in this field. The presence of oil in this lofality where the oil bearing formations, from which the wells produce, outcrop a short distance to the south, and where no seepages occur, may he due to one of the following reasons : 1. The hardness and compactness of the Tejon oil sands and shales may |)rev('nt the escape of oil and gas where these beds outcrop a short distance south of the w<']ls. 2. The dip of the fault plane may Ix' a low angle, and the oil may he derived frojn an accumulation in the fault zone and a gradual ti-ans- mission into the overlying beds of Tejcn formation. Several factors may be mentioned in support of this theory : '{a) At a depth of about 1700 feet in the new well of the Great Republic Oil and Paint Company (weW No. 2), the drill passed through Tejon shales and entered a stratum of very heavy oil or asplialtum. The i)roductive oil above is of medium gravity. ib) One mile west of the Great Republic property, a well drilled by the Hill Top Oil Company started at the surface in the Tejon formation, and at a depth of 1000 feet entered red rock and softer formations, which ap])areutly belong to the Sespe age and nornudly lie above the Tejon l)eds. This well attempted to produce very heavy oil from the so-called Hespe beds. The presence of asplialtum in the first mentioned well, and Sespe beds in the latter well, would indicate a northward dip of the fault plane between the Sespe and Tejon formation at this point. Under such conditions it is possible that oil has accumulated in the zone of faulting and has permeated fractured shale of Tejon age directly above the fault contact. At any rate, the presence of oil in the Tejon forma- tion, under such conditions, opens up possibilities in an extensive belt of Tejon running east and west and bordering the fault which is the l)rincipal feature of structure on the north side of this field. This region certainly warrants detailed study of underground and surface structure. In only one other field in the district — the Simi field — is the Tejon formation know^n to be productive, and production in this case is obtained from the upper portion of this formation, as contrasted with the middle or lower Tejon which is productive in the Ojai field. Due to the hard character of the Tejon strata, in contrast to the younger beds of Sespe and Vaqueros, which contain the main produc- tive horizons in the county, it is not to be expected that the production from the older beds w'ould be as rapid. It has been proven, however, that Avells drilled into this formation produce oil on a commercial scale THIRD ANKIAL REPORT. 331 for a much longer i)eriod than wells producing from the softer forma- tions, and it is therefore possible that an investment in drilling in this area would prove profitable. Numerous attempts have been nvade to obtain production in the region of Sulphnr ^lonntain, the .southern and western limits of the field. Up to the present time ;dl efforts to obtain conuiiercial pi-oduc- tion have met with failure. The ju-esence of numerous large siH'pages will undoubtedly attract new opei-ators to this region, especially since the advent of new oil fields recentl\- developed at the western end of Sulphur. Mountain, near the Ventura River. The possibilities of this region can not now he estimated. Production and Water Conditions. Production for the field, as reported for the fiscal yeai", amounts to 64,971 bbl. of oil and 148,892 bbl. of water. This is a daily average of 210.4 bbl. of oil and 408.1 bbl. of water for the field, or (i.4 per cent of oil and 12.4 bbl. of water per producing well per day, the proportion of water being 62 per cent. The production of oil reported exceeds production for the previous year by approximately 50 bbl. per day for the field. Several wells of one of the larger companies are rei)orted to be making from 90 to 95 per cent water. The condition of these wells should be investigated immediately, the source of the water located, and the water excluded before further damage occurs to the oil measures. TABLE IX. Ojai Field.

Developments of great iiM|>()ilaiiee have taken place diiriiii: the past yeai- in this field, and uiHloubledJy greater interest lias l)een aroused ill tile |)rospec1s of tilis lield than ill any other field in the eoiinty. 832 STATE OIL AND GAS SUPERVISOR. Two important additions have been made to the proved area of this field, and there are prospects for considerable increase in production for the county. Production has been obtained from two areas in the field. The first mentioned area is known as the Ventura field proper; llie laftci- area lies in the western extension of Sulphur Mountain, where tliis ran^e is cut by the Ventura River. SOUTHERN PORTION OF THE FJELD. In that portion of the field located on the Ventura anticline, only one M-ell was started during the past year. Six other wells, ^however, ^\hich were reported as having commenced drilling in the year previous, are still uncompleted, and are therefore to be considered as new wells, ('perating companies in this district include the Shell Company of California, with four drilling wells, the State Consolidated Oil Ccm- pany. with three drilling wells and one completed well, and the Ceneral Petroleum Corporation, with two wells drilling and one well completed. Geology. All the wells drilling in this area are apparently located close to the axis of the Ventura anticline, which crosses the Ventura River about two and a half miles north of the city of Ventura. Drilling starts in beds of Fernando age, and the deepest well so far drilled (4000') has probably not yet penetrated the entire series. It may be possible, how- ever, that the lowest formations penetrated should be classified with the Puente formation instead of the Fernando. Definite evidence as to the exact age of such formation is lacking. One company estimates the original thickness of Fernando beds in this region as being approxi- mately 80Q0'. The anticline upon which these Avells are located can be traced on the surface for a distance of about twelve miles, the easterly end plunging under the Santa Clara River Valley, north of Saticoy, and Ihe westerly end disappearing in the Pacific Ocean close to Pitas Point. The fold is mantled by the Fernando formation throughout its entire extent, typical species of the fauna of this formation being found at numerous places. The structure of the anticline, where it is cut by the Ventura River, is revealed as a simple fold, striking almost at right angles to the river, dipping uniformly on the north and south flanks at an angle of about 45° and plunging slightly towards the west. Tlie fermations penetrated by the drill are essentially soft sands, line and brown shales, and sandy shales. Large quantities of salt Avater, usually accompanied by an inflanunable gas, are encountered in drilling. The water usually flows from wells in the Ventura River Val- ley after drilling below a depth of about 1000'. In only one well in THIRD ANNlAIi REPORT. 333 this area has the salt vvatiT failed lo How from llic well. This is prob- ably due to differences in elevation of a|)i)roxiniately 350', whicli is roughly equivalent to an added pressure of about 150 pounds per square inch. Character of Oil Formations. According to populai- opinion, two oil zones have been encountered in this area to date. An upper zone, which produces oil of 56° Baume gravity, is separated by several hundred feet from a lower oil of 30°. It seems more likely that the two so-called zones are not separate and tlistinct, l)ut that the gravity of the oil becomes progressively lighter from the lower or heavier oil sands to the upper or lighter oil-bearing formations. As a proof of this latter assumption may be cited a well which was drilled and finished to a depth corresponding approximately to one-third of the distance between the two so-called zones, this well liaving produced a (juantity of 48° gravity oil, the uppermost oil sands having been cemented off behind the 8]" ca-ing. Every well drilled in this field to date, except one, has failed io nuUce a definite water shut-off above the first showing of light oil. This fact has led the operators until recently into the belief that the light oil sands carrietl water. It was only by the accidental freezing of a string of ca-ing. which was being carried with heavy mnd-fluid in a well, that water was shut off', temporarily at least. Subsequently an oil sand was encountered a short distance below this shut-off. which produced clean oil of very light gravity. The fact that this upper oil sand produces clean oil definitely disproves the theory advanced by several of the operators that this zone carried water. The stand taken by this department in the past has been that the top oil zone should be considered free from water until proved otherwise. Recent Developments. In the proved area of this field five wells are drilling, two wells are idle, and one well is completed. The completed well was drilled by the ■>■} rc|)<)i't('tl as being ciicduiilci-cd in lln' upper oil lidri/uns, and Ihe enni- pany lia.s proposed to (lee|>en llie well in an attempt to jn-oduee IfoiM Ihe lower and heavier jjiravity oil foniiations. Water has never been exeluded from this well, in spite of the fact that it does not tlow. and there is a possibility that formations carrying light oil have been penetrated and their oil contents not reeognized. The Shell Company of California, in their well No. 1 "MJosnell," ca-ed off all upper oil-bearing formations carrying light oil, failed to shut off water, and have been endeavoring to produce from formations lower in the oil seri&s, which carry oil of about 30° gravity. The ytrospects of this portion of the zone can only be estimated at the I. resent time, but from all indications this zone may become very productive. This well is being drilled as a prospect well, and it i.s the intention of the company, after having prospected the deeper oil measures, or in calug the loAver portion cf the well and shut off water at the proper depth. Oil and water are now flowing from the well under consider- .•)ble pre-isure. and the fact that oil would tiow at all. with a water •olumn ( f approximately 3200'. exerting a pressure anywhere from 700 to 1400 lb. per square inch at the bottom of the hole, is sufficient evidence to warrant the assumption that there is a considerable quantity of oil in the pool under pressure great enough to make it flow. Shell Company well No. 1 "Hartman" (Sec. 22. T. 3 N.. R. 23 W.. S.B.B. &j\I.) was completed into the upper oil horizon and the well put en pump. After landing a perforated oil string at this stage, the well made practically no fluid. Upon bailing inside the 8^" oil string, it was discovered that only about ten barrels of oil would come in. but the well would flow oil and water between the 10" water strine: and the 8|". For a time the well was kept bailed clown to alwut 1!)00'. and from eight to ten ban-els of oil and about eighty barrels ( f water would flow from between the ca-ings. The 8|" easing was linally pulled out and found to be collapsed. The well was then cleaned out and pumped inside the 10" casing, obtaining about 2'^ bbl. of oil and 3fM) bbl. of water per day. Subsequently the well sanded up. was cleaned out. the liotfom of the hole redrilled. and 6j" perforated landed en bottom. Pumping inside the 6]" i)roducecT only water at the rate of 300 to 400 bbl. \)or day. By keei)in':r the well pumped down, however, at the above rate of watei- production, oil would flow lefwecn the <){" and 10" casings at the rate of 20 to 40 bbl. per day and no water. Tpon the ermpletion of the ad.joining Oeneral Petroleum Corpora- tion well Xo. 1 "Barnard." production at this well dropped off to about five ban-els oil per day. Iiedrilling was started ti> shut off water :;:'»(» .STATIO OIL AND (iAS SHI'KKVISOK. sonu'what above the former depth, for the purpose of testing an oil showing which had been previously passed aiid cemented l)ehind the 10" easing. The attempt to exclude water proved a failure. The evidence at hand shows the conditions at this well to be rather unique. The source of the oil flowing between the casings was undoubtedly somewhat above the bottom of the hole, since no oil would enter the well through the perforated pipe. It is po.ssible that the water pres- (sure was lowered sufficiently to allow oil to enter the well when the well was pumped. In this ease it would seem more natural for the oil to rise than to seek lower levels and enter the perforated pipe. Just how far up the hole the oil was entering is not known, but it seem'j probable that the source was from an oil sand logged about 40' above the shoe of the 10" water string, and that both oil and water v>ere flowing around the shoe of this casing. Well No. 1 "Taylor," of the Shell Company, located in Rancho San Miguelito, encountered a large volume of gas in formations which correlate with the first oil horizon. The company attempted to pro- duce- this gas without success, probably due to the fact that water was not ."-hut off, and that the perforated pipe sanded up. After landing a string of 6|" with perforated pipe on the bottom, an attempt to produce the gas was made by bailing and swabbing the well. Very little gas was in evidence. Upon ripping the 6^" casing, however, to redrill the well, the original volume of gas was again in evidence, and it was some time before the pressure was overcome sufficiently to allow the mudding of the well. The company then redrilled this.well and attempted to shut off water several hundred feet above the gas forma- tion-, to test out numerous formations which were originally logged iis showing oil, but Avhich had been cased off. Water Avas shut off temporarily, breaking in again after drilling 4' ahead of the casing. ITaving failed to shut off water, the company abandoned the idea of l)rnspecting the upper oil formations and proposed to again pa.ss them lip and drill for deeper oil showings. Summary of Recent Operations. In reviewing operations in this field during the fiscal year, it should be borne in mind that the drilling conditions encountered are unusual Jind exti-emely difficult to overcome. Due to the soft character of the Fernando formation, and the pre-sence of large volumes of salt water and gas, prospecting is very hazardous and oil .shoA^ings hard to iden- tify. The aj)parent lack of suitable shale bodies in which to cement or land the water string, tends to complicate the situation. Further- more, the ability of cement to set and permanently excliide water, in the i^resence of the gas and salt water, which may be constantly in mot ion. is seriously (|uestioned. Innumerable attempts to cement wells THIRD ANNUAL KEPORT. 337 in this area, and exclude walei- permauontly, liave in every ease met Avitli I'ailnre. The writer has constantly urged the use of thick mud-laden fluid, Avith a tapering shoe driven in tight hole in shale, as an experiment to replace the cement method, but until very recently this idea has not found favor. The accidental shutting off of water, due to the freezing of a string of casing which was being carried in a column of thick mud, which case was mentioned previously in this report, has finally turned attention to this matter, and several companies are now propos- ing to try the experiment, using mud only, instead of mud and cement. Another factor which seemingly has been a canse for failure to shut off water, is th€ tendency of the various companies to carry the water string down to and immediately above the first oil horizon, without fii-st having ascertained that water-bearing formations would be encountered in such close proximity to the oil formations and possibly having pene- trated excellent shale bodies at shallower depths in which a water string could be landed with better results. In perhaps one-half of the cases of failure to shut ot¥, the cause may be directly attributed to the fact that the water string was carried down through a portion of the upper oil measures, thus adding three undesirable factors — gas, oil, and water — the latter a flowing water under normal conditions. To these drawbacks must also be added the necessity of keeping the v.ell thoroughly mudded preliminary to cementing, in order to mini- mize the heavy pressure, and the subsequent impossibility of thoroughly Avashing the hole ahead of the cement. Under such conditions it is not surprising that so many failures have occurred. Wildcat Wells. The following wildcat wells arc being drilled outside the limits of proved area in this field : Shell Company of California '^McConigle" Xo. 1, Sec. 23, T. 3 X., R. 23 W., S.B.B.&M. General Petroleum Corporation "Hob.son'' Xo. ], Sec. 22, T. 3 X., R. 24 w.. s.B.B. & :\r. "McGonigle" well Xo. 1, of the Shell company, is drilling one and a quarter miles in an air line east of the productive area of this field. It is located on the eastern extension of the Ventura anticline. After reaching a depth of 2000' the well was bridged and a water string cemented at a depth of about 2800'. Upon cleaning out, the well flowed several million cubic feet of odorless, inflammable gas, and about 300 bbl. of water per day. It has reached a depth of about 3100' and no oil showings have been reported. General Petroleum Corporation wells X'os. 1 and 2 "Ilobson" are drilling on the extreme western end of the Ventura anticline near the 22—41804 338 STATE OIL AND GAS SUPERVISOR. Pacific Ocean, and are apparently testing this portion of the anticline. As in the producing area, drilling is very difficult on account of salt water and soft sandy formations. "Well No. 1 has reached a depth of about 2600', at which depth the 6^" casing was frozen and sidetracking was begun, using a mud circulator. Water has not yet been shut otf in this well and no oil bearing formations reported as having been encountered. Well No. 2 has been drilled to a depth of about 1270', and has been idle for the major part of the year. Water has not been shut off in this well. Conclusions. The results of drilling in the southern portion of the Ventura field, during the fiscal year, indicate that farther and more extensive developments will be carried on during the coming year. Although the possibilities of the field, from a productive standpoint, have not yet been realized, due to the difficulties in handling the water situation, wells already producing from the light oil horizon have proved to the satis- faction of several operators that this zone is worthy of development alone. In addition, the opening up of deeper oil formations carrying heavier oil as in the Shell Company "Gosnell" well No. 1, the oil being accompanied by a good gas pressure, has given the field a prominent place in prospective productive value. It is confidently expected that the solution of the water problem Avill shortly be found, and that soon thereafter the completion of the wells will be assured. With the finishing of the present drilling welLs, and the knowledge thereby gained as to the underground structure, will come an extensive drilling campaign, which will probably affect a wide area near the anticline east and west of the Ventura River. NORTHERN PORTION OP VENTURA FIELD. During the past year a new company, called the New ]\Iexieo Oil Company, has succeeded in proving up new territory which is just east of the Ventura River and several miles west of Sulphur Mountain. The new wells are located in Rancho Ex i\Iis.sion de San Buena Ventura, and would fall in Sec. 33, T. 4 N., R. 23 W., S.B.B. & M.. if subdivided into sections. This company is not the first company which has drilled in this vicinity. Starting in seepages of oil which occur about half a mile northwest of the group of wells now producing on the property of the New Mexico Oil Company, four wells have been drilled in what is known as Jennings Canon. The first well is reported to have been drilled by the Philadelphia California Petroleum Company in the very early days of oil development in California, probably between 1865 and 1870. Neither maps nor records give a clue to the history of this well. The iron casing is still visible at the surface, and heavy oil oozes out. THIRD ANNUAL KKT'Oiri'. 3:W Til tlic year 1900 two wells were drilled by the San IJueiia V^entura Oil C'oiiipany No. 2, being only a shoi't distauee from the well drilltMl by the Philadelphia California Petroleum Company 300' south of the Dixie National rig now standing. No. 1 was located on the property of .1. Ilollingsworth. near what would be the southeast corner of See. 32. T. 4 N.. R. 23 W., S.B.B. &M.. if subdivided. No. 1 was drilled to a depth of 1300'. and no oil being found, was abandoned. No. 2, which was started in an oil seepage, was drilled to a depth of 300', only traces of oil being encountered. It was unproductive, and therefore abandoned. In inOl or 1902 the Constitutional Oil Company drilled one well in the group around the Philadelphia California Petroleum C'ompany well in Jennings Canon. 11 was located 300' north of the San Buena Ven- tura well No. 2. After drilling to a deptli of 400'. a production of only about four barrels of oil per day was obtained, and the well w'as therefore abandoned. The last well to be drilled in this group was drilled by the Dixie National Oil Company in 1908. It was located 11^ feet south of the well drilled l)y the Constitutional Oil Company. It was drilled to a depth of 720 feet, encountering oil between depths of 300' and 350'. The production amounted to only three to four barrels of 16° gravity oil per day. and all casing was therefore pulled out, no plugging having been done to protect the oil from a larger quantity of water also eiicount(M'e(l. The rig over this well is still standing. New Mexico Oil Company. The amount of work done by this company during the pa.st year is shown by the drilling of seven shallow wells near the center of the property. The productive formations from which this company derives its oil have never liefore been tested, and with the exception of the small producing wells mentioned above, no production has been obtained from this part of the county. The work of drilling commenced on January 10, 1918. Brown sliale was encountered to a depth of 48'. at which depth oil of 29° Baume entered the well and stood within 15' of the surface. Another hole was then spudded in, only four feet distant, in w^hieh oil was encountered at the same dej^th. The original hole was then deepened to 220'. and oil reported at dej^ths of 128' and 175'. Subsef|uently six other wells were drilled and formations encountered similar to the formations penetrated by well No. 1. All production so far has been obtained fnmi seams in brown shale. Very little water is encountered above a depth of CAW. At this depth, however, considerable water is found in several wells, and it has become necessary to plug llie lower ])()rtiou of a number of tlie wells. 340 STATE OIL AND GAS SUPERVISOR. Geology. A study of the .surface geology near the wells of the New jNIexieo Oil Company show.s that the wells are located a short distance south of the axis of an anticline which is here developed in the Monterey formation. This anticline is very nearly parallel to the fault which marks the con- tact between the Fernando and the Monterey formations, and which can be plainly seen about one-half mile to the south. The direction of the anticline at this point is N. 50° E., and the dip on the north and south flanks ap])roximately 50° close to the axis. The north flank of the anticline soon develops into a syiiclinc, so that the exact location of the two structures may be easily confused unless care i.s taken in mapping. The anticline has been followed some distance west and one mile east from the camp of the New Mexico Oil Company, Toward the east it swings to the south, roughly parallel to the major fault men- tioned above. The oil is obtained from shale which has not been eroded at the surface. This probably accounts for the high gravity of the oil. Due to the fractures in the shale, some oil has reached the surface from the shallow oil horizon, and numerous seepages occur at this point and further east close to the axis of the anticline. Further to the south are exposed oil sands, which at one time covered the anticline. Large seepages are found at several localities, the oil originating from the.se exposed oil sands. There is a possibility, therefore, that commercial production of a heavier oil may be obtained on this property between the region of present development and the fault which marks the southerly limit of the Monterey. Future Developments. At the present time two new wells are drilling .some distance north and east of the New Mexico Oil Company's property, one by H. L. Hayes and the other by the Riva Oil and Gas Company. The Ha3'es well is located practical^ on tlie axis of the New Mexico anticline, and about half a mile east of the latter company's well. It would seem that the prospects for obtaining oil in this locality are as favorable as on the New Mexico lease, since .structural conditions and the oil formations are very nearly the same. The wildcat well being drilled b}^ the Riva Oil and Gas Companj^ is located near the south line of Sec. 27, T. 4 N., R. 23 W., S. B. B. & M., and about one mile northea.st of the Hayes well. An examination of the geology of this vicinity shows that the well is located on the north flank of the syncline which parallels the New Mexico anticline on the THIRD ANNUAL REPORT. 341 north. It is, therefore, al)oiit half a mile north of the New Mexico anticline, and any production obtained at this point will no doubt open up much larger areas in this field for development. Production and Water Conditions for the Entire Field. The production of this field for the fiscal year amounted to 17,848 bbl. of oil and 104,228 bbl. of water, or a daily production of 161.8 bbl. of oil and 527.6 bbl. of water for the field. Tiie production per producing well per day was 18 bbl. of oil and 58.6 bbl. of water, or 76.7 per cent water. Of the 17,848 1)1)1. of oil i>roduced by the field during the year, approximately one-half was produced from tlie New Mexico anticline in a period of three months. The water produced in this portion of the field amounted to only 1 per cent, so that the coi-rect percentage of water for the Ventura field proper is 91 per cent. This will serve as an idea of the water situation on the properties of the Shell Company of California, the State Consolidated Oil Company, and the General Petroleum Corporation, which companies are the only operators in the Ventura field proper. As previously mentioned in this report, it is hoped that, during the coming year, the water troubles will be over- come by new methods and the amount of oil production greatly increased. TABLE X.

The penetration of foi-mations described as "Metamorphic" led to a discontinnance of drilling and the conversion of the wells into water wells. No oil is reported as having been encountered. The well being drilled by Jose])h 1). Dabney is located on the axis of a plunging anticline approximately one and a half miles north of the town of Camarillo. Drilling starts in beds of upper Fernando or San Pedro formations. The dip on either flank of the anticline is approximately 30° and the axis at this point is noticeably plunging toward the west. At the present writing the drill has apparently passed out of the Fernando formation and entered beds of probable Puente age. A slight showing of oil was noticed near the contact of the two formations. As the beds which underlie the Puente formation are exposed further up the anticline and in South Mountain to the north, it is probable that a continuance of drilling will expose the Vaqueros formation, which is here interbedded with conglomerate and some basalt, and possibly the upper portion of the Sespe formation. There is undoubtedly a marked unconformity between the Fernando and Puente beds, since the Puente is entirely missing where the Vaqueros is exposed on the rising end of the dome about three miles east of the well. The True Oil Company is still engaged in the deepening of its well in the Cuyama Valley in Sec. 2, T. 9 N.. R. 24 W., S. B. B. & M., near the northwest corner of the county and about 22 miles south of Mari- copa. Bulletin No. G21-M issued by the United States Geological Survey on ''The Geology and Oil Prospects of Cuyama Valley, Cali- fornia.*' describes the conditions at this well, which was originally -started and drilled to a depth of 1800 feet by the AVebfoot Oil Com- pany, as follows : "The Webfoot well, in a nan-ow gulch on the north side of Ballinger Canon, in the S. W. quarter, section 2. Township 9 N., Range 2-4 W.. was started about 1905. and drilling continued inter- mittently for a unniber of years. It is said to have reached a depth of 18C0 feet without encountering any oil. The well starts in nearly vertical t)eds of In-own sandy shale of the ^Monterey group." The conditions, as rei)orted in this article, have been veritied by the writer and found to be practically as stated. Drilling during the past vear has not disclosed oil in connnercial quantities.

During the fiscal year 1917-1918 this department received 36 notices to drill new wells in the Casmalia field. During the same period 47 new wells were added to the list of producers, and only five wells were abandoned. All of the wells which were abandoned were located on the outskirts of the field, and in "wildcat" areas. The several tables accompanying this report show the amounts of oil and water produced. There are several factors wliich render the drilling of wells, and remedial woi-k for colli rol of the water in this field, uncertain. They are: (1) The porous character of the hard oil-l)earing brown shales; (2) Absence of sand strata and difficulty of correlating blue, gray and brown shales; (3) Difficulty of defining the location of the hot bottom water. 362 STATE OIL AND GAS SUPERVISOR. (4) Tlie possible admittance of top water to the oil-bearing brown shales. (5) The uncertainty of position and of the correlation of top waters. These several factors are discussed as follows : (1) The hard brown shales are metamorphosed marine sediments, essentially chalcedony or flint in composition. They are usually com- posed of alternating laj^ers of hard and soft shale, and the whole mass seems to be creviced and fractured. They constitute a very hard, yet porous, medium. The porosity is always considerable, but is found to be quite variable in different locations. Examples of this are given elsewhere in this report. It is Imown that oil, water, mud and cement have found easy passage through them. The lateral ti-avel of botli top and bottom water through these In'own sliales has complicated the i)rol>lem of securing proper protection to llie oil deposits by remedial work. (2) It is quite certain that the contour of the contact of the l)ro\vn and blue (or gray) shales does not accurately delineate the stratigraphy. However, a study of a peg model has led to the conclusion that such correlation is a rational basis for making a further study of conditions. The accompanying contour map shows the top of the hard brown shale, the upper portion of which in the western part of the field is known as the tar zone. In several wells the positions of the top of the hard brown shale, or its equivalent, are hard to determine. This is probably due, to some ex- tent, to the different formational names applied by tlie various drillers. The underground structure of the field, as shown by the contour map. Fig. 1.3. which is based on the logs of wells, corresponds in a general way to that accorded to it by a study of the surface conditions alone. The main anticlinal axis has a northwesterly-southea.sterly trend, but this appears to be sui)plemented by smaller anticlinal spurs, and by domes. The existence of at least one sharp fold is shown, along which it is possible that faulting has occurred. The theory has been tentatively advanced that block faulting is probably responsible in part for the irregularity of the contact of the shale members. Aside from the fore- going, it is probable that the hardening of the brown shale has taken place along zones that are not entirely parallel with the bedding planes, and that the reservoirs of oil and gas are defined by the lines of least resistance within these zones. Hence the porosity, and not necessarily the stratigraphy, has determined the migration of oil and gas. Wher- ever brown shales are found in this area, such coloration is due to petroliferous saturation, and it is probable that the porous portions of bodies of shale, once blue or gray, in contact with this zone, have been similarly colored. THIRD ANNUAL REPORT. 363 (3) The hoi holtoin water is carried by hard brown shales, which an^ identical in character to those carrying tlie oil. With the exception of one well, any parting ])etween the two flnids has never been definitely located. When drilling in the oil nieasnres, water must be used to hold back, or "lubricate." the heavy oil, in order to allow the tools and bailer to work properly. Although a well may be drilled too deep, the pres- ence of this bottom water is not evident, usually, until the well has pj'oduced continuously for several weeks or longer. The following is the ap])arent reason for this condition: As the head of viscous oil is removed from a well that has been drilled too deep, and as the gas pressure diminishes, the less viscous water finds easy access to tlie pump, and the oil is thereby held in cheek from enter- ing the well. This bottom water has been known to flow from the top of a well, but only after the well had produced oil for some time. For the elimination of bottom water in these wells, successful plugging operations are often diflficult. The heavy oil works into the cement, and thickly coats the walls of the hole. The .setting of the cement and its bond with the walls of the hole are therefore rendered uncertain. (4) In the western portion of the field, the policy of cementing two water strings has been followed. The upper string was cemented for the purpose of excluding the top water from the tar zone. The lower string was cemented for the purpose of separating the cool, heavy oil of the tar zone from the hot, heavy oil of the oil zone, and as an additional protection to the oil zone, in case the top shut-off became ineffective, or in case the top water was let into the tar zone by some other well. In the eastern portion of the field, conditions are somewhat different, inasmuch as the present productive measures appear to correlate Avith the above-mentioned tar zone. Therefore one water string has been the rule in that area. In the west side of the field, several water strings have been carried as low as 400 feet into the tar zone without taking any precaution, with the exception of an inadequate amount of cement, to hold the top water above the porous brown shales of the tar zone. It is true that the most conspicuous cases of this condition are shown in the first wells drilled in this area. During the drilling of these wells practically noth- ing was known of the underground conditions. After water has been let into the tar zone, it can no doubt travel through the porous shales to other wells, and, if the second shut-off is not effective at a well, it will pass down tlie hole, or around tlie outside of the cement, and enter the oil zone below. It is known that cementing done in these shales, without the application of mud fiuid, is liable to be a failure, on account of the cement running out laterally into the formations. In several wells water has been logged in the tar zone. However, it has not been con- clusively proved by pumping test that primary water exists there. 864 STATE OIL AND GAS SUPERVISOR. (5) In drilling some of the finst wells in the Casmalia field unexpected water was found below the top shut-offs. This demonstrated that the position and number of these top watei-s is erratic. It is probably- responsible, in a measure, for some of the first wells having their second shut-offs too deep, the object being to make certain of getting below all top water. The result of this overreaching is discussed under No. 4. The formations being generally favorable, the operators have adopted the plan of drilling the wells, down to the first considerable shows of oil, with as little drilling water as possible. Thus in most cases they are drilled "dry," using just enough water to properly mix the drillings. By this means the location of top water is easily determinable, except when a strong flow from one water-bearing formation is sufficient to fill the hole enough to void the possible evidence of a lower water. Some wells of late have been drilled to the productive zone and thoroughly tested before final shut-off point was decided. In other cases shallow shut-ofts have been made, for prospecting purposes, either by cementing or by formation shut-off, below all probable top water. Then the wells have been drilled dry to the productive zone, after which the lower shut-offs have been effected on top of bridges. In the eastern portion of the field, one water string has been the rule, but in some cases, as described above, the operator has considered it good policy to make two shut-offs. The following is an illustration of this idea : In a new well, drilled in this way, a temporary formation shut-oft' was made at 396' wuth 12^" casiiag, to exclude all probable top water. On the notice for drilling this Avell it was proposed, and this department approved the plan, to mud the formations between the 12^' and the 10" slioes, to cement the 10" ca.sing, and to then remove the 12^" casing. A 20" hole was drilled and about 220 cu. ft. of mud was converted into mud-fluid and placed l)ehind the 12^" casing at the sur- face. The mud-fluid did not fill up to the surface. Water logged at .310' was reported to have entered the hole at the rate of 50 bbl. per hour, and to have risen to a level of 240'. The 12^' casing successfully excluded the top water, and the well was then drilled di-y to a depth of 850'. The deputy was called, and it was witnessed by bailing test that the formation between 396' and 850' carried no appreciable water. Drilling was continued under the same conditions to 1595', when it was again witnessed by the deputy that the formations encountered below 396' were dry. The casing was moved to more adequately demonstrate this point. Later the superintendent reported that the well had been drilled to a dcptli of 1873' into brown shale, with no water showing The formations ])elow 396' were then nmdded, using alxmt 50 cu. yds. of mud fluid, and the 10" casing was cemented in gray shale at 1845', using 150 sacks of hydraulic lime, followed by 200 sacks of cement. THIRD ANNUAL REPORT. 365 When tested, the 10" shut-off was approved by this department. In- stead of pulling 12^" easing: as contemplated, the superintendent decided that it was good insurance to leave the casing undisturbed. In addition to the advantage mentioned under No. 5, of drilling the wells dry, there is a distinct increase in rate of drilling over results obtained by "drilling wet." One Casmalia operator believes that the average total time of drilling his wells "dry"' is only about one-half of the time consumed by the "wet" method. Another superintendent give.-; his idea of the average results as follows: Where a 1000' well cDuld be drilled "wet" in 40 days, tlie "dry" meth(»d would reduce the lime to :M) days, effecting a time saving of 2.') per cent. In so far as the mere capacity of the l)it to jienetrate the formations is concerned, results indiciite that "drilling dry" can accomi)lish, under ideal conditions, as much as eight times the amount of hole possible by the "wet" process. Some of the factors which tend to minimize the value of "dry" drilling are: (1) Caving formation, which usually necessitates carrying casing near the drill, and underreaming for same. In the "wet" method, the hole is usually drilled for several hundred feet, in this way, with open hole, using a proper size bit to obviate the necessity for underreaming ; (2) Permanent or temporary shut-offs that might otherwise be omitted. The haphazard occurrence of the different top waters some- times makes it more economical to finish the hole at least partially "wet," in order to avoid the expense of handling casing for any other shnt-off's; (3) Heavy oil entering the hole, and necessitating the use of water to hold it back, and to "lubricate" it for a sufficiently free action of the tools. p]specially is this true on the west side of the field, where the oil is as heavy as 8° Baume gravity. - On account of the above-mentioned conditions, each well is really an individual problem for the determination of the best procedure to accom- plish the drilling (?. c, "wet" or "dry"). During the past fiscal year the operators of the Casmalia field were urged by the Mining Bureau to experiment with mud-laden fluid in the drilling of wells with standard tools. The porous, fractured brown shales of this area are known to constitute a medium which permits of a considerable migration of fluid whenever opportunity oft'ers. The idea was to fill the cavities with mud fluid, and thereby build up an impervious jacket around each well. With this accomplished, the result was figured to be the .sealing of the strata, and the confinenuMit of any oil and water bodies to their original positions, and also to have the effect of keeping the cement from traveling laterally into the shale during the operation of cementing a water string. ^nf) STATE OIL AND GAS SUPERVISOR. Tlic production of the Casmalia fic4d is obtained by three companies, the Associated Oil Co., Doheny-Paeific Petroleum Co., and the Union Oil Co. About the first of 1918 two of these companies began using inud-rtuid in an efl'ort to avoid serious water conditions. It is yet too early to gauge the results of these operations by production reports. At about twenty wells drilled with cable tools mud has been used in varying amounts and under varying conditions. The shales adjacent to the wells have taken from 10 to 240 cu. yds. of mud-laden fluid per well, indicating a great variation in porosity. In some cases the mud was put in under an extra pump pressure of several hundred pounds per square inch, while in others the mud was simply circulated, and more mud was added around the outside of the pipe at the surface, as the mud receded. It is reported that mud was thus added as many as five times, in an effort to maintain its level at the surface, but that the desired result was not obtained. The scarcity of good mud in the vicin- ity added to the difficulty of the operation. The best quality obtained was taken from old sump holes. One operating company carrying out the mudding operations per- sistently was not satisfied until a permanent column of mud reached the surface, but in other cases the work was not properly done, and best results could not be expected. In a few cases mud has been placed behind both water strings. In these cases, in the western part of the field, the tar zone was mudded at the final operation. As an illustration of the beneficial results from the use of mud at Casmalia, an outline of operations of well No. 14, Soladino, of the Doheny-Paeific Petroleum Company, is given as follows : A string of 12^" casing was cemented in blue shale at 1025' and a string of 10^' casing was cemented at 1120', the shoe of the latter string being at the contact of blue shale above, and brown shale below. There had been only a small amount of water found below the shoe of the 12^" casing, and this water was apparently not active enough to show the condition of the 10" shut-oft' in its true light. This shut-off seemed to be success- ful. There had been used 100 sacks of cement, but returns of water did not reach the surface. It was noted that the water back of the casing came within 30' of the top. The well was drilled in and started producing, after which considerable water appeared. Bridging and testing proved that the water had broken in around the 10" shoe. A strain was put on this pipe, and it was easily removed from the well. When the casing was examined, it was found that only about four feet of cement showed above the shoe. The cement had evidently traveled laterally and downward into the porous brown shale. Being unable to loosen the 12^" easing, the formations below the 12|" shoe were thoroughly mudded under pressure, using 170 cu. yds. of mud-laden THIRD ANNUAL REPORT. 367 fl'.iitl. The 10" was then cemented at 1168'. When pnmpino- in the cement, mud-fluid was displaced and overflowed at the surface, indi- catinof that the cement went up back of the pipe. TJpon testing, the .sliut-off was approved. The following cases illu.slrMte the variation of tlie jioi-osity of tliese brown shales: (1) Muilding opei-ations were about to be started on a well, but, due to the fact that the formations would take but very little water under a pump pressure of 300 lbs., the mud was not used. (2) A new well was started with rotary outfit. It was found imprac- ticable to maintain circulation, although a large quantity of chopped rcpe and other material calculated to retain the mud was introduced. At a depth of about 400' standard tools were substituted. The average condition of porosity of the hard brown shale, as noted by drilling operations, leans toward case No. 2, rather than toward case No. 1.

The use of water analyses to indicate the source of oil well waters, lias afforded considerable valuable evidence in connection with the Cali- foi'iiiaii fields. The accompanying table of "Chemical analyses, (fig. 14), of oil-well water of Casmalia field'' shows conclusively that they are also of economic value. The most reliable distinguishing chemical characteristics of the average samples of the "top" and "bottom" waters are as follows: (1) "Secondary alkalinity," which .shows the amount of carbonate of calcium and magnesium to be greater in the top waters; (2) "Total dissolved solids," which is greater in the bottom water. This condition is usually true and is explainable by the fact that the deeper water has traveled a greater distance through formations, and therefore has had more opportunity to dis- solve mineral matter therefrom. This idea assumes that the top water is of meteoric oritjin. (3) "Per cent of rS04 in rS04+rCl. which is greater for the top water. The presence of more sulphates and less chlo- rides in top water is a common phenomenon in the oilfield waters of ralifornia. 368 STATE OIL AND GAS S^UPERVISOR. ^i to o ■sio- s <^ C? 3 cs <5> § § § cs % § S ^^ ^ a s g Cs ■<»■ g cs % s « § § § 1 Qi ^ 06 ? o >*i ^ !$ i^ ■♦ 2< ^^ S t2 ^ «ci Us 15 «s to s a ^ g i:^ •^ o=t: 1 _ a: O 1- ?

REPORT. 369 The following is an {'Xi)lanati<)n of the terms used in connection with the "special properties" shown in the table: Primary salinity is a result of a combination of the alkalies, such as sodium and potassium, with the strong acids such as hydrochloric and sulphuric. Secondary salinity is the result of a combination of the alkaline earths, such as calcium and magnesium, with tiie strong acids. Primary alkalinity is the result of a coiubiiiation of the alkalies with the weak acids, such as carbonic. Secondary alkalinity is the result of a coinlii.'iation of the alkaline earths with the w-eak acids*. The Shell Company of California have employed water analyses to determine the presence or absence of new water during the drilling of their well in the Newhall tract. Frequent samples were taken at the bottom and near the top of the water column in the hole, and also of the drilling water that was added from the surface. This method demonstrated the presence and approximate location of new water zones, regardless of the fact that the hole was full of water. In one case a marked decrease in sulphates and increase in carbonates indicated the presence of a new body of water. In "wildcat" operations, or in territory where the locations of water sands or zones are erratic, this method is especially worthy of considera- tion. A few analyses costing about a hundred dullai-s may be the means of saving a string of casing, costing several thousand dollars. Thanks are due F. G. Tickell, resident engineer of the Associated Oil Company at Casmalia, who furnished the writer with considerable data used in the table of "Chemical analyses of oil-well water of Cas- malia field." CAT CANYON FIELD. There has been no new development of intei-cst in the Cat Canyon field during the past year. The Pan Ami'i'ican IN'tioh-iiui Investment Corporation, which conducted the principal deveUjpmcnl operations in the year previous, met with adverse water conditions and snudl pro- duction in the developed area on the Teresa Bell tract. Drilling of new wells in that area has been suspended. It is the writer's opinion, however, that the tract has not been prospected to the best advantage. History of early development, by other companies, along the northerly line of the Los Alamos Rancho, bounding this tract, indicates the possi- bility of the existence of productive formations in the anticlinal struc- ture whose axis almost coincides and runs parallel with the northerly line of the Bell tract. *Kor detailed information on tlii.s .subject, see Bulletin No. 653, of the U. S. Geological Survey, and references mentioned therein. 24— 41S94 370 STATE OIL AND GAS SUPERVISOR. In tho Brooks-Stendell area in the Cat Canyon field tlie Brooks Oil Company and the Palmer Union Oil Company each brought in a new well. The peg model of this area indicates that the productive forma- tions lie in an anticlinal spur, plunging northwesterly, off the north flank of the main anticline traversing the Solomon Hills.

No new development has taken place in the Lompoc field. Nearly all of the proved area in this field is operated by the Union Oil Company, excepting one quarter .section lielonging to the Orcutt Oil Co. The Union Oil Company has producing wells extending over a strip of land, 3.6 miles in length, in the northerly end of the Purisima Rancho. The average distance between wells is 1700'. There is still room for a number of producing wells in this area. The field is not being properly protected from water. It is now producing more water than oil. The following table shows an increase of 6792 barrels of water as between June, 1917, and June. 1918, and a decrease of 2468 barrels of oil, with equal numbers of wells producing.

In the Santa Maria field the principal development of interest has taken place in the eastern portion of the field along the east-west line dividing the properties of the I'nion Oil Company and the Western Union Oil Company. In this area six new wells have been brought in with initial productions running as high as 1000 bbl. per day of 26 gravity oil. The production comes from the second oil zone. To date the oil is practically free from water. There has been some variance in the casing programs of the two operators drilling along this line. The question of properly protecting oil bearing formations from water imder the respective programs has been the subject of two conferences THIRD ANNUAL REPORT. 371 between representatives of these companies and this department. The principal question involved is that of the use of cement rather than formation shut-oft's. It is the writer's opinion that cement shut-offs will insure greater durability to casing. The method of drilling in this area, whether by rotary or cable tools, is a matter of minor importance, in so far as shutting off water is involved, as there is a body of nearly a thousand feet of blue shale above the second oil zone in which to land casing. Early in the past fiscal year the Union Oil Company acquired owner- ship of all holdings of Pinal Dome Oil Oomi);iii>- in the Santa Maria District. In the older part of the field, on the Newlove. California Coast, Ilart- nell, Harris and Graciosa leases, the Union Oil Company deepened a number of wells from the second to third oil zone with good effect. On the Harris lease the Union Oil Company drilled well No. 8 to get pro- duction from the third oil zone. This well had not l)een completed at the close of the fi.scal year. Some interesting developments relative to water conditions were noted in this well. These features are given in detail in the Lists of Decisions of Santa Maria field. An intermediate water apparently exists between the second and third oil zones in the area along the Newlove-Graciosa (Harris) line. A number of the earlier wells drilled to the second oil zone in this area may have entered this intermediate water. This is mentioned as an additional clue to those given under discussion of water conditions in the First and Second Annual reports^ with relati( n to the flooding of second oil zone production.

The following is an analysi.s of operations as to drilling, formations, protective work and productions in the Soladino-Arrellanes line wells, Casmalia field, owned respectively by the Doheny-Paeific Petrolenm Company and the Associated Oil Company. The Avells included in the group ni-c: Doheny-Pacific wells: Soladino Nos. 1, 2, 3. 4. 5, G. 7, 8, and 9. Associated wells: Arrellanes Nos. A-91 (old A-2; [P. 0. T. Xo. 1]).

Development. Well No. A-91 was the first well drilled in the group. The drilling was done by the Producers Oil and Transportation Company. The well was not put on production, after being drilled to a depth of 2485 feet, because the oil, logged as asphaltum, was not marketable in 1905. The Casmalia Syndicate took over the Arrellanes property and well A-91 in 1915. A new well. No. A-80, was drilled and the old P. 0. T. well, No. A-91, was redrilled. Well No. A-80 was completed April 12, 1916, at a depth of 1852', and showed an initial production of about 400 bbl. of 8.5 gravity. The well wa.s not pumped for more than a few days at a time because there was no market. The production showed only a small amount of water during these intermittent productive periods. Continuous production at a later date gave radically different results. In October, 1916, the Doheny-Pacific Petroleum Company started drilling Soladino Avells Nos. 1, 2, 3, 4, and 5 along the Soladino- Arrellanes line. These wells, .see index map on cross-section attached hereto, are 300' apart and 150' from the line. Drilling was completed on Soladino well No. 1 on February T, 1917, at a depth of 1865'. The company's records state that from February 17 to February 28, 1917, the well averaged 500 bbl. daily of clean oil. On March 1, 1917, the well produced 1800 bbl. 10.5 gravity oil and on March 2 the production rose to 7000 bbl. and showed some water. On March 3 the production declined to 1600 bbl. fluid and on March 4 the production was 1600 bbl. fluid, showing about equal parts of oil and water. The well was then shut down for one day and the following is a record of the fluid production for INIarch 6 to 31, inclusive : Date Bbl. fluid Per cent water March 6 - .-- --. — . 1,000 l.COO 900 7 8 Little water— no out. 10 11 12 13 H 15 16 (Well shut down to March 26). 27 28 29 (Shut down). 30 (Shut down). 31 9O0 90O 1,000 1,105 1,10) 1,100 1,000 800 850 41 per 40 per .50 per 60 per 60 per 60 per ^ 11 per ) 25 per cent. cent. cent. cent. cent. cent. cent, a.m. test. cent, p.m. test.

THIRD ANNUAL REPORT. 375 It was thought at this time that the water was drilling water, as large quantities had been wasted into the formations in drilling this well. However, the foregoing history of the initial productive period of Soladino well No. 1 is typical, as will be shown later, of that of the following other wells of the group : Soladino wells Nos. 3. 4, 5 and 7, and Arrellanes well No. A-80, and it has since been concluded that the Avater being produced is not drilling water. Drilling Conditions. As a basis for study of the conditions in this group the formations entered by the wells are divided into three zones, namely, Water Zone, 'J'ar Zone and Oil Zone. Thes(> divisions and the respective zone thick- nesses are sliowii on the eross-sce-tion attached hereto. The paramount ditiliculty in tiie identitieation of formations entered l)y the drill in the ('asmalia tield lies in the fact that all formations are shale. Of course the shale is of varying degrees of hardness. I^iere are i)laces in which caves or "rotten shale" occur. AA'hen cer- tain wells were being drilled with hole kept filled with drilling water, large quantities of water ran away into these formations. With the exception of the "Shell" at the top of the Oil Zone, which seems to be fairly persistent in this group, formations stratigraphically equivalent are hard to identify. When the Tar and Oil zones are entered the problem of proper formational designation becomes more complicated as both tar and oil. because of their heavy gravity, follow the drill and contaminate results. Under these conditions, granting the possibility oc separate oil and water strata in the lowest formations thus far entered, the companies have found no practical way in which the drill, or bailing operations during drilling, can register the passing from oil formation to water formation, or the reverse. Lately, as little drilling water as possible has been u-ed in drilling operations. In fact the holes have been drilled practically dry, perhaps using one barrel of water in order to make nnid of the cuttings. This method has been adopted in order to avoid the wasting of large (|uan- tities of drilling water into ])roduetive zones nnd also with the hope of being able to tell tlirough the rise of fluid, if the drill enters a water stratum. decent operations in cementing a string of 121" casing at 020' in well No. A-52^ illnstrnte the difficulties attendant upon operations in tiiase shale bodies.

That is, while drilling with open hole, only enon,'j;h water to mud cuttings w^as dumped in bottom with a bailer. When casing was started into the hole the necessary water was run in from surface. Careful watch was kept of operations. Appar- ently no water stratum was entered in drilling to the depth of 920'. At 920' an attempt was made to cement a string of 12^' casing with ]50 sacks by the Perkins process. The casing was full of water prior to the entry of cement. The water was displaced from the casing and also the cement fluid with very little pump pressure and without fluid returns outside the casing at the surface. On the day following this operation 100 sacks of cement were pumped into the hole outside the 12-J" casing through a string of 620' of 1" pipe. It was stated that returns showed continuously at the surface during this operation. From the fact that there was no water found in drilling this well and that the hole was only 6' ahead of the shoe, when the well was tested for shut-ofi:*, one would naturally expect that, after the hole had been bailed dry and allowed to stand for 12 hours, no water would show in the hole. However, when the bailing test was made, the hole was found to contain 230 gallons of water. Subsecjuent tests showed decrease in the amount of water collecting in the hole, and it was concluded that the water came from shales adjacent to the shoe where it had been forced during cementing operations. It is obvious from the foregoing that conditions in these shales call for something more than the usual cementing operations. Shut-offs. Stratigraphic uniformity in the matter of water shut-offs is a vital necessity in a proper protective program in this group. There was very little definite information available when the first five Soladino wells were drilled other than the casing program adopted, and in later operations consistently adhered to, by the Casmalia Syndicate in well No. A-80. In this well a string of 12^" casing w^as cemented at a depth of 739' above the first "tar show" at the top of the now called Tar Zone, in order to exclude water above this depth. The well was then drilled through the Tar Zone. At a depth of 1420' the drill entered a hard shell and at 1440' entered a hot oil stratum at the toj) of the oil zone. Subsequent drilling has showed the foregoing to be the principal definite segregations. A basic correlation has therefore been made through the shells, logged at the tx)p of the oil zone, in the various wells shown in the attached cross-section.

Progress Chart. The progress cliart. attached hereto, drawn with respect to depths and tune, shows all depth.s, from initial drilling dates to completion, computed and plotted with respect to stratigraphic datum. On this chart, lines of correlation become horizontal lines and the status of any group of operations, as regards stratigraphic uniformity, for any given date, may be studied easily. In order to get the actual deptli below^ surface for any well on any date it is necessary to add the distance from derrick floor to strati- graphic datum. The necessary correction for each well is shown on the chart. Composite Graphic Log. At the left (Mid of the chart is a composite graphic log of the Avells in the group. All water-bearing formations logged in the group are shown. A number of the water strata, logged in various wells, are stratigraphically coincident in the composite log. It is obvious, because of the intimate relationship of the wells, that the knowledge or suspicion of any source of water in any well of the group should be considered in connection with the water problems of all other wells of the group. Original Program for Operations. At a meeting in the Santa ]\Iaria office of this department on the afternoon of March 28, 1917, at which the following representatives of operators in the Casmalia field were present : Mr. W. Can field, As.sociated Oil Company, ]Mr. T. A. Collins, Doheny-Pacific Petroleum Company, Mr. M. A. Kerr. Pinal Dome Oil Company (now U. 0. Co.), Mr. F. Marsh, Casmalia Syndicate (now A. 0. Co.), the following points were discussed relative to operations by the respec- tive companies in the Ca.smalia field: (1) Proper depth to carry top water string. (2) I'roductive value of brown shales, lying between 750 and 14r)0 foot levels, on the Soladino- Arrellanes line. (8) Probable origin of water in the tar zone, whether drilling water, of which the shales consume large quantities, or w^ater stored in crevices in the shales. (4) Should another string of casing be landed and cemented in the slii'll nt 1450' before going into the oil zone proper. 378 STATE OIL AND GAS SUPERVISOR. It was considered to be of primary importance to cement a string of easing in the big shell, mentioned in item 4, or in some formation of a suita])le nature stratigraphically eciuivalent thereto, in order to pro- tect the oil zone. There was believed to be a. variation in the productive quality of the brown shale body, now called the tar /one, mentioned in item 2, and, in order to conserve any production in the tar zone a top-water shut-oft" should be made in suitable formation near the top of the tar zone. In case, however, further drilling of wells demonstrated that there is a considerable area over which the tar zone is not productive, then, it was concluded, a string of casing could be carried to the big shell, mentioned in item 4, and cemented there, using sufficient cement to seal all fornuitions through the tar zone so that there would be no possibility of toj) Mater being carried down below the stratigraphical points of shut oft' in other wells, and tiius increasing the water content of the tar zone. There is little variation from the foregoing in th(i problems that confront the operators at this time. There is the added prol)lem of the appearance of large quantities of water in the production of certain wells, as already illustrated from the initial behavior of Soladino No. 1. The probable source of this water is discussed later. A study of the progress chart for operations after April 1, 1917, will show to what extent the interested parties have followed the under- standing as to proper protective measures developed in the conference of I\Iarch 28, 1917. Tests of Tar Zone. In order to determine the productive value of the tar zone the Asso- ciated Oil Company suspended drilling at depths Avithin this zone after, in each case, making an upper water shut-oft' in wells Xos. A-61 and A-71 and pumped them for test. The following are the results of these tests: Test in A-61— September 26-Oetober 9, inclusive: See progress chart.

It will be noted from the foregoing that well No. A-61 showed a con- siderable production from the tar zone. This production is very heavy, however, 8.1 deg. Banme, and, although it is advisable to conserve the oil, it undoubtedly should be segregated from the production of the oil zone which, if it were not for the fortunate advantage of coming hot from the ground (130 to 140° F.) would be difficult in itself to handle.

Because much of the oil is heavier than water, in corrected gravity 8.2 to 9.8° Baume, tliere has l)een some speculation as to the prob- able relative positions of oil and water in these wells. It is known that in the sump holes it often happens that water will be on top of the oil. Considering the high temi)erature of the oil while in the wells, however, resulting in an increase in volume, and the fact that there is consider- able gas mixed with the oil, there would seem to be litt](» question but that the oil will rise to the top of any water in the wells. Sources of Water. The source of the large quantities of water, shown on the production reports, has not yet been satisfactorily determined. Some of the representatives of both companies are inclined to the opinion that most of the water, showing in production, comes from the water zone, that is, from known water strata above or in the tar zone. If such is the case this water must enter the wells througli : (1) Faulty shut-offs. (2) ('ari-ied do\\ni behind a water sti'ing into a fracture zone and thence working its way througli crevices and fractures, ai'ouiid and lielow the shut-oiif. into the oil zone. (3) Lack of uniformity in shut-offs. For example, walcM- is cai-ried to a much greater depth, with 12^" strings, in Soladino wells Nos. 1, 2 and 3 than in Soladino wells Nos. 4 and T). or Arrellanes wells A-61, A-71, A-80, A-SL The production record of Soladino well No. 2, however, does not indicate that any great amount of water has been so carried to the lower oil formations. On the contrary, it lends support, along with the following evidence, to the probability that the large quantities of water are coming from the bottom of the oil zone. Soladino Well No. 2 is one of the sliallowesl wells in Ihc gi-oup. It luis always been a coniparativfly dean prodncei*. Soladino Well Xo. .1, as lias already been shown, and reference to the foregoing production reports will give h\Wr details, produced large quantities of water during portions of March and April, l!)17. On April 18, 1917, the work of bridging this hole, for the purpose of cementing a string of 10'' casing, stratigraphically uniform with other shut-oflPs near the shell at the top of the oil zone, was started. On May 1, 1917, this hole liad l)een bridged to 1. ").")<;'. The 10" casing ha.s not been cemented to date, although it is the com[)any's intention, at this writing, to plug the well in bottom and cement the 10" casing, later. The well was again put on pump in May, 1917, and the subsequent record is for production of tluid supposedly taken from above the bridge. :^82 STATE OIL AND GAS SUPERVISOR. It will be noted that since the well wa.s bridged the water production has greatly decreased. It therefore would appear that much of the water produced in March and April, 1917, came from a depth greater than 1556 feet (top of the bridge). It is possible that some, if not all, of the water now coming into the well, has its source in the water zone, back of the V2V' easing. There is also the possibility that part of the production, showing in the well, comes from below the bridge, if the bridge is not secure, and that the bridge exerts sufficient back pres- sure to control the fluid below a depth of 1535' and hold back most of the water which usually appears when any of the deeper wells are produced unrestrainedly for a considerable length of time. There appears to be a condition in which the oil immediately available to a hole from its surrounding reservoir breaks in. The folloAviug portion of a production record of Soladino Well No. 7 is typical of the behavior of the wells that produce large quantities of water : Bbl. oil r.bi. water IS „ _ . 1 3(5' • 2-10 fKl 50 sm 160 40 October i^ - . .

Although there are no data, as to dates at liand. it is known that Arrellanes Well No. A-80 suddenly turned to large water production the fir-st time it wa.s pumped for a number of days and that after the well was shut down and pumping again resumed it produced clean oil for a time. In each of the cases of this kind the water produced was hot. Tem- perature readings made at lead-line in Soladino Wells No. 3 and 4, under similar beliavior, showed 142 and 138 deg. Fahrenheit, respec- tively. Analyses of Water. Chemical analyses have been made of a number of samples of the hot water. Samples of water taken from shallow depths, in the Avater zone have also been analyzed, although none of the later type have been taken from wells in the line-group.

A dose reseiiihjanee will be noted in the contents of the three ''Hot Water" samples, also in the contents of the three "Water Zone" sam- ples. Casual inspection indicates that they are two different types of water. This is especially noticeable in the difference in the magnesium and calcium carbonate content of the two types. It remains, however, for the chemist to determine whether or not waters of the type from the "Water Zone," moving down through the tar and oil formations, would be transformed chemically into the "Hot Water" type with the possible evolution of the rather extraordinary amount of heat. Such a transformation would be necessary, in order to satify the theory that the large quantities of hot water are supplied from the strata in the water zone. Plugs. A study of the progress chart, attached hereto, will show that a numlK'r of the wells, namely, Soladino No. 8, Soladino No. 4. Arrellanes A-80, and Arrellanes A-91 have been plugged in bottom with the hope of excluding the large quantities of hot water. That these plugging operations have not instantly benefited these particular wells can be explained by a study of the character of the oil zone. The shales are fractured or creviced. (As an illustration, mud, used to establi.sh circulation in Soladino No. 5, when the well was bridged to cement a string of 10". appeared in adjoining wells.) If water is present in large quantities in the lower part of the oil zone, then, as long as the bottom of any well lies open to this water the pro- duction of all the deeper wells of the group Avill continue to be affected. ,■584 STATE OIL AND GAS SUPERVISOR. Remedial Work. Therefore in order to systematicall.y eliminate tlie possible water sources the following program should be followed: (1) All wells in the group should be plugged to a uniform strati- graphic position. The present production in Soladino No. 1 is probably coming, from above 1535 feet and in Soladino Xo. 2 from above 1565 feet, and this is an indicator as to proper plugging depth. (2) A stratigraphically uniform shut-off .should ])e made in all wells at the bottom of the tar zone. (3) Steps should be taken to remedy the discrepancies in uni- formity of shut-off at the top of the tar zone. Operations under the first two items have already been recommended, for various wells, by this department. Mud Seal. It is the deputy's opinion that in future work in the group attempts should be made to build mud, by pumping mud laden fluid under pres- sure, into the creviced, fractured, cavy and rotten shales, which take large quantities of water and undoubtedly become channels for percola- tion and the migration of waters, from their native formation.s, at ran- dom through the area. The Doheny-Paeifie Petroleum Company is using hydraulic lime to a large extent in present cementing operations. No hydraulic lime was used in any of the wells of the group under diseusrsion. The hydraulic lime fluid is pumped ahead of the cement fluid. It goes into the well and back of the easing under very little pump pressure. Usually, dur- ing the placing of the lime and cement fluid, complete water returns are gotten at the top of the easing. Under such conditions the best that can be said for the lime is that, when it sets, it will make a veneer on the walls of the hole and po.ssibly assist in producing a bond with for- mation for the cement wliich follows it. Without applied pressure very little lime or cement will find its Avay into the crevices and fractures, unless, of course, as in the case of A-52, already mentioned, circulation with returns can not be established. And. in that ca.se. the fact that water was returned, on testing, from formations near the shoe shows that the .sealing effect of cement, wasted into formations while cementing, was practically negligible. The crevices and fractures should be filled, and rendered impervious, prior to cementing. The mudding operation should l)e immediately followed b}' the cementing operation, an excess of cement fluid being used, so that the first of the cement fluid will displace the mud between the casing and the wall of the hole. In the mudding operation it might TIIIKI) ANNIAl- I^KPOKT. .>N.) 1)0 noccssiiry Id use sawdust oi- .souk* other in;it*'ri;il with the mud, to assist in estal)lishiii^ a el()«r or tiller tor the aeeuniidation of the clay in th<' porous formations.

Pumping test, as recommended in Report T 3-90, showed that the well produced 10 barrels of oil and 10 barrels of water per day. The company proposed to put in a string of 63" casing, and cement at the top of the third oil zone. Proposal to cement string of 6i" casing was approved with the recommendation that the •shut-off be made at a depth of about 3Tr»0'. The company stated that they believed that the recommended depth of shut-off was too deep. The company's attention was called to the fact that average distance from the top of the second oil zone to the top of the third oil zone is 550' to 60O' in this locality. It was noted that in deepening to the third zone the usual procedure, with some exceptions to be men- tioned hereafter, has been to cement a string of casing at the top of the third oil zone. It was also noted that in Harris Well No. 3, the 8]" casing was cemented at 3457', or 247' below the top of the second oil zone. It was pointed out that in wells Nos. 6 and 17. Newlove. and No. 14 Graciosa. shut-offs, for the purpose of excluding second zone oil and water, had been made at depths considerably shallower than the shut-offs in most of the wells of the grou)). Study of the production data of tlie sixteen third zone wells of the group, showed that the three wells mentioned were wet wells. It was noted that in each of the three wells mentioned, a shut-oft' was made because of the good oil showing in sand supposedly at the top of the third oil zone proper. There were sufficient data to show that the sand thus included in the third zone production of Newlove wells Nos. 6 and 17 and Graciosa Well No. 14, does not correlate with the producing sand in most of the third zone wells of the group. The top of said sand lies al)0ut 200' above the top of the thiitl oil zone proper. It was. therefore, concluded that water aitpearing in third zone wells of the group, was coming from one of the following sources : (1) Shut-cpffs Udt suc.Tssful in Newlme G. 17 and Graciosa 14. Newlove i", showi'il surrrssfnl siiiit-off iu i.Mni|.ing (est (see Ki'|...rl I'.-^l. .\i>ri! 19. 19171. 'I'li.' 396 STATE OIL AND GAS SUPERVISOR. other wells showed successful tests for slmt-off and this source was thousht to be least probable. (2) That the iut(>rniediate or "stray" oil sand, between the second and third oil zones, above which shnt-ofTs are made in the three wet wells, carries water. (S) That the third zone sand in these wells, beinj; the farthest down the dip, carries edge-water. Tlii« department therefore suggested that the company drill to a dei>th not greater stratigraphically than that at which the intermediate or stray sand is found in wells Xos. and 17 Nevvlove (J>(j()0' to 8(!."iU'), or to such dei)tli, above .'»(►.">((', at which formations would stand up, and put the well on the pump at that depth. It was also stated that if such production test, provided the well were deep enough to engage the stray sand, showed the well to be making no more water, that is, 10 barrels per day, than it did immediately below the 8i" shut-ot?. this department Avould consider it unnecessary to cement another string of casing, providing the hole was finished in such condition, as to liner and other mechanical operations, that another string could be cemented in case the well later developed water, and test showed such a course to be necessary.

Proposal to mud formations and recement either the 12J" casing or 10" casing in this well was approved because of the following conditions reported by Mr. T. A. Collins, superintendent : "After drilling this well into production to a total drilled depth of ISOO'. we put well on pump for production test. We found very little oil and one bailer of water every six hours. Placed plug 20' under 10" pipe and found water had broken in around shoe of 10" casing. We put a strain on 10" casing and with little trouble pulled it loose. When 10" casing came loose the well showed increase of three bailers of water per hour." The 10" casing was originally cemented with 100 sacks cement by the Perkins process and, because of the ease with which the casing was later removed, as reported by Mr. Collins, it is concluded that the cement fluid was pumped into the fractured shale formations immediately adjacent to the shoe of the 10" casing. The company's proposal to mud the hole, prior to cementing, was made with the idea of sealing these fractured shale formations so that the cement fluid column could later be confined to the space between the wall of the hole and the casing. Well No. 14, Soladino, shut off. T 3-124. This test was witnessed for the purpose of determining probable eflTiciency of mudding operations proposetl and covered in preceding report No. P 3-l(>7. It was reported that about 170 cu. yds. of mud fluid had been forced into the formations adjacent to the 12^" and 10" shoes, that is between depths of 102.")' and 1120', under a closed pressure of about (500 lbs. maximum and during a period of about 20 days. Manure was also used to assist in clogging the porou.s strata. At the time of inspection heavy mud fluid was being pumped down the 10" casing and returned to the surface between the 10" and 12^" casings. The open pressure developed was 200 lbs.

This represented an average of 370 gals, per hour for the entire period, but the water came in much faster after the drilling was done. From the above data it was concluded that the water which entered the hole came from formations below the 8^" shoe and mostly leaked past the bridge. Well No. 3, I^ase 2. drill. P 3-177.

Deputy recommended running casing tester, as there was some old pipe in the hole. Casing tester was placed at bottom at 8:30 a.m. August 2, 1917. Tester was pulled at 11 :30 a.m. August 2d and came up dry. One pound of aniline (red) dye was put into the hole outside the 12i" casing at this time and the deputy recommended that the hole be drilled ahead (dry) 50' with the idea that if the water appearing in the hole were native to formations between the 12*" shut-off the flow would increase as the drill entered further into the shales, or that if there were a small leak around the shoe the dye would appear in the hole. The hole was drilled alicad 50' and bailed to bottom at 9:00 a.m. August 3, 1017. At 7 :00 p.m. August 3, 1917, bailer was measured to new bottom at 1085' and came up empty. Bailer was run again and brought up about two gallons of water and a showing of tar. It was concluded from the foregoing that the water appearing at the initial test was drilling water which, in drilling the 50' of new hole, was completely recovered from the shale« in which it had been absorbed.

In making bailing test for water shut-off with 12A" casing at 900' it was found that the fluid level had risen 521' in 12 hours. The test indicated that another water stratum had been entered or else the shut-off was a failure. However, in view of the fact that no water had been logged at this stratigraphic depth in neighboring wells and 150 sacks of cement had been used for a shut-off, this depart- ment decided that the water was coming into the hole from some source other than around the shoe and strongly urged the company to test casing for collar leaks due to insuflicient tightening. The company ran a casing tester and found casing leaking at the rate of 070 gals, per day. The casing was screwed up 20 inches. .After casing was tightened the tester showed one pint of water at a depth of 945' in one-half hour. Well No. 4, Morganti, shut off. T 3-i:'.2. The 10" 40-lb. casing was nnidded and cemented at 1472'. It was reported that the hole below 9G and actually eonfirmed the observation of the Supervisor that water is Howin^- fi-oni behind the easing'. Tlie hearing- was conducted for the purpose of considering the physical facts as to undernrround conditions at International well No. 7, belonging to the Union Oil Company. The facts are developed by stud^- of the observed conditions in wells of the immediate vicinity, and are as follows; 1. There is an anticlinal fold in the formations underlying the land in question. The axis of the fold runs southeasterly through a point near International well No. 4. The axis of the anticline plunges or becomes lower as it is followed toward the southca.st. 2. The number of strata carrying either water or oil is extraordinarily great and presents one of the most difficult problems encountered in California, so far as pro- tection of oil sands from damage by water is concerned. However, detailed and careful study shows remarkable persistence and regularity of geological conditions. There are no less than nine .separate and distinct beds of sand carrying oil and occurring within a vertical x'ange of about 00<> feet. There are at least three strata or groups of strata carrying water. For convenience of description, the oil-bearing strata have been grouped into three zones. The water-bearing zones have been chosen as the division lines between the three oil-bearing zones. Zone "A" is the uppermost or top oil sand, and is less than 100 feet in thickness. I>ess than 50 feet above it is a zone carrying water and referred to as the '"lowest top water." Zone "B" is almost lOO feet below zone "A," and is nearly 200 feet thick. Between zones "A" and "B" is a water-bearing zone referred to as the "upi>er flow- ing water." Zone "C" is about 400 feet thick, and is about 100 feet below zone 'B." Between zones *'B" and "C" is a water-bearing zone referred to as the "lower flowing water." o. Zone "A" has been encountered and identified in at least twenty-three wells on portions of Sections 4 and .'i, T. 11 X., 11. 2:\ W., and Section .12, T. 12 X., R. 23 W.. S. B.

I*. & M. One well, namely. International Xo. 1, directly upon the said International property, encountered and actually pro- duced oil from zone "A." Testimony of witnesses was iiractieally unanimous in the opinion that zone ".V" extends under the International property. At least twenty-two of the wells in the aforesaid sections 4. ."• and ;>2, have jini- duced oil from zone "A." The total prod\iction has lieen not less than 1,4.'>."..17". bbl. of oil ranging from 1S° to 22° Baume. The average daily production of individual wells ranges from .'iS to ."»00 bbl. of oil. There have been about 4!Hi.41T bbl. of water lifted with the oil from zone "A," or about one bl)l. of water to every three bbl. of oil. The thickness of the i)roductive oil sand in zone "A," as reported by logs of wells, ranges from 'A to 20 feet, the average being 10 feet. 4. Zone "B" has been encountered in at least nine wells in said Sections 4, "» and ."2. Five of the wells have produced a total of at least 1,220,S.">0 bbl. of oil ranging 27 41S>)4 418 STATE OIL AND GAS SUPERVISOR. fi'om 24** to 2G° Baiimo. The average daily production of individual wells ranges from 50 to 520 bbl. of oil. There have been about 224.002 bbl. of water lifted with the oil from zone "B," or about one bbl. of water to every six bbl. of oil. The thickness of the productive oil sands, as reported by logs of wells, ranges from 6 to 1.5 feet, the average being 10 feet. 5. Zone "G" has been encountered in at least 20 wells in said sections 4, 5 and 32. Twenty-four of the wells have produced a total of at least 12,175,."V.")0 bbl. of oil ranging from 18° to 27° Baunie, most of it being above 24°. The average daily production of individual wells ranges from ."> to 30,000 bbl. of oil. There liave been about ],211.90.') bbl. of water lifted with the oil from zone "C," or about one. bbL of water to every 10 bbl. of oil. The thickness of the productive oil sand, as reported by logs of wells, ranges from ('» to SO feet, the average being 22 feet. 0. Kecords of drilling operations show that at none of the wells drilled by the I'niou Oil Company on the International properly were proper and sufficient tests made for the purpose of proving or disproving the presence of zone "A." The Com- pany states that considerable sums of money were spent in conducting tests and trying to locate zone ''A." but in the face of records showing that water had access to the formations at thi' lime search was conducted, it would have been difficult, if not impossible, to establish the nature of the formations. It is not an uncommon occurrence for wells to pass through productive oil formations without discovering their nature, and the mere expenditure of money can not be considered as a detailed test or search. Furthemiore, diligent inquiry on the part of the Supervisor has failed to disclose that the Union Oil Company made careful geologic study and com- parison of well logs in the locality. Thorough geologic study has been shown to be a neces.sary step in the discovery and identification of zone "A." Such a study would necessitate data accurately locating all wells and showing their elevations, and as the Company could not furnish the Supervisor with such primary information, ^ve are justified in stating positively that the Company had not made careful geologic study and comparison in the effort to locate zone "A." The large production obtained from zone "C" is ample explanation for a oolicy ■which would temporarily disregard the possibilities of smaller profit from zone "A," find earnest, but misdirected, efforts to find zone "A" might readily lead to a; belief that it did not exist. There is, however, ample evidence both of the existence and value of zone "A," and the Supervisor is therefore not justified in approving methods of drilling which do not protect it so far as possible from water. It is not the intention of the Supervisor to insist that the Company shall produce from either zone "A- or zone "B." 7. The cost of casing is the largest single item of expense in the drilling of wells, and is sometimes increased where extra precautions are taken to protect formations from water. In this locality, however, a comparison of casing costs at seventeen wells shows that wells which definitely located zone "A" before drilling to zone "C" each cost, on the average, .$2."i4 more than those which did not definitely locate zone "C." The average cost of casing in the latter case is .$22,035, and therefore the increased cost is about one per cent. S. It is impossible, under methods previously followed, for the Company to cor- rectly determine the nature of formations passed through in drilling. This is dem- onstrated by comparison of the logs of International wells Nos. 2 and 0. which are located less than 30 feet apart, but fail to record the same formations, although it is practically a certainty that actual conditions in the wells are not only similar, but identical. 9. As has already been shown, water in considerable quantities and proportion has been given access to zone "A." Therefore, some damage to the zone has already been done, and in the light of other similar conditions, the damage may at any time reach great proportions. Protective measui-es can not be postponed awaiting over- whelming damage. 10.

(.'oinpnuy show larger amounts of water than most of tho other wells within the neifrhhorhood. This con- dition may directly affect the well covered hy this order, and notice is hereby given that the Supervisor will expect proposals at an early date looking to the testing and repairing of various International wells. When water trouble develops at a well, the first and most obvious i)lace, in the ai)sence of other evidence, to look for the cause, is within the well itself. CONCLUSION. The present shortage of oil, as well as casing, gives cause for serious reflection before the issuance of an order which either postpones the production of oil or requires an increase in the amount of casing to be used. On the other hand, the protection of the oil bearing deposits is of prime necessity, particularly at the present stage of national neces- sity. It is believed that more prompt and satisfactory agreement between an operator and the Supervisor can be arrived at by less formal methods than have been followed in this case, providing the operator is prepared to meet the Supervisor in the matter of co-operation in the necessary engineering and geological work. As previously intimated, the Supervisor is prepared to insist that the highest standard of oper- ating methods shall be followed. In fairness to the Union Oil Com- pany, it may be said that certain of its statements and actions, not con- cerned in the matter immediately under consideration, indicate that in future their work will be preceded by technical investigation and direction equal to the best usage of other operators and therefore equal to the standard required by the Supervisor. Conditions at International well No. 7, as .shown by proposals, reports and correspondence passing between the company and the Supervisor, are as follows : The Company proposed (August 21. 1017) to drill the well to encounter oil sand (zone "C") at a depth of 3.37.") feet; water to l)e shut off by cementing 10-inoh casing at a depth of 21XX) feet and 81-inch casing at 3.300 feet. The Supervisor r.ecommende70 feet and the bottom of the hole at 2840 feet, the Company (January 13, 1018) propo.sed to li'st for water immediately below the lf>-in(h casing, and. if no water was found there, to make another test for water with perforated casing open to a depth of 2840 feet. If the latter test showe feet. No mention of test or protection of zone "A" was made. The Supervisor (.January 17. 1018) ajiproved the two proposals to test for water, but in addition recommended that if it were found, which contingency was not covered by tlie proposal, it should be shut off by cementing Sj-inch casing at 2S40 feet. • It was also recommended that, with water either absent above or shut off at 2.84<^) feet, the well should be drilled to a depth of 2875 feet and teste of . e J>rM'ns ■"*■// • fr^c/uc/^y /Ve// 32' rtidlond a///'e/cis • C/ Dora O// Co a/Co ■' Co/, ^mer/^cmu/c c/ ■ C,/Cc a/Co ^C3 £>.

B. B. & M. March 6, 1917—10'' casing cemented at 2904' with 400 sacks cement. The cement apparently satisfactorily placed. 10" casing tested, and water found not shut off. April 12, 1917 — Pumped about 10 sacks of cement into fornui- tion at shoe of 10" casing, under 600 lbs. per square inch pressure. April 20, 1917 — Tested, and found water not shut off. May 7, 1917— Ripped hole in 10" casing at a depth of 2824' and bailed to 1200', and on May 8, 1917, found water at original level and 100' of fine sand in the hole. May 12, 1917— Pumped cement into rip after pumping about 500 bbls. of mud into formation through the rip. Final pressure 600 lbs. per square inch. Ripped hole in 10" casing at 2798' (opposite supposed upper oil sand. Attempted to pump water out through rip at 2798' but failed. Assumed that cement had pro- tected top sand and proceeded to drill well into Zone "C." The next larger string of casing in this well was landed at a depth of 530' and the only other methods that might have been folloM'ed to insure protection to the top sand, would have involved either drilling out through the 10" casing with 8" casing above the upper sands, or re-drilling with 10" casing from a depth of about 530'. Southern Pacific Company (Fuel Oil Dept.) Well No. 31, Sec. 5. T. 11 N., R. 23 W. JMareh 24, 1917— Cemented 11§" casing at a depth of 2545' w^ith 7 tons. Cementing approved as satisfactory.

In the Matter of the Appeal of the Union Oil Co. to the Oil and Gas Commissioners of the State of California. At a meeting held in Taft, California, on April 9, 1918, in reference to the proper completion of Well No. 7 on Section 4/11/23, owned by the Union Oil Co. of California, at which meeting the Oil and Gas Com- missioners of the Fourth District of the State of California were invited to attend for the purpose of hearing the evidence given by the California State jNIining Bureau, which was represented by R. P. McLaughlin, Supervisor, and his deputies from the various districts of the State of California. Also evidence given by the Union Oil Co. of California which was represented by G. Kamerer, superintendent in this District and various employees, also evidence given by the Lake View No. 2 and Interstate Oil Companies, of this District, which was represented by Mr. Roy Evans, their superintendent and various employees; also evidence given by the Pat Welch Oil Co. of this District, whicli was represented liy Mr. R. R. Pollack, its superintendent. On the twenty-seventh day of April a hearing was lield on appeal to the Oil and Gas Commissioners and said appeal having been taken by the Union Oil Co. from the order made after the hearing on the ninth day of April, 1918, by R. P. McLaughlin, Supervisor of the California State Mining Bureau, and we, the Commissioners to whom said appeal was taken, hereby make the following findings and order in said matter. 1. That the above companies now own and are operating wells located in the northeast quarter of Section 4/11/23. 2. Also to witnesses not directly connected with the above companies. 3. After hearing the evidence and the explanations of the Peg model by Mr. R. N. Ferguson, Deputy Supervisor of this District, in connec- tion with the dilferent methods of drilling by the different companies, also to the method of cementing and mudding off water and oil sands, which in certain depths, lie in close proximify. fi'om the difficully tlieso dift'erent oil companies encountered in drilling wells in tliis locality. 4. Also, takng into consideration the gravity of the situation as regards making reconunendations for the drilling of wells in this or any other locality, to protect all oil sands from the infiltration of watiu", which, is very essential to the producing of oil in this immediate locality or in any other locality. 5. From the evidence given by the different witnesses, they have adopted, what we would consider, a very good plan of mudding and cementing all oil or water sands encountered or which might be encoun- tered. 44f) STATE Oil. AND OAS SUPERVISOR. G. From the evidence given by the ditlferent witnesses during this hearing, on quite a number of occasions, there has been oil sands encountered and either pumped dry or became infiltrated with water. These wells have been deepened by permission from the State Mining Bureaii of California, to proceed to a deeper sand which underlies the first oil sand. 7. From the description of the sands by the State Mining Bureau of (Jalifornia, these sands are described as Zone A or first oil sand, Zone B or second oil sand and Zone C or third oil sand. 8. The Lake VicAv No. 2 and Interstate Oil Companies liave liad some very productive wells from the first zone or first oil sand. 9. From the evidence of the various witnesses, directly under the first oil sand, is what they call a flowing water, which, if encountered and not shut off, would practically ruin the first oil zone. 10. From the evidence taken at this hearing, there was a meeting called some time ago in the S. P. Company's (Fuel Oil Dept.) Office at Kerto, by the different oil companies located in the N.E. ^ of Section 4/11/23. At this meeting, there was also a representative of the Cali- fornia State Mining Bureau. 11. They took up the matter of tlie best method to pursue after deepening wells from the first oil zone to a deeper zone. They finally decided that they could land another string of casing about 400 or 450 feet below the first oil zone and force enough cement behind this casing to extend through the upper oil zone. Also, through the flowing water encountered directly below this oil zone, sealing off all oil and water encountered above the lower casing shoe which would be approximatelj'- 400 feet. 12. From the evidence taken at this hearing it would appear that it was necessary to have a string of casing landed in close proximity to Zone A or first oil sand to tie to when making the next cement job. After commissioners have deliberated on the evidence for some time it was decided that a string of casing landed in close proximity to Zone A or first oil sand Avas a very good idea but on the other hand did not deem it necessary to make a good cement job and decided they would rather have enough room between the first oil zone and casing landed above first oil zone to pump enough cement to cover any oil sands below casing shoe to protect sands from infiltration of water but not have cement to come in contact with casing above Zone A or first oil sand. 13. From the evidence given at this hearing it was very clearly defined that this process which they had adopted, of cementing, had proven very effective due to the tests of oil made for water produced from the various wells before and after these various wells were drilled to a lower zone. THIRD ANNUAL REPORT. 447 14. From the evidence given at this hearing by the different wit- nesses, the water infiltration into Zone A oil sand from any water encountered while drilling below Zone A or first oil sand, was really nothing more than could be expected from the oil produced in the period of time which intervened between the time the first oil sand was encountered and the drilling and producing oil from Zones B or C. Therefore, we think, that the amount of cement these wells were cemented with had effected a very good seal to any and all water encountered below the first oil sand. Also, it must be remembered that the wells that were drilled to a lower depth, either Zone B or C, were not being produced from Zone A. 15. The International Oil Company of California have drilled several wells on their parcel of land in the N.E. ^ of Section 4/11/23, and from the evidence given at this hearing, the Union Oil Company of Califor- nia had purchased this land on the strength of a well drilled on this parcel of land, knoAvn as Coronation No. 1. 16. At the time this purchase was made, this well was flowing some oil and water. The Union Oil Company started their development work shortly after purchasing this property, and from the evidence given at this hearing, expended in the neighborhood of $214,000.00 trying to locate Zone A or the first oil sand, which the Interstate and Lake View No. 2 and Pat Welch Oil Companies were producing from. After repeated effort to locate this sand, they finally decided to aban- don the idea of ever locating an oil sand known as Zone A. And, from the recommendations by them to the California State Mining Bureau, they were allowed to proceed to deepen these wells to a depth sufficient to satisfy them whether there was a lower Zone or Zones, which, they after^vard discovered to be known as Zone B and C in that locality. Several wells were drilled which proved very productive. 17. From the evidence given at this hearing, the Union Oil Company, before landing what they called a water string at a depth of approx- imately 3000 feet, did mud up and pump in enough cement behind this string of casing to seal off all water and oil if any were encountered, far enough back above Zone A to protect oil sands operated and produced by any other companies on the N.E. | of Section 4/11/23. ]S. From the evidence given at this hearing, it would appear to us that this has been very effectually done, due to the small increase of water from the first oil zone or zones during a period of several years. 19. The Union Oil Company's Section 4/11/23 well No. 7 was drilled to a depth of 2840 feet with a 16" rotary bit from top of hole to bottom. While this company was putting in their 10" casing, this eas- ing became tight at 2570 feet ; so tight, that this easing could not be loosened after making repeated attempts. They afterward tried for 448 STATK GIF. AND (iAS SUI'ERVISOR. circulation behind this casing, which they got. and pumped in ITH) sacks of cement. After leaving- hole stand cemented for a certain length of time, they tested ont this well for water. 20. After cleaning ont this well through the shoe and testing for water, they found they could not lower water below the water level. They decided they had either encountered water below the casing after this well had been drilled 2840 feet, but easing was landed and cemented at 2570 feet, or water was coming around the 10-inch shoe. 21. The Union Oil Company requested permission from the Califor- nia State Mining Bureau to proceed with this well to a depth of 3300 feet with 8:{-inch casing. Before casing was landed at 3300 feet, they were to pump enough cement behind this string of casing to come back far enough or to the bottom of the 10" casing, which was landed at 2570 feet and to cement off all water sands that had been encountered below that depth. This request was refused by the State Mining Bureau. The Union Oil Co. then requested permission to land a string of 6|-inch casing at 2840 feet, cementing same. After cement had set long enough, to guarantee its hardness, they were to make proper tests witnessed by the State Mining Bureau of California as to its virtue. After the State Mining Bureau had accepted same as dry, they were to proceed with the drilling of this well to a depth deep enough to determine it Zone A extended through the property or to this well. This proposal ,vas also rejected by the State IMining Bureau. 22. We, as a bod3'' of Commissioners, who represent the Oil Industry of the Fourth District of the State of California thought that test referred to in paragraph 21, would have been a very good test to deter- mine for all times whether Zone A extended to this property in paying quantities, as the Union Oil Company had endeavored for several years prior to this time to develop this Zone A or first oil sand. 23. After the Commissioners of the Fourth District of the State of California had heard the evidence given in reference to the drilling of wells which had been drilled and produced from Zone A or first oil sand, also had been drilled through Zone A and produced from the lower Zones and the proper methods had been pursued w^hereb.y the top Zone w'as protected from water by the mudding and cementing process, we, the Commissioners of the Fourth District of the State of California, have agreed that the drilling of Section 4/11/23 Well No. 7 on the N.E. -] of this section, should be drilled to a depth of 3300 feet, using 8|-inch casing, and that enough cement should be pumped behind this string of 8|-inch casing to reach to a height of not less than 2700 feet, and that after this cement has been pumped in the hole of a sufficient quantity, that cement is followed up with mud of a sufficient weight to THIRD ANNUAL REPORT. 449 approximately counterbalance the weight of the cement so that after the easing is landed at 3300 feet, no cement could force its way back into the casing. This, we, the Commissioners of the Fourth District of the State of California, think would make a very practical and good cement job, to protect any and all oil sands, if such oil sands exist between the depth of 2570 feet where 10" casing is landed and 2875 feet where oil sand, if any, might be encountered. 24. This well No. 7, at the present time, has a hole drilled to 2840 feet by a 16" rotary bit, leaving a hole below the bottom of the 10" cas- ing, which is landed at 2570 feet, of 270 feet, whicli is 16" in diameter. From this depth to a depth of 3300 feet this hole should be drilled with a 10" rotary bit. 25. From the order issued from the Mining Bureau wherein they recommend the International Oil Company to develop this well from 2840 feet, after 6^" casing is cemented at that depth, they suggest the drilling of 15 feet at a time and testing for oil and water, and continu- ing this test by drilling 15 feet at a time, until oil or water is encoun- tered. This is unsatisfactory. 26. After the commission had deliberated on this order for some time and the commissioners all being practical men they decided that this method would be impracticable and almost impossible to keep casing free and make these tests every 15 feet. Therefore, we the commissioners of the Fourth District hereby order that the Union Oil Company, or International Oil Company, drill said hole to a depth of 3300 feet using ^\" casing and pump sufificient cement behind this string of 8^" casing to reach a height of not less than 2700 feet and that after this cement has been pumped in the hole that they follow up with mud of sufficient weight to counterbalance the weight of the cement so that after the easing is landed at 3300 feet no cement could force its way into the casing. This method was testified to by Mr. Evans of the Lake View No. 2 Oil Company and ^[r. Pollack of the Pat Welch Oil Company, to be practical and vei-y satisfactory. It is further ordered that the Union Oil Company shall mud off all sands as encountered under pressure of 400 pounds per square inch at the surface, or to such times as the sands shall take no more mud, to a depth of 3300 feet or at the point easing is to be landed. It is also ordered that at the time the cementing is to be done, that the Union Oil Company notify the Deputy Supervisor so that a repre- sentative of the State Mining Bureau and a representative of the Oil and Gas Commissioners of the State of California, be present and that in the event of any mechanical failure during the pumping of this mud and cement, whereby a sufficient amount of cement can not be pumped 2»-418M 450 STATE OIL AND GAS SUPERVISOR, • behind this casing to seal off all the sands encountered below the depth of 2570 feet, the' matter to be taken np immediately with the oil and gas commission for its consideration.

Three months after completion of the well, in a manner disapproved by the engineering staff of the State Mining Bureau, It is producing considerable water and has actually depreciated the value of the entire property. The total production of the property during three inonths prior to completion of the well was 136,840 bbl. of oil, while during an equal period of time since its completion the total oil production has only been 112,684 bbl. SUNSET FIELD. • The extent of this field has been somewhat enlarged by the develop- ment of production by the Standard Oil Company on Section 7, T. 11 N., R. 23 W., S. B. B. & M., and the Midway Oil Company on Section 35, T. 12 N., R. 24 W., S. B. B. & M. Peg models on a scale of 100' to the inch, both vertical and hori- zontal, have been constructed covering a portion of the Maricopa Flat and as a result the information on this area is mucli more exact than it was previously. A contour map of the first oil sand of Zone A has been prepared and has proved invaluable in determining the proper point of shut-olf in new wells. The composite log (p. 424), made up by combining some typical logs graphically, has been used with excellent results in predicting the depths of the various sands below the top of the first oil zone. BELRIDGE FIELD. Careful operations in this field by the General Petroleum Corpora- tion and the Marina Oil Company have successfully overcome a very difficult water situation and have developed a good production from shallow depth. The method used by these companies of thoroughly testing the formations penetrated, as the hole is drilled, are worthy of emulation by many other operators. In this testing much use is made of a temporary shut-off above the sand to be tested, KERN RIVER FIELD. The year has not been marked by any great improvement in water conditions in the field. Several companies in the vicinity of the old West Shore property in Section 32, T. 28 S., R. 28 E., M. D. B. & M., have by mutual agreement THIRD ANNUAL REPORT. 451 l)ersistently sought for an offending well in the hope that by plugging it their water troubles would be eliminated. At the end of the year the work has not shown any results after several wells have been tested. Commendable as this spirit of co-operation is, it is believed that much time and money might have been saved by a thorough investigation of llie early records as well as of the underground structure before the work was begun. Such an investigation is being made or has recently been completed by the geological department of tlie Standard Oil Company and there is little room for dtiubt that if the recommenda- tions of the investigating engineers are followed the source of the v.'ater will soon be apparent. The Associated Oil Company has begun an extensive engineering investigation that will undoubtedly yield big returns. To date no repair work complying with the recommendations of the engineer has l)een begun, but we are informed that such work is to commence shortly. Investigations. Investigations by this department have not reached completion dur- ing the year, but the following work is under Avay: In Kern River field a cross section was made by the dei)artment along the line between the Associated (Kern) and the Peerless Oil (Company properties showing line wells of botli companies. Prints of the cross section were furnished both companies for their use in con- nection with a proposed campaign to shut off water. A peg model of the N.W. i of Section 31, T. 28 S., R. 28 E., M. D. B. & M., was constructed, but no further work has been done towards completing the investigation of that area. A further investigation of conditions in the vicinity of the Amaurot and Del Rey Oil Companies property in Section 5, T. 29 S., R. 28 E., ]M. D. B. & M., was undertaken and brought nearly to completion, but work on it had to be suspended. In this hivestigation a peg model and complete cross sections were constructed, all ba.sed on a stadia survey of the property made by this department. An extensive study of the available records of the wells involved was also made and it is expected that it will be possible to issue a report by tlie first of the year. MIDWAY FIELD. On page 261, Bulletin No. 82, a proposed investigation of the 'J'wenty-five Hill area was announced. Since that time a peg model has been constructed of Sections 25 and 26 and jjortions of 22, 23, and 24, T. 32 S., R. 23 E., ^1. D. B. & M., and a close study of all available records of all wells on Sections 25 and 26 has been made. A complete report on the last two sections will be issued as soon as passible. 452 STATE OIL AND GAS SUPERVISOR. Sections 25 and 26, T. 31 S., R. 22 E., M. D. B. & M. The fact tliat operations were being carried on in this vicinity with no regard for uniformity in depth of shut-off has been recognized by this department for some time. The suggestions of the department as to establishing greater uniformity did not meet with universal favor and it was necessary to compile all available data to bring out the facts. Peg models have been completed of 1280 acres in this vicinity and the resulting information is such now that a great deal of assist- ance can be given the operators in the vicinity. Requests for Investigations. Requests have been made by owners and operators for investigations in the following cases : Under date of January 7, 1918, a request was made by the following operators for an investigation of the water conditions in the vicinity of their properties in the McKittrick field. Claude Pearson East Puente Oil Co. J. H. Crafts Berry & Keller Oil Co. J. A. Pickle .Tewott Oil Co. Roy Fry S. P. Co., Fuel Oil Dept. P. E. Bowles, Jr. Reward Oil Co. A previous preliminary examination of the records of the area had shown that the records filed were insufficient for the purpose. To make this investigation it will first be necessary for the Department to go out and gather the necessary logs. It will also be necessary to make a propertj^ survey in order to get sufficiently accurate informa- tion from which to construct peg models and cross sections. Owing to the fact that a number of investigations having priority over this request have not yet been completed, this one has not yet been acted upon. On May 9, 1918, the State Oil and Gas Supervisor instructed the deputy to start an investigation of the water conditions existing in Section 16, T. 32 S., R. 24 E., M. D. B. & M. A property survey was made of this section and some surrounding territory and a peg model was constructed. As a result of this work the department has been able to make a contour map of the first gas sand throughout a portion of the Buena Vista Hills Avhich has sho^^^l some quite unexpected structure. The development of production from this gas sand in Midway Gas Company, Well No. 60, Section 15, T. 32 S., R. 24 E., M. D. B. & M., has led to the discussion of the advisability of shutting upper water off above this zone in all new wells. A conference of operators was held at the office of the State Mining Bureau after the close of the year to consider the subject. At this conference it was decided that the deputy should outline the area within which it appeared advisable to make the shallow shut-off uni- THIRD ANNUAL REPORT. 453 form. The investigation on which this is to be based is not yet com- pleted. On March 28, ]918, the State Oil and Gas Supervisor requested tlie various companies oix'rating in the vicinity of Section 14, T. 32 S., R. 23 E., M. D. B. & ]M., to outline their knowledge as to the under- ground structure in that vicinity and to submit to him a statement as to their desires in tlie matter of j)ru1('cting certain sliallow oil sands in future drilling. We understand that the companies are co-operating in this investigation and that a report is to be submitted within a few months. Complaints. Under date of Januai-y 12, 1918, the Sunbeam Oil Company, operat- ing in Section 52, T. 29 S., R. 21 E., M. D. B. & M., made complaint against the United Western Consolidated. Owing to the great amount of unfinished work before tlie department tlie investigation requested lias not yet been undertaken. On January 31, 1918, complaint was made by Howard INI. Payne, Receiver for the Recovery Oil Company, Section 25, T. 31 S., R. 22 E., M. D. B. & M., against the Visalia Midway Oil Co., in the same section. The particular well complained of was No. 6. Peg models of the area in question have been construeted and the investigation has been begun. DECISIONS. NORTH LOST HILLS. T. 2.J S., R. 19 E., M.D.B. & M. Section 2. Crescent Petroleum Co.

Representatives of the companies in this locality were called in conference by the State Oil and Gas Supervisor for consideration of the conditions of this well. It was the opinion of these representatives that the condition of this well might result in no particular damage to the surrounding territory. However this decision was not to establish a precedent of low shut-off in this locality. It was further agreed that it be definitely understood that in the future all such pro- posals were to be presented to this Bureau by the companies through their geological departments. The above conference led to an agreement by the geologists of the companies concerned, that they work up and submit a report on the underground conditions in this locality. This report has not, as yet, been submitted. In accordance with the above decision, the proposal to drill tiie well in without changing the .shut-off was approved. Union Oil Co., "Regal."

Of tlie 174 wells in the above talmlation which were deepened or redrilled, 64 were repert'orated, redrilled oi- deepened to increase pro- duction, 90 were redrilled or i)artly plugged to shut oft' water, and in 20 wells packers were set to shut off water. The column headed "Test Water Shut-Oft'" includes reports on inspection of plugs in abandon- ment as well as the ordinary tests for sTiut off of water which with the addition of the work in the field involved the traveling of over 12,000 auto miles. The following data, compiled from the production reports covering the past fiscal year, show average production per well and percentages of idle time and productive operation. The minimum number of wells reported producing was 954, and the maximum number 1174, which includes new wells brought in at various times during the year, and which are, of course, reckoned as nonoperative during the period of the year before being put to producing: Basis 1057.55 well (mean) pumping a total of 349,680 days — Number of days productive operation per well for year , 330.66 Percentage of time of productive operation 90.6 Percentage of idle time 9.4 Average production per pumping day — bbl. oil 47.01 Average production per pumping day — lilil. water 10.64 Total bbl. fluid 57.65 P.asis 1057.55 wells 365 days — bbl. oil 42.58 Kbl. water 9.04 Total bbl. fluid ^ 52.22 I'.asis 1174 wells — Number of days productive operation per well 297.9 I'ercentage of time of productive operation 81.61 Percentage of idle time 18.39 During the year this office was able to supply information to several operators which was helpful in prevention of damage to oil deposits on their own and neighbors' properties. Some of the instances follow: The Shell Company drilled a well on Section 29. T. 19 S., E. 15 E., and estimated the depth to the top of oil sand 45' deeper than the esti- mate by this office. The easing was cemented according to the com- pany's estimate but the cement job failed. After correspondence and discussion the company agreed to put a plug in tlie bottom of the casing and perforate at 40' above the cementing point. This test was made and proved conclusively the presence of an oil sand at or near the point of perforation, giving valuable information for use in future drilling. A notice was received from the Pantheon Oil Company on Section 32, T. 19 S.. R. 15 E., which stated that a well just completed was pro- ducing all water and proposing to test the water string for top water. An analysis of the Avater was also submitted. The company was advised THIRD ANNUAL REPORT. 545 that the analysis showed Ijottoiu water and that a h)Wor sand was- prohahly the source. Siil)se(iuent work iiidicjited that this was the case. The Maine State Oil Company proposed to drill a new well on Sec- tion 31, T. 19 S., R. 15 E., and cement the water string below some oil sands which are not highly productive but which are open in other wells. After this was called to the company's attention the plan of drilling was changed so that these upper sands were protected from water with mud-fluid. The Union Oil Company on Section 8, T. 20 S., R. 15 E., proposed to shut oif water at an old well by cementing the 6|" oil string below a supposed water sand, and to use 4|" casing for the oil string. This supposed water sand is open in neighlx)ring wells and it was recom- mended that the water string be tested for a leak. This was done and a hole was found in the 8^" easing. Most of the water was shut off by placing a packer ou the fi|" oil string, thereby saving a string of casing. DECISIONS. COALINGA FIELD. T. 15 S., R. 12 E., M.D.B. & M. Section 21.

'J'lie amount uf money sliown is the authorized capitaMzation. This information is from tlie records of the State Board of EquaUzation. Star before name indicates that tlie concern produced oil or gas during tlie calen- dar year 1917. The number of wells, followed by the name of a county, means the wells actually producing in said county on December 31, 1917. The Information relative to wells, production, and location is from sworn statements filed with the State Mineralogist in 1918, prior to March 14. This directory contains names of all oil producers, and, in addition, many concerns which are connected with the oil industry, either by mere incorporation or as land- owners. It is difficult to correctly list or classify those outside of actual producers. *A. & J. OIL COMPANY, 400 H. W. Hellman Bldg., Los Angeles, Cal. A. J. Jergins, President. H. J. Haase, Secretary.
