EXPERT TELLS OF EXTENT OF OIL DEPOSITS Paul Prutzman Completes Sur» vey cf the San Joaquin \J <n I f e%\ f v aiicy New Operations Promise to Open Up Wide Area of Territory Detailed Report Made of the Work Now Being Carried Forward Under the direction of State Mineralogist Lewis E. Aubury, a general recosnaisance of tje \u25a0til districts of the San Joaquin valley has just been ccznpleted by Paul W. Prutznan. assistant in the field, and his report has just tees filed , with the state mineralogist. The state tsinieff bureau is now encaged in rrepanr.ir maps of all the different oil districts \n the state and is also at Trcrk on a large re port is which detailed information trill be giren of the different districts. As the work pro fesses general reports will be issued by the !\u25a0\u25a0"'\u25a0!« to the press. . The first of these reports it herewith given. To understand conditions at Ooaiinga It is necessary to bear in mind the topography of the country. From 6-LM-13, which is at the southern ex tremity of the developed field, the foothills run due north for about seven miles, following closely the east line of township rO-14. At the southwest corner of 19-15 they turn sharply to tho east and run almost due east for ulxiut three miles or to the center of the south line of this township, where they again bend to the north. From tli*- apex of the curve thus formed a *pur of the. hills extends in a south easterly direction for several miles. This topographical arrangement ]« ayes, between the foothills and the *pur. a plain ?onip six miles square, Surrounded On three sides by the hills _ 97i<J bounded on the south by the rail toad. The town of Coalinga is on the railroad and close to the foothills and therefore near the southwest corner of Uifa plain, which is smooth and slopes Very gently northwest to southeast. Oil has been found on the lowest por tion of the foothills and extending out for a varying distance from them, on the north and west sides of this plain, s* well as on the outer or valley fare of the foothills where they turn to Ihc north, on 19-13, and on the same Fide of the spur range. The "cast Tirid" is that portion lying on the val- Isy *lope of the north limb, the '•south fast extension" on the east or -valley >lope of the spur. The "west field" lies on the inner portion of the hills west .md south of the plain. The "south field" is the prospective territory south of the railroad, following- the hills for an indefinite distance. MILKS L.OMS "The length of the developed field, ex tendinp from the railroad north, then east, then north again, is some 13 miles. The extension to the southeast Js proved up for a length of approxi mately a mile and a half. The width ,<sf the actually proven belt varies from three-fourths of a mile at the lower extremity to about two and a half miles at the widest part, with an aver age of perhaps two miles. Extension of the Ooalinpa field to t!ie north seems to be pretty definitely ..lyarred by th» operations of the Impe rial of 4-IS-15, which arc said to have ' resulted in dry holes and in finding an order of formation quite different from iliat found farther south. Some main tain, however, that the sands at this point lie farther bark in the hills, and at least one company is drilling on .section S in this township on such a "theory. - To the northeast the operations on 32-19-15 have resulted mostly in water wells, but whether this is due to flood ing of the sands from above <that is, from higher up on the formation), to The difficulty of handling surface water or whether the actual water line has here \u25a0been reached it is yet too soon to tell. To the east of the old wells on 28-19-15 operations are slowly being- pushed farther out, and it does not appear that any limit has yet been set to drilling In this direction. The Fame may be *aid of the work along the outer face n* the spur. Work is gradually being .-carried south and east, and while drill ing here is very deep and correspond ingly expensive, the new well of the Coalinga Mohawk offers encourage- Vitfnt in this direction to operators with means enough to <*arry on this heavy \vork. KSrPIRE'S BIG PRODUCER West of 28-19-15 the new well of the Empire on 32 has bridged, in part at least, the gap supposed to exist be tween the east and west fields and proves up the territory lying immedi ately west. Figuring from the depths of the Limited wells on 29 and of the Empire (some 2,700 feet), it is evi dent that the sands here have a sharp pitch to the southeast and as the form ation on 28 also pitches in the same direction, but on a much higher level, xnore work will be required to finally prove -whether the Empire sands pass under those on 28 or rise again to meet these and form an anticline, and in the latter case whether it will be produc tive on the west slope. There is still a gap of almost a mile between the Empire well and the near est producer on the east. When visited this well was producing about 500 bar ..?ls of IS degree oil, but there was a great deal of sand in the casing and as this has since been cleaned out it seems likely that reports of considerably larger production as present are cor rect. , . The northern line of the old "west vide" field, along the north line of 31-19-15. is definitely marked with old \u25a0work, some of the original Coalinga •wells having been here, but to the South the limit has not been set. The Aztec, in the southeast corner of 31, has lately gone into the first sand, and' both the California Coalinga and M. K. & T. have "lately brought In good producers on 8-20-15. The latter wells are 2.500 and 2,940 feet respectively, which Indicates a normal degree of dip to the sand, both from the north and the west. This work Is the farthest out on the flat, and the old argument as to whether the producing eands extend- across the flat and to the wells on the outer side of the spur is yet unsettled. The 2.800 foot well of the Peerless Consolidated on 10 and the deep test of the Clare niont on 4, said to be 4,100 feet or bet ter, without oil. would seem to Indi cate that the western limb of this anticline will not be productive, which •corresponds well with the theories in Ihe case. -".*_.- BIG EXTENT OF SAXDS On the upper or west side of the west field production has been carried back beyond the. center line of 1 and ,^2-20-14. These wells are shallow, ttuHy 700 to 800 feet, but are good producers of heavy oil, and there is 00 vray or determining how much Coalinga's Consistent Wells Give Promise of Abundant Supply Of a High Quality Product for a Great Many Years to Come CITY EQUIPPED WITH SUBSTANTIAL BUILDINGS, CLEAN STREETS AND MODERN LIGHTING SYSTEM Beautiful Boulevard Extends for Several Miles Through Great Forest of Derricks That Rises From the Leases Most of the San Joaquin valley is rich in soil and beautiful with itr» garden cities. There are great unde veloped sections, bare and baking, that need only water to make them wonder ful. On the west side of the valley are arid alkali stretches, useless even with water, and beyond are the barren lands, disagreeable, dry and devoid of vegetation. It is In just such a region that the oil city of Coalinga was built several years ago. Coalinga was an unlovely city of Hide shacks in an un lovely, dirty field. There was plenty of money.- but -the 'things that money buys were more than 60 miles away. Streets of the town swirled with storms of dust; the roads were frightful. Bunkhouses for the men consisted in most instances of stifling, greasy tents. The conditions were unbearable and the change had to come. The oil producers took a hand in the latter part of 1906 and in 1907; $40,000 was subscribed and a modern, clean, at tractive hotel was erected. The war opened on dirt. Surveyors conquered the crooked streets and an oil spray laid the dust. Things went by leaps and bounds.. Sidewalks were built, a ( lighting system established. Lots were - laid out and houses of pleasing archi tecture were erected by the score. Car loads of cement, steel and brick came to the fields. Banks, halls and fac tories were speedily under way. To day the town would hardly be recog nized by any one who had visited it in Its early stages. Not only has the town gone ahead, but the fields have assumed a different air. Neat bunkhouses, eating houses and roads are everywhere. AYEME AMONG DERRICKS A feature of the. Coalinga fields, a thing inspiring and unparalleled in its wonder, is a stretch of the county road right through the heart of the der ricks. It is not unlike the great high way along the shore of San Francisco's peninsula. It is fully as wide and as good a road, but instead of a meager farther back the profitable s*n<l<? nay ! extend. On |he south side of Los Gatos creek the formation seems to be rather lower than elsewhere along this back edge, and here drilling has been carried back well toward the center of 14. with good results so 'far, and no definite bound to the field so far in sight in this direction. On 25-20-14 the Coalinga western has undoubtedly gone back -to the upper edge of the productive sands, and while work along the east line of 26 has resulted in some good -wollh, It seems doubtful whether profitable drilling can be carried much farther to the west here, unless' indeed a lower sand can be found, of which some in dications appeared in the last well drilled on the old Blue Diamond 20 in section 26. Due east of this work, on the eastern frontier, the Nevada petroleum has a string, of good wells down the center line of 30-20-15, at about 2,400 feet. Adverse water conditions were encoun tered here" and No. 1, which had gen erally 'been counted a lost hole, has finally" been cemented and put on the pump. These wells appear to be doing 200 to 400 barrels each of a medium grade oil. Just on the edge of the town of Coal inga the Valley has a 3,200 foot well which has some oil, but, which up to the present has not been free from water enough to determine its value as a producer. If this well can be finished an area of at least two square miles will be added to known produc tive territory. WILL PROTO JfBW STRETCH; On the much boomed section 6, 20-15 operations are rather at a stand. This territory suffered greatly at the hands of certain operators, who seemed more, anxious to raise the value of their stock than to conserve the value of their property, with the result that haste and careless drilling have -brought about very -serious water troubles. It seems a great pity. that such promising territory should be abused-, and per haps ruined in this offhand manner, but there is reason to hope that if the op erators can be brought to unite on pro tective measures a greater part if- not all of the damage can be undone. Section 6 is surrounded on three sides by lands of the.X. T. & ( O. company, :on which nothing is being done, "and the nearest prospecting- has been on 1 1 1 ! < \u25a0iMitfMi rMili^MWßn MhiMTH ill" h it* 1 Ihi 1 1 m* \u25a0 \u25a0 n 11 » £b£»u«r«: THE SAN 3^RANGISGO^ GAM>, THUHSDAY, APRIL 21y 1910.- Pictures taken in and about Coalinga, showing oil properties, the cozy char attar of the homes and a part of the city. three miles it rolls out straight before the eyes for eight miles. The wonders of park and ocean ar§ not at hand, but on either, side is an unending row, of derricks about . the same., distance apart, so that. the lines of the avenue s perspective extend even" and true to the rolling hills, where they seem to meet. On the leases are newly painted and freshly screened houses each with a little garden and .patch of shade from thriving- trees. | Many of the derricks are boarder! in to prevent the wind from spattering oil over, the buildings. Refuse is s<wept away and there is a pleasing air of neatness and order. FIELD OF DKEP WELLS The wonder of the wells is another story. The oil runs in high gravity, varying from 18 to 30 and beyond. Search the great length of tho fields over and there will scarce be found- a well tiiat is idle or deserted. The leajst that the wells are producing is 206" barrels a day. The majority range between 200 to 1.000 and a few par ticular ones of the gusher class, like the Silver Tip. Mohawk and Blue Moon, are still better. There is an old saying that Coalinga is no place for wildcatting; that" it is strictly a playground for the veterans in the game, and it is more or less true. There are too many reliable companies in the field and the country is too deep. There is scarce a well that enters the oil sand above 2,000 feet, and a great many are between 2,600 and 3.000. . "• The field lies along the edge of a gentle rise in the valley floor, where the plains seom to bend into the foot hills. It scatters along evenly for about 10 miles or more and runs into the undulating arm of a long, low cir cling range of hills sweeping out, over the valley and entirely enveloping the town.- .y EVIDKNCES OF PROSPERITY ' Jn the beginning of things in this field Coalinga boasted of 1,500 inhab itants. At present there are more than 6,000. The town is apart from the 12-21-14, wherein addition to several old holes two or three have been drilled within a short time, but without result. Opinions differ as. -to the reasons for this failure, but it seems to be generally accepted that the formation is too much broken to hold out hope for any profitable production. There is now no work under way on the north side of "Warthan canyon. On the south side of the canyon, on ! 18-21-15, several rigs are at work, and up Jacalitos canyon, but near its mouth, four or five .others, but none of this work has yet reached the conclusive stage. Farther up the 1,600 foot hole of the Jacalitos and the 2,800 foot test of the People's associated, both dry, seem to . stop any extension in this direction, though one rig is still at work on 32-21-15. Out from the mouth of Jacalitos can yon but one rig, the Blair, is at work, but this hole is expected to prove up quite a stretch of country, if success ful. They are now down 2,000 feet. Two pigs are said to be at work on" the Lake side •- of the Kettleman hills. '-The Southfield oil company have two holes at 1,600 "and 1,400 feet ; respectively, on the Kreyenhagen ranch, 33-2-16; this is on the old Black Mountain lease, where a little oil is still in evidence in the old hole. South of this, and consid erably farther out, the . El Cerrite lately quit at 4,100 feet with a dry hole. WORK AT McKITTRICK At McKittrick there is little that is | new. This Held has had the reputation ! of .being spotty, but later work has shown that it is merely very narrow, and further, the producing strip is not altogether straight. The upper or southwest bound of the field was shown years ago, a string of dry holes having been drilled all along this side, and ex tensions .to Ihe southeast seems to be barred by the! deep hole of the>Provi dent on the old Dabney lease, which was dry. .;\u25a0 .„'..•\u25a0 ' ; '.">- \u25a0\u25a0•..;\u25a0 \u25a0••\u25a0:, -v. •..,.

The lease is a scene of the liveliest action. Addi tional facilities for handling production are being installed. North 30 is proving to be a very productive property and one of the greatest wells in the west side district is drilled there, and has been main taining an average daily production of from 1,800 to 2,000 barrels since be ing brought in. . The big pipe line which was recently constructed connecting up with the As sociated line is running the production. A big IS-6-18 pump is being installed at the central station on section 30-20 15, which has a capacity of about 18.000 barrels a day. Forty gas engines have been "ordered for work on different drilling wells. Two have been installed and are in operation with satisfactory results. Recent development on the W. K. and Mohawk property, along with other work In the locality, caused the com pany to begin operations on its section 6, 20-15 property. Five rigs will be i started there in the very, near future. Bunkhouses, 28x100. are, being con structed along with a cookhouse, 72x18, wash house and bath house for the ac commodation "of the men. A 1,500 bar rel water tank has been installed on the hill and three miles of four inch pipe has been laid to supply the opera tions. The drilling will be rushed ahead as fast as possible. Four wells to be completed within the next 10 days are Nos. 5, 6 and 12 on section 19, 20-15 and No. 3 on north 30. All are in the sand and are showing up promlslrigly. INSURANCE MAY ENTER OIL FIELDS Special Agent Makes an Inspec» tion Tour o! Derricks Near Bakersfield There is a possibility that insurance companies will enter the oil fields. Ac cording" to the Oil Journal interest in the oil districts has been manifested by a San Francisco company. One of the greatest dangers in the oil fields is that of fire. There have been many losses in the different re gions in California. Sump holes have caught fire and despite every effort to check them they have burned, some times destroying thousands of dollars* worth of oil. But the greatest loss has not been from the oil storage of from the burning of wells, for that can read ily be controlled by steam.~ The der ricks cost in the neighborhood of $5,000 and the burning of them generally in cludes the engine and belt house. A special agent of a San Francisco company has lately taken a trip through the oil fields near Bakersfleld on a tour of inspection of oil derricks. He has given some stirdy to this class of hazard from the standpoint of in surance, as the insuring of derricks is rather a new departure in underwrit ing. ... The insurance companies have re ceived a good many applications from oilmen who wish to protect them selves from loss by fire, but compara tively few companies are writing them. Seven or eight derricks in the Coal inga. field, have burned during the last 15 months. The principal cause, it Is believed. Is carelessness of the work man about the rig in connection with gas. Two or three of the Coalinga rig 3 were Insured and the company carrying them withdrew from the field and placed derricks on the prohibited list. $c : TWO AGENCIES TO JOIN NEXT MONTH Coalinga and Bakersfield Oper ators Arrange to Pool Their Interests Strong Organization to Protect the Rights of the in dependents The final steps looking to the con solidation of the independent oil pro ducers* agencies of Bakersfield and Coalinga will take place May 4. All preliminary arrangements have been completed and it onJy remains to vote the Coalinga members into the Bakers field body. The way has been paved by enlarging the number of directors in the Bakersfield concern from 55 to 150. All of the contracts of the Coal inga agency will be taken over. This will bring together the prin cipal independent oil producers in the state of California and will give them a greater measure of protection than operators in any oth*r part of the coun try enjoy. The independents ' thus united are able through the producers" •agency to market their product under the most favorablw circumstances. The Independents recently receive*! their checks for the oil marketed under the co-operative agreement. The pe troleum netted a fraction over 4t cents a barrel. It Is generally believed that the price will show an increase before long. The financial statement of the Bakersfield agency is of interest to all Independent operators. It covers the first thjee months of the present year and shows the sale of mor« than $2,000,000 worth of oil during that period.

Former Senator Howard A. Erousrh ton has made an inspection of his Pu rissima hills oil well, which is now over 3.500 feet deep, and has ordered the drillers to continue the hole down aa far as possible. Experts, who have in spected the well, say that the forma tion now encountered is favorable for bringing In a producer. Much interest Is centered in the progress of the com pany as a well brought in on the prop erty would prove a wide area of oil territory.
