Wildcat drilling operations in Montana during 1933 did not yield any discoveries of oil or gas that were of major importance. There was comparatively little drilling in the older proven fields, as most of the interest was centered in the Cut Bank field, where 44 wells were completed. The total number of wells completed in the state during the year was 79, of which 62 were productive of either oil or gas.

The oil and gas industry of New Mexico recorded notable progress ill 1935. More wells were brought in than in any previous year, and important new discoveries were made. The total number of completions was 340, of which 260 were oil wells, 8 were gas wells and 72 were dry holes. The total oil production was 20,228,947 bbl., an appreciable increase over the 1934 production of 16,636,804 barrels. Many of the wells completed in southeastern New Mexico were acidized. This treatment proved highly effective in increasing the capacity of the wells, the resulting potentials usually being two to ten times as large as before acid treatment. In the Lea County fields in which proration was entirely on an acreage basis, the tendency of many of the operators was to complete their wells according to best conservation practice rather than to obtain the largest possible potential. Much remedial work was done in the Hobbs, Cooper, Jal and Eunice fields, and with excellent results. At many of the wells high gas-oil ratios were greatly reduced and encroaching waters shut off by setting packers. Several companies carried on pretentious geophysical campaigns in the southeastern part of the state. The location of the Amerada discovery well in the Monument field was based on geophysical surveys. The New Mexico Oil Conservation Commission, established by the 1935 Legislature and consisting of the Governor, the Commissioner of Public Lands and the State Geologist, began to function in May. Production in the state thereafter was based on orders issued by the Commission. Proration in the Hobbs field, which had been provided for since July, 1930, by successive proration agreements signed by all operators in the field and approved by the State Geologist, was continued by the Commission by giving approval to the current proration agreement,. A plan of proration for the other Lea County fields that had been in offect since early ill 1934 was adopted. 111 September, 1935, the Commission approved a. proration agreement for the Artesia-Jackson-Maljarnar area in Eddy and Lea counties that had been agreed upon by

NO important discoveries of petroleum during 1933 were reported from New Mexico. Lea and Eddy counties were the centers of activity during the drilling season and each had a number of interesting completions. The Hobbs pool, in Lea County, was definitely outlined on the east, north and northwest. Under an agreement reached last summer by state officials and operators, the Hobbs pool was continued under proration throughout the year. One hundred eighty-four units of 40 acres each were being produced at the end of 1933. The allowable was 21,306 bbl. daily at the beginning of 1933, but when the agreement was revised in the spring the minimum was raised to 30,000 bbl., and by the end of the year had been raised to 33,473 bbl. At present the field is being prorated on the basis of 25 per cent on acreage and 75 per cent on potentials except in the southwestern edge of the field, where water encroachment is a problem. In this area the basis of proration is 40 per cent on acreage and 60 per cent on potentials. A corrective method employed in this part of the field has been partly successful. The water is advancing in the upper part of the pay, a dolomitic limestone, and in a number of instances packers have been set in the pay below the water and above the oil. The locating of a satisfactory seat for a packer is difficult and in some instances has not been a complete success. Pipe line runs from the field during the year aggregated 11,413,218 bbl., bringing the total gross production up to 41,093,681 bbl., of which 39,000,-000 bbl. has been produced under proration, which went into effect on July 10, 1930. On Nov. 30, potentials were determined on the assigned pressure basis and the total was reduced 71,165 bbl. daily, to 1,265,-332 barrels. The outstanding completions in the Hobbs pool were three in number, of which the best was the Humble Oil & Refining Company's No. 3B Bowers in sec. 20, 18S., 38E., with an initial production of 11,664 bbl. of oil and 10,000,000 cu. ft. of gas. The Shell Petroleum Company's No. 4B McKinley, in the same section, produced at the rate of 22,940 bbl. of oil while flowing open, but when tubed, flowed at the rate of 6610 bbl.

On the bulk basis New York's contribution to the production of oil is small, representing, as it does, a bare half of one per cent of the annual total for the United States. Yet it has more importance than is implied by such a statement. Petroleum includes a variety of organic compounds, some more and some less valuable. It would be a fairer estimate of the situation to say that New York in recent years has produced around 10 to 12 per cent on the average of all Pennsylvania grade oil, the supply of which is strictly limited and the demand steady even in times of overproduction of other grades. One may not infer from this that New York and other Appalachian states enjoy an independent position in the market with a price structure uninfluenced by that of the Mid-Continent, Gulf or California fields. On the other hand, the recent market demoralization in the South and West brought about by uncontrolled production caused prices to drop to a point where the life of the local industry was seriously threatened. The current cost of producing oil in New York under the methods of water-flooding, by which most of the output is now obtained, has been estimated by competent authority at not less than $2.50 a barrel.

There was more activity in crude production in northwestern Pennsylvania in 1935 than for several years before, resulting in an increased oil production and also in the number of wells completed. Crude -production approximated 16 million barrels for the state, an increase of about one million barrels over 1934. Demand, indicated by refiners' runs to stills, increased proportionally, leaving stocks of available crude at the end of the year at the lowest point since the middle of 1934, when they reached an all-time low. The price of crude varied during the year from a low of $2.02 to a high of $2.27 at the end of the year for Middle district oil. The price of Bradford and southwest Pcnnsylvania oil changed accordingly. The average for the year would be a lower price than in 1934. A summary of the production data for the year 1935 is given in Table 1. In making up this table, 1935 figures were simply added to the table published by S. H. Cathcart last year1. A list of important wildcats is given in Table 2. Bradford Field Approximately 10,000 acres of the proven producing area of the Bradford field is in Cattaraugus County, New York, and it is possible, by differences, to distinguish the Pennsylvania production from the New York portion. The listed production for the Bradford field includes only that portion of the field situated in Pennsylvania, but also includes production from a small pool, locally known as the Mt. Jewett-Kanesholm pool, where the Bradford sand is being developed and flooded in precisply the same manner as that of the Bradford field itself. The Mt. Jewett-Kanesholm pool is not, strictly speaking, an extension of the Bradford field, but inasmuch as it is so closely allied with the Bradford field-—that is, the sand is the same and the production methods are the same—the production and drilling figures include this area.

A summary of oil and gas development in Ohio for 1935 must necessarily be brief. As attention of the state government to the oil and gas industry has never included the collection and compilation of statistics on production, either by producing sands, by counties, by fields, or for the state as a whole, such information as requested in Table 1 of this symposium is impossible to secure for this state. In the absence of production data chief attention must be directed to drilling activity for the year. Information such as can be compiled from various sources, including weekly drilling reports to operating companies and trade journals, is given in the following paragraphs with the realization that the data may not be complete in all its details. Drilling Activity by Fields Drilling activity during 1935 was similar to the preceding year in , that the major operating companies were generally content to drill lease-requirement and offset wells and in that comparatively little effort was made to discover new pools. A compilation of completions recorded in weekly reports to drilling companies and in trade journals show 1022 tests completed for the year in 53 counties of the state. Of this total number, 653 wells were commercial producers and 369 were classed as dry holes. Production was secured in 40 counties from formations ranging in depth to 5700 ft. and ranging in age from Middle Ordovician to upper Pennsyl-vanian. From the standpoint of new production for the year, the most important sands are the Clinton of Silurian age, the Berea of Mississippian age and the Shallow sands of Mississippian above the Berea and of Pennsylvanian age. Trenton Sand Field Production in the field of Trenton sand, which originally included parts of 15 counties in northwestern Ohio, is now on the decline. Seventy-three completions were reported in this field during 1935, of which 33.8 per cent were dry holes. Activity centered in Allen County with 12 completions, two of which were dry holes; in Hardin County with 11 producers; and in Wyandot County with 12 producers and 2 dry holes.

Improving economic conditions are reflected in the statistical picture of the petroleum and natural gas industry for 1933. Prices were better, demand was greater and the volume of production increased. The increase in the production of gas has been due mainly to the utilization of outlets to the new prolific gas fields of Potter and Tioga counties; of oil, to the growing demand for Pennsylvania grade lubricants. It should be emphasized that nowhere is volume of production more subject to control due to the extensive use of secondary methods of recovery and regional peculiarities than in Pennsylvania. A summary of developments in production for Pennsylvania in 1933 of necessity is brief. The data listed in Table 1 are all too few in number and not all that is desirable from the standpoint of accuracy. No state agency for the collection of data exists, no reports are compulsory. Nevertheless, because of the hearty cooperation of many individuals and public spirited corporations, it is believed that the data are as reliable as are obtainable at the present time. Furthermore, records of the past too often are lost, were never in existence or are fragmentary, to say the least. Illustrative of the condition is the fact that no thorough study of the oil and gas-producing regions has ever been made. The publications of the Pennsylvania Topographic and Geologic Survey upon the subject are noteworthy and valuable, especially the most recent one.' The Survey has been handicapped in the work by lack of time, personnel and funds in addition to the difficulties mentioned previously. It is obvious, therefore, that Table 1 cannot be completed for Pennsylvania. The data simply are not in existence. Officially there are 328 oil and gas pools or fields known by name and 58 distinct sands or horizons, one or more of which are productive of oil and gas in the various pools, but reliable data for only three general regions could be assembled.

There were no important developments in the oil and gas industry in South Arkansas during 1935. Oil production, totaling 11,138,340 bbl., continued the decline that has been normal since 1925, but the decline from 1934 was only 278,600 bbl., or 2.5 per cent. The principal decline was in the Smackover field, while only the Champagnolle and Garland City fields showed notable increases. More wells were drilled than in any recent year, with a total of 123 completions. There were 44 oil wells, with a total reported initial daily production of 10,013 bbl., or an average of 227 bbl. per well. Two small gas wells were completed in Union County, where the gas is used locally for pumping and field operations. There were 77 dry holes, of which 28 were in or near oil fields and 49 were wildcats. Active drilling oper-at'ions declined from 65 at the beginning of 1935 to 41 at the end. Most of the drilling was done during the first part of the year, espr-chially (luring the flurry caused by the discovery late in 1934 of the "Taylor" sand production in the Champagnolle field, but the producing area was soon outlined. In November, 1935, the J. E. Crosbie, Inc., NO. 1 Sullivant in sec. 12, 17s. 14W., producing 560 bbl. per day at 3175 ft., opened a new sand lens in the eastern part of the field. The Camden "oil field," discovered in the last week of 1934, remained a one-well field, although four offset tests were drilled, besides a number of others in the immediate vicinity. Several interesting deep tests were drilled during the year, which added a great deal to the general knowledge of the subsurface formations and the structure of south Arkansas, but were not particularly encouraging as to prospects for the very deep production. First, the H. L. Hunt, No. 15 E. F. Gregory well in sec. 10, 17S., 14\W., in the Champagnolle field, was drilled to a depth of 6911 ft. It pene-trated red beds for 2982 ft., from 2943 to 5925 ft., mostly if riot entirely of Lower Cretaceous age. There was some anhydrite in the last 135 ft. of red beds. This was followed by 890 ft. of limestone, probahly Permian, and the rock salt was struck at 6815 ft. The salt is now generally conceded to be of Permian age.

At the beginning of the year 1935 the older fields in Southwest Texas, and particularly those discovered during 1934, had been practically delimited and only normal development continued. As a result, operations in this area were somewhat slowed down. Shortly after the first of the year, however, activity in the area was greatly accelerated, due largely to the fact that the Loma Novio field, discovered during the last few days of 1934, indicated the presence of a new productive trend east of and parallel to the Government Wells field and also indicated the presence of a new productive horizon, the Loma Novio sand, approximately 100 ft. lower than the Government Wells sand zone. Other discoveries during the year greatly augmented the activity in the district. During the year there were 651 oil wells, 53 gas wells and 275 dry holes drilled in this area during the year. Most of the operations were in the Government Wells, Cole, Loma Novio, Seven Sisters and Lopez fields. New Fields Four new fields were discovered during 1935 as follows: Seven Sisters and Piedra de Lumbre in Duval County; Loma Alto in McMullen County; and Lopez in Webb County. Seven Sisters Field.—The Seven Sisters field, opened in May, was the direct result of a systematic search for new productive areas northeast of the Loma Novio field. The first producer, Harvey & Henderson NO. 1 Chernosky, survey 226, was completed in the Labbe (Chernosky) sand at 2220 ft. However, the second producer, Santa Clara Oil Co. No. 1 Welder in survey 385, drilled about one mile south of the discovery well, failed to find production in the Labbé sand and was carried on down and completed in the Government Wells sand at 2473 ft. with an initial production of 20 bbl. of oil per hour. These two discoveries, in the Labbé and Government Wells sand, started an active leasing and drilling campaign in this part of Duval County and drilling operations continued especially active throughout the remainder of the year.

Production of crude oil in Tennessee during 1935 approximated 20,000 bbl., an increase of about 5000 bbl. over 1934. The total production for the state is an estimate, since the only definite figures available are those for Scott and Morgan counties, where 12,377 bbl. were marketed during 1935, an increase of 4305 bbl. over the preceding year. The oil fields of Scott and Morgan counties are near the eastern margin of the Cumberland Plateau where Pennsylvanian sediments rest uncon-formably upon the Mississippian. Near Glenmary, in Scott County, the production is from the middle Mississippian, probably near the top of the St. Louis limestone. Accumulation is due to a low, east-west anticline which has been cut by a fault. This field is now 20 years old and only a few wells are pumped at present. Oil was Struck along Boone Camp Creek in Morgan County in 1924 and there has been small production since that time. The oil comes from the middle of the Fort Payne formation of lower Mississippian age at a depth of 1400 ft. Geologic work in the area has shown that a terrace and porosity conditions in the Fort Payne formation account for the accumulation. The production figures on a number of small producing wells in Clay and Overton counties are not available. As pointed out by Glenn1, the installation of small local skimming or topping plants in the fields has curtailed the shipment of crude oil out of the state and as a result it has been impossible to secure accurate production figures in these counties. The operators, in most cases, are reluctant to give information, and there is no state law requiring them to do so. Based upon information available to the writers, it is believed that between 7000 and 8000 bbl. is a fair estimate of the production in Clay and Overton counties during 1935. More than 500 wells have been drilled in Clay County, the majority of which were drilled east of Cumberland River. Some eight small oil fields have been developed in the county within the past 12 years, a

During the year, there were 570 oil wells completed for a total daily initial production of 365,352 bbl. The daily oil potential of the field, effective Jan. 1, 1935, as established by the Texas Railroad Commission, was 306,102 bbl. with a daily allowable of 58,800 bbl., whereas, on Dec. 31, 1935, the potential was 587,376 bbl. with a daily allowable of 57,800 bbl. Because of the limited market demand, the allowable decreased although the potential increased. In August, the five-day test for determining the potential production of a well was replaced by a 24-hr. test. The reason for this change was that some of the oil-pur-chasing companies contended that too much oil in excess of the limited market demand was produced during the five-day tests. Dry Gas.—During July, the Texas Railroad Commission supervised the first complete and accurate field-wide test of open flows that has been made in this area. The total open flow as determined at that time was 16,426,085,000 cu. ft, There were 79 gas wells drilled in '935, with a combined open flow of 2,408,000,000 cu. ft. and 50 depleted oil wells were plugged back for gas with a total open flow of 529,800,000 cu. ft. The total new gas production for the year was, therefore, 2,937,800,000 cu. ft. The 17 natural-gas pipe lines drawing on the Panhandle supply of fuel gas withdrew a daily average of 420,497,507 cu. ft., or a total of 153,481,-590,000 cu. ft. for the year. The 44th Texas Legislature passed a statute known as House Bill No. 266, which was designed to prohibit waste and protect correlative rights by compelling the ratable production of gas. The part of the law relative to withdrawal of sweet gas became effective Aug. 1, 1935, and the part referring to withdrawal of sour gas became effective Oct. 1, 1935. Three of the major pipe line companies attacked the validity of the ratable production feature of the new law and a preliminary injunction was granted by the Federal District Court. The final hearing on the incrits of the case is scheduled for the early part of January.

During the year, there were 570 oil wells completed for a total daily initial production of 365,352 bbl. The daily oil potential of the field, effective Jan. 1, 1935, as established by the Texas Railroad Commission, was 306,102 bbl. with a daily allowable of 58,800 bbl., whereas, on Dec. 31, 1935, the potential was 587,376 bbl. with a daily allowable of 57,800 bbl. Because of the limited market demand, the allowable decreased although the potential increased. In August, the five-day test for determining the potential production of a well was replaced by a 24-hr. test. The reason for this change was that some of the oil-pur-chasing companies contended that too much oil in excess of the limited market demand was produced during the five-day tests. Dry Gas.—During July, the Texas Railroad Commission supervised the first complete and accurate field-wide test of open flows that has been made in this area. The total open flow as determined at that time was 16,426,085,000 cu. ft, There were 79 gas wells drilled in '935, with a combined open flow of 2,408,000,000 cu. ft. and 50 depleted oil wells were plugged back for gas with a total open flow of 529,800,000 cu. ft. The total new gas production for the year was, therefore, 2,937,800,000 cu. ft. The 17 natural-gas pipe lines drawing on the Panhandle supply of fuel gas withdrew a daily average of 420,497,507 cu. ft., or a total of 153,481,-590,000 cu. ft. for the year.

Development work in the state of Utah in 1935 consisted of additional work done on wildcat tests started in previous years and on a number of new wildcat tests started during the year. No effort was made to extend areas or to discover deeper productive horizons in proven fields. Principal areas of development were in Daggett County, northeastern Utah; Grand and Emery counties, east-central Utah; and in Washington County, southwestern Utah. Daggett County Clay Basin.—The Mountain Fuel Supply Co. deepened Murphy No. 2, sec. 21, T.3N., R.24E., from 6030 to 6790 ft. for a test of the Sundance formation. Two sandstone members at 6520 to 6644 ft. and 6737 to 6790 ft. contained water. The hole was plugged back to 5860 ft. and left as a future gas supply for the Salt Lake City-Ogden pipe line. The failure of the Sundance formation to produce in this test, in view of the recent Sundance discoveries in Colorado arid Wyoming, was disappointing Emery County Last Chance.—-Thc wildcat test of the Rainsey Petroleum Corporn-tion, Well No. 1-X, sec. 18, T.26S., R.7E., completed plugging back from total depth of 3168 ft. to 2771 ft. and was shut in as a gas well. A gas sand at 2724 to 2771 ft. produced approximately 21 million cubic fert. A deep test of the structure will be started upon approval of a wit plan of development. Grand County Cisco.—-The wildcat test of the Utah Southern Oil Co., sec. 33, T.22S., R.22E., of which the total depth was 1720 ft. on Dec. 31, 1935, is the most interesting operation ill the state.
