The world's production of petroleum in 1926 amounted to nearly 150 million long tons, of which India contributed 0.72 per cent. In 1927, this figure jumped to some 172 million long tons, of which the Indian proportion, on a practically stationary production, fell to 0.64 per cent. In 1928, there was another substantial rise in the world's production, which reached the figure of over 181 million tons. In 1929, there was another jump to over 202 million tons, but in 1930 the world's production fell to about 193% million tons, in 1931 to about 187 million tons, and in 1932 to about 183 million tons, while in 1933 the production rose again to about 202 million tons, in 1934 to about 215 million tons, and in 1935 to 233 million tons1. Decreases were shown by Poland, Sarawak, Egypt, Rumania and France. All other important producers showed an increase in production, by far the largest being due to Iraq, as a result of the opening of the pipe line to the Mediterranean. The United States contributed 60.9 per cent of the world's supply in 1935, Russia 10.7 per cent, Venezuela 9.4 per cent, Rumania 3.9 per cent and Iran 3.1 per cent. In 1928, India contributed 0.64 per cent, which fell to 0.60 per cent in 1929 and rose to 0.62 per cent in 1930, 0.63 per cent in 1931, and 0.64 per cent in 1932, and fell again to 0.62 per cent in 1933, to 0.60 per cent in 1934 and to 0.50 per cent in 1935; her position on the list of petroleum-producing countries fell from eleventh in 1929 to twelfth in 1930 to 1933, her place being taken by Trinidad and to thirteenth in 1934 and 1935, owing to the production by Iraq. The production of petroleum in India (including Burma2) increased slightly from 322,025,280 gal.3 in 1934 to 322,662,336 gal. in 1935, the highest figure in the history of the industry. The increase in 1935 is due to an increase of some 4 million gallons in Assam, almost offset by a decrease of 31/2 million gallons in Burma. This increase in output in 1935 was accompanied by an increase in estimated value amounting to Rs. 22,73,550 (£170,944).

The production of petroleum in Venezuela during 1931 was approximately 118,767,000 bbl., a decrease of 18,904,000 bbl., or 13.7 per cent, compared with the previous year. This is the first break in production, which has risen steadily since 1920, and is attributable to restriction of output and drilling operations, in harmony with lessened demand, rather than to any real decline in potential production. Venezuela ranked third among the world's producers, having lost second place to Russia. The Bolivar coastal fields, which were extended approximately 14 miles southward during the year, continued to supply most of the oil. La Concepcion, Los Manueles and Quiriquire all showed marked increases. A new field of light oil was discovered on the north coast near Puerto Cumarebo, State of Falcon. Exports declined 15.7 per cent, from 137,377,000 bbl. in 1930 to about 115,800,000 bbl. in 1931. Crude oil in storage at the end of the year amounted to 7,450,000 bbl., a decrease of 2,150,000 as compared with 1930. Tankage utilized is about 40 per cent of the available space. A drastic decline in drilling activity reduced the number of wells completed in producing areas from 401 in 1930 to 116 in 1931. Only three wells were drilled in the Lagunillas field proper, but, the amount of closed-in production and proven acreage gave assurance of a satisfactory potential output. Of the 1580 wells drilled to the close of 1931 in the producing areas of the Bolivar Coast, 631 were active and 853 were closed in; 96 had been abandoned. The status of the active wells at the end of 1931 was as follows: flowing, 331; pumping, 99; gas-air lift, 201. Producing wells closed in numbered 452; workovers, 8; totally inactive, 393. Lago Petroleum Corp. and Venezuela Gulf Oil Co. placed in operation the first units of their electric power plants, the former at Punta Gorda and the latter at Las Morochas, and are replacing steam power in their operations as rapidly as possible. Compressor stations were also installed for use in connection with air-gas lift operations. A considerable volume of gas was treated in gasoline extraction plants, the tail gas being recom-pressed and utilized together with natural high-pressure gas, for stimulation of production.

Drilling operations in Nebraska during 1943 were reduced to approximately two thirds of the 1942 number. Twenty-seven wells were completed during 1943 and five wells were drilling at the close of the year. Eight of the completions, in provcn fields, were producers. The operations were distributed throughout the state as follows: eleven in Richardson County, four each in Buffalo and Harlan Counties, three in Furnas County, and single operations in Antelope, Butler, Dakota, Dawes, Gage, Nemaha, Otoe, Pawnee, Scotts Bluff and Sherman Counties.

The total pipe-line runs of petroleum in Indiana during 1945 were 4,114,000 bbl., a decline of nearly 17 per cent below the estimated 4,950,000 bbl. produced in 1944. Drilling activity during the year was centered in Posey and Gibson Counties, where seven new pools were discovered in the state. Four of the pools are in Posey County-Crunk, Farmersville, Jeffries and St. Wendells East-and the other three are in Gibson County-Johnson West, Lysle and Mt. Carmel East.

Drilling activity in Nebraska continued to decline during 1944. Nine tests for oil and gas were completed during the year and four wells were drilling at the close of the year. Four wells were drilled in Richardson County, three in Hitchcock County and single wells were drilled or drilling in Butler, Gage, Holt, Nemaha and Scottsbluff Counties. Only one of the completions resulted in commercial pro- duction, the others being abandoned as dry holes. A number of stratigraphic test holes were drilled in the state by the Stanolind Oil and Gas Co. and the Sinclair-Prairie Oil Co., in Johnson, Otoe, Chase, Dundy and Garden Counties. No new fields were discovered during 1944 but the limits of the Barada field, Richardson County, was extended a short distance southward. Oil production continued to drop and about two thirds as much oil was produced in 1944 as in 1943.

METHODS and equipment are subject to study in the Butte district at all times in order that advantage may be taken of any new developments that might serve to increase efficiency and lower costs. Detailed time studies of each operation involved in the entire mining process have been of invaluable assistance in analyzing the individual operation for possible improvement. In other words, the fact that a practice has been in vogue for many years does not exempt it from change provided an easier and cheaper method can be found. EXPLORATION Ore occurs in the Butte district in such manner that structures must be drifted on, no matter how small or unimportant they appear when intersected by a crosscut. Parallel structures also add to the crosscut requirements. This prospecting work, which formerly was done entirely by drifting and crosscutting, is now being supplemented by diamond drilling, to aid in greatly decreasing the amount of waste. In long-shot prospecting, or in second or third class prospecting, where the chances of developing commercial ore are not very great, diamond drilling is of particular value. In prospecting where chances of encountering commercial ore are certain or where crosscuts can be used later for haulage or ventilation, drilling obviously is not applicable. Improvement in drilling machines and bits has contributed greatly to the present success of diamond drilling. STOPING For many years square-set filled sloping was the principal mining method used in the Butte district. Later timbered and untimbered rill stopes were used, also some horizontal cut-and-fill sloping where both ore and walls were particularly strong. Because of the amount of timber required for square-set stoping, and the relatively low production per scope unit, experiments with horizontal cut-and-fill scopes were begun in ore bodies of which many had fairly weak walls. It was felt that increase in the speed of the stoping operation, followed closely by filling, to avoid weight being produced by permitting ore and walls to remain insufficiently supported over comparatively long periods, would maintain the walls and backs in safe condition without the use of timber and without ore dilution from wall slough. Cycles of drilling, scraping ore, and filling were devised, which have materially increased stope production and decreased timber consumption, so that both stope labor and supply costs were lowered appreciably without materially affecting grade control. In the larger mines of the district, where wide veins favor this stoping method, half of the total production is now being mined by horizontal cut-and-fill stopes (Fig. I). The increase of the filling rate demanded by the increased stoping rate was the greatest obstacle encountered in the accelerated stoping operations. Finally this problem was solved by replacing the time-honored method of transferring filling waste by small cars, which were hoisted or lowered in the auxiliary shaft, by a transfer

Ninety wells were completed in Nebraska during 1941, of which 42 were producers. One of them was the discovery well of a new field. All of the production to date is in Richardson County. At the close of the year 14 wells were drilling and three more were shut down for orders, hoping for future development of production. Most of the drilling activity was in Richardson County, which had 68 operations; 10 wells were drilled in Nemaha County, 5 drilled or drilling in Gage County, 3 each in Otoe and Furnas Counties, 2 each in Cass, Harlan, Johnson and Sarpy Counties, and 10 wells were completed or drilling over the remainder of the state. The most important development of the year was the discovery in October of the Barada field, sec. 36, T. 3 N., R. 16 E.,

The value of the earth resistivity method in groundwater studies in Illinois has long been recognized. Owing to the sharp electrical contrasts between sand and gravel deposits and glacial till, alluvial silt or underlying shale, much of the earth resistivity prospecting has been of a relatively elementary nature and has been highly successful. Approximately 90 pct of earth resistivity interpretations by the State Geological Survey have been accurate for practical purposes. Four studies involving fairly simple geologic situations are presented in this paper as typical cases. FOR the past 20 years electrical earth resistivity exploration has been used in Illinois in many phases of study undertaken by the State Geological Survey, chiefly in locating and outlining deposits of water-bearing sand and gravel from which to obtain ground water for municipal and industrial supplies. At least 43 municipalities in the state derive their total water supply from deposits of sand and gravel discovered by resistivity methods. These deposits occur in both Quaternary and preglacial valleys and within much of the glacial drift which covers a large portion of the state. In recent years there has been much demand from rapidly growing municipalities for help from the Illinois Geological Survey to extend existing well fields. Water supplies for many and varied industries constitute a considerable portion of the Survey's studies. The diminishing need of water supplies for railroads has 'been accompanied by an increasing demand by the oil industry for water for secondary recovery programs. The instruments used by the Illinois Geological Survey follow closely the commutated direct current circuits developed by O. H. Gish and W. J. Rooney' using the Wenner2 electrode configuration. More recently replacement of the hand-driven commutator by a synchronous vibrator has led to increased ease of operation and accuracy. Continuing improvement of equipment and technique has led to many changes in the instruments, but the operating theory remains the same. In the field operation at a selected station, four electrodes are set at equal distances in the ground 6 to 10 in. deep, in a straight line. A 16 to 20-cycle current is applied to the two outside steel electrodes

Production of petroleum and natural gas increased in Canada in 1939 principally because of new wells in Ontario and Alberta. Turner Valley The Turner Valley field, Alberta, yielded 7,456,000 bbl. of petroleum in 1939 in comparison with 6,703,548 bbl. in 1938, an increase of 11 per cent. Turner Valley now supplies 96 per cent of all petroleum produced in Canada (Table 1). The Turner Valley field (Table 2) has reached a position where it call supply much larger volumes of petroleum than the Prairie market is capable of consuming. The allowable production is under the jurisdiction of the Petroleum and Natural Gas Conservation Board of Alberta and the daily rate is set from time to time as warranted by the demand. During June the allowable reached a maximum of 27,000 bbl. a day. This, however, was a temporary situation due in part to the completion of a new British American Oil Co. refinery in Calgary capable of processing 5000 bbl. a day and with a storage capacity of about 100,000 bbl. The maximum consumption was reached during the harvest season with

During no similar period in the development of petroleum refining technology has so much progress been made in methods and equipment for the economical utilization of heat. Drastically severe commercial and economical conditions controlling the refining industry during 1927 gave a great impetus to improved efficiency and more economical operation in all departments. I think it is fair to say, however, that more progress has been made in the department of heat utilization than in other branches. I use the word utilization advisedly in the dual sense of better primary generation and application of heat and of saving by recovery methods. It was because of this trend that the subject, "Economical Application of Heat," was made the keynote of the refinery engineering sessions just completed. No new, outstanding elemental discoveries can be claimed for the year along this line. Some of the progress made has been in the development of better furnaces and distilling equipment embodying the more modern principles of boiler practice in obtaining complete combustion of the fuel, low excess air requirements and high transfer rates through the heating surface. Transfer rates of 3000 to 6000 B. t. u. per sq. ft. per hr. were considered good some time ago in the older type of equipment. Today a transfer rate of 25,000 to 35,000 B. t. u. is an actual accomplishment in commercial installations and engineers are talking of the feasibility of 50,000, 75,000, even 100,000 R. t. u. per sq. ft. per hr. Contributing most to bringing this about have been the rational use of the velocity factor on both the oil and firing side of the heating surface, and the study and application of the principles of radiant heat in furnace design. Vapor Heat Economy The principle of heat exchange, especially against oil vapors, has been applied to a greater extent than ever before. The recovery of heat from oil vapors is not new. This was practiced 20 years ago or more in Europe,

The general curtailment of activities, so marked in 1931, was continued and intensified in 1932 and although production was maintained at approximately the level of the previous year, 1932 was chiefly characterized by the virtual cessation of drilling in many of the proven fields, a further decline in wildcatting activities, particularly in the Maracaibo Basin, and the relinquishment of large blocks of unfavorably located acreage. A total of only 60 wells was completed during the year of which six were wildcats, while at the same time concessions aggregating approximately. 3,222,000 acres were renounced and reverted to the National Government. The maintenance of production at the previously established level was made possible through the large potential built up by drilling in previous years and by a gradual increase in pumping and gas-lift installations. Towards the end of the year there was a slight but perceptible tendency towards increased drilling in certain of the proven fields. Total production for the year came to 118,076,000 as compared to 118,418,000 bbl. for 1931, while exports amounted to 114,758,000 as against 116,683,000 bbl. in 1931. Table 1 shows production and exports and the average rate per day for the first half of 1932 as compared to the second half.

THE Workmen's Compensation Act of Ontario was passed in 1915 and Miners' Phthisis was added to the list of compensable industrial diseases in 1916. Under this provision of the Act only about two cases were compensated per year. In 1924, The Department of Public Health made a survey of miners in the four principal camps-Sudbury, Porcupine, Kirkland Lake and Cobalt-and the survey indicated that an alarming proportion of the men exposed to dust had silicosis in one or other of its several stages. A number of conferences were held between representatives of the Department of Mines, the Department of Public Health, the Compensa-tion Board and the mine operators. The operators were advised that in the earliest stages of silicosis there was no physical disability and if men in that stage were removed froni underground there would be little danger of permanent disability. They were further advised that if active steps were taken at once to compensate men that had some real disability and remove from the mines men in the early stages of silicosis, the first cost would be the greatest and thereafter their liability should decrease. As a result of this advice, and having at that time no reason to doubt the findings of the survey, the operators agreed to do all that was asked of them and cooperate with the Government in the steps believed neces-sary to meet the situation, and to provide compensation for the men affected.

TuRneR Valley, on the eastern edge of the foothills of Alberta, 35 miles southwest of Calgary, continues to be the major oil field in Canada. This field began production of gas and naphtha from the Mississipian (Madison) limestone in 1924, and until 1936 all wells were drilled for these products. At the end of 1938 there were 104 gas wells. In 1936 proof was found of a crude oil zone in the same horizon but lower on the west flank of the structure, which is a large fold cut off on the east side by an overthrust fault of great displacement. Since 1936 drilling has been done for the development of crude oil and at the end of 1938 there were 64 crude oil wells. On test through a 1-in. choke these flowed at the rate of 50,000 to 60,000 bbl. a day, but on production would not be expected to make this volume. The output has been prorated according to the capacity of the Prairie market. During the harvest season, when the demand for oil and oil products was at its maximum, the allowable production of Turner Valley was 28,363 bbl. per day. With the arrival of winter, this was cut to 11,500 bbl. per day but later was raised to 12,500 bbl. Production in 1937 from Turner Valley was 2,767,221 bbl., which was more than double that of the previous year. Production in 1938 was 6,691,075 bbl., which is considerably more than double that of 1937.
