Petroleum is produced in Canada in the provinces of New Brunswick, Ontario and Alberta and in the Northwest Territories. The total production, however, is relatively small in comparison with the consumption, the value of imports exceeding 40 million dollars a year. Production figures are given in Tables 1 and 2. In Turner Valley, still the largest producing gas and oil field in Canada, five wells were completed during the year. The largest of these

There have been no major field developments during 1935. Operations have proceeded normally on the company's three producing fields, Masjid-i-Sulaiman, Haft Kel and Naft-i-Shah. The refinery at Kermanshah was commissioned in September, 1935, with a rated throughput capacity of 75,000 tons a year of topped crude to meet local requirements. Crude production from the Masjid-i-Sulaiman and Haft Kel fields is tabulated below: Masjid-i-Sulaiman Field.—The flowing lives of wells have been extended by (I) a process of acid treatment, thereby reducing the bottom-hole pressure differentials, and (2) by reducing the back-pressure. Optimum producing conditions for individual wells have been determined as a result of an experimental study of the amount of available energy in the reservoir crude and of energy losses in flowing wells. The return of surplus products to the reservoir has continued to be a satisfactory economic operation and the crude throughput capacity of the topping plant has been increased. The viscosity of residue returned to the reservoir is reduced before injection by regassing at 35 lb. per sq. in. absorption pressure with surplus gas. The pressure in the gas dome is falling at the low rate of one pound per annum. Haft Kel Field.—The delimitation of the main structure has proceeded; the oil-bearing area so far proved being about 50 square miles.

The principal events during the year consisted in the exploitation of the Kirkuk field, the regular operation of the four-million-ton pipe line to the Mediterranean, and the discovery of low-gravity oil on three other structures in the West Tigris (Shergat) area. The Iraq Petroleum Co., Ltd. continued the systematic exploitation and exploration of its Kirkuk field, maintaining a carefully unitized operation. Bottom-hole pressure differentials and low gas-oil ratios were maintained. All crude was produced by flowing The cleaning up following the construction of the Mediterranean pipe line, which began deliveries in August, 1934, was completed during the first quarter of 1935. The line easily maintained its rated capacity for the remainder of the year. The Mosul Oilfields, Ltd., through its operating subsidiary, the B.O.D., Ltd., expanded its exploratory organization from 9 to 16 drilling rigs and discovercd 20" A.P.I. crude on the Sadid, Hibbarah and Qasab anticlines. Whether these discoveries will be commercial pools remains to be proved. The Qaiyarah-Najmah-Jawan field, which was discovered by the I.P.C. in 1928, was extended arid production was found in the Eo-Cretaceous as well as the "Main Limestone" (Eocene, Oligocene and Lower Miocene). Gas caps were found under each of the crests of the West Tigris structures. Negotiations are in progress between the Mosul Oilfields, Ltd. and the Iraq Government for the extension of the Anatolian Railway from the Turkish border to Mosul, with a view to tanking the heavy West Tigris crude to the Mediterranean. The subsidiary of the Anglo-Iranian Oil Co., Ltd.', the Khanaqin Oil Co., Ltd., continued to operate its Naft Khaneh field near the Iranian (Persian) border to supply the local Iraq market through the Rafidain Oil Co., Ltd. Somewhat more than 28 million barrels of crude was produced in Iraq during 1935. Crude delivcred to the pipe line for export during the years 1934 and 1935 was: Year BaRrels 1934................................................. 7,096,669 1935................................................. 27,014,904 Total as at Dec. 31, 193.5.............................. 34,111,573 ° Converted at an avcrage of 7.0 bbl. per ton.

Oil has been produced in Persia and India for many years, but it was not until 1932 that Arabia entered the arena as a potential oil-producing area. In 1930 the Standard Oil Co. of California acquired a concession covering the rights of exploration and exploitation for oil in the Bahrein Islands and in June, 1932, the first commercial production was discovered by the bringing in of a well known as Jebel Dukhan No. 1 on the Island of Bahrein. Since then the Standard Oil Co. of California through its wholly owned subsidiary, The Bahrein Petroleum Co. Ltd., has been carrying on a systematic survey and development program of its concession in the Bahrein Islands. This group of islands, of which Bahrein is the largest, is in the southwestern portion of the Persian Gulf, approximately 25 miles from the mainland of Arabia. Although geographically a part of Arabia, the islands are not a part of the Kingdom of Saudi Arabia. Their government is essentially independent but certain special rights have been granted to Great Britain through a series of treaties. The Island of Bahrein is 32 miles long by 9 1/2 miles wide and covers an area of 215 square miles. Approximately three-fourths of the island is occupied by a relatively low, broad, elliptically shaped dissected hill, the central part of which is slightly depressed with inward-facing cliffs but culminating in the Jebel Dukhan (Hill of Smoke), which rises to an elevation of 443 ft. above sea level. The topography of the island is a good index of its geologic structure. Structurally the island is an elongated dome or quaquaversal fold composed of rocks of Eocene age. The major axis of the fold strikes N.5W. All of the topographic high portion of the island is a part of the structural uplift. The crest of the fold is broad and flat with the dips increasing on the flanks. How far tilted strata may continue beyond the line where the Eocene beds are covered by recent sands and detrital material is not known. Superimposed on the general structure are a few small irregularities in the form of minor folding and faulting. There is, however, no evidence of any major faults. The largest of the irregularities lies to the south of Jebel Dukhan and has the appearance of a sink

The work of The Bahrein Petroleum Company, Ltd., on Bahrein Island consisted mainly in continuing development work and prospecting previously reported. The exploratory work, however, has been greatly minimized and new wells are being drilled, chiefly for the development of larger production; 20 wells had been completed by the end of 1935 and 8 were being drilled. In addition to what has been referred to as the ''main pay," two deeper productive horizons have been discovered, which apparently will greatly increase the potential of the field although the areal extent of this lower production has not yet been determined. The proven acreage of the "main pay" is more than 12,500 acres. Current production (principally from the upper horizons) is about 13,400 bbl. a day. The construction of a 10,000-bb1.-a-day refinery has begun and is to be in operation by July, 1936. It is expected that the capacity will be considerably increased at a later date. The construction of office buildings and a permanent camp has been almost completed. In Saudi Arabia the California Arabian Standard Oil Co., a wholly owned subsidiary of the Standard Oil Company of California, spudded in a well in April, 1935, near the village of Dammam, on the Persian Gulf coast of A1 Hasa. Although several important showings of high-gravity oil and considerable gas have been found, the well is not yet considcred a commercial producer. Dammam well No. 2 has been started farther south on the same structure. A great deal of reconnaissance and some detailed geological work has been completed during the last three field seasons. In order to overcome difficulties of transportation over the desert sand, unusual methods have been used. The parlies penctrating the interior by the use of automobiles and trucks have been supplied with gasoline and provisions by caravans of camels. Mail and supp1ies of lighter weight urgently needed have been carried to the field men by an airplane operated by the geological division of the company. Each party has been supplied with a radio receiving and transmitting set to keep in contact with the airplane as well as with geological headquarters at Jubail on the coast of A1 Hasa.

There was no development work in Bolivia during the year 1935, and oil was produced only to meet the needs of the army and of the local market. The refineries in the districts of Camiri and Sanandita treated 25,978,737 liters (163,388 bbl.) of crude oil, which yielded 4058 bbl. of aviation gasoline (Camiri only), 7381 bbl. of gasoline, 718 bbl. of kerosene (Camiri only) and 83,105 bbl. of fuel oil.

The production of oil in Colombia during 1933 was at the lowest level since the completion of the loop of the Andian pipe line in 1927. The commercial production amounted to 13,157,641 bbl., all of which was produced from the Infantas and La Cira structures of the Tropical Oil Company. One of the most important developments was the discovery of what may be commercial production on the Colombian Petroleum (Gulf) Company's Tarra anticline on the Barco Concession in eastern Colombia near the Venezuelan border. This promises to become the second commercially productive area developed in Colombia and, perhaps, one of major importance. Applications made in 1931 for concessions under the new Colombian petroleum law were ratified covering the Putana application of the Tropical Oil Co. and others of local Colombian and French interests west of the Carare River. On none of these concessions has any development work yet been initiated. South American Gulf Oil Company The following information covering the activities of the South American Gulf Oil Co. was furnished by E. S. Bleecker, chief geologist of the company. Magdalena Valley.—No development work was undertaken during the year either on the Valenzuela property acquired from the Colombian Syndicate or on the lands obtained from the Leonard Oil Development Co. near the Sogamoso River. The Valenzuela property was relinquished and a portion of the material was removed therefrom to the Leonard property near by. Colombian Petroleum Co.—The Colombian Petroleum Co., controlled by the Gulf interests, pursued an active development campaign on the Chaux-Folsom or so-called Barco Concession in the Department of North Santander. The drilling of the first well was begun early in the year on the north Petrolea dome of the Tarra anticline and at 490 ft. a heavy flow of oil, gas and salt water was encountered. On blowing in unexpectedly, the well caught fire, and after being extinguished was controlled only by pumping large quantities of cement into the formation and plugging the well. The drilling of the second test, No. 1-A, approximately one kilo-

In past years the exploration of the oil possibilities of Colombia has been confined to parts of three distinct physiographic provinces; namely, the coastal plains area near the Caribbean Sea, the Magdalena Valley and the upper reaches of the Maracaibo Basin near the Venezuelan border. During 1935, little exploratory work and no drilling was carried on on the coast, but there was considerable activity in the other two areas. In the Magdalena Valley, the Tropical Oil Co. continued its producing and development operations on the De Mares Concession. The Socony-Vacuum exercised the option it acquired in 1934 on Sr. Luciano Restrepo's concession adjacent to the Tropical property and north of the Sogamoso River. No wells have been started on the Socony's lands although, according to the terms of the lease, drilling must be started within the next two years. West of the Carare River and adjacent to the Tropical's southwestern boundary, the Sociedad Nacional del Carare denounced the lands formerly held by the Union Colombiana, whose lease automatically lapsed during the year owing to the company's failure to comply with its drilling obligations. In the same area, the concessions held by Callejas et al. and the Société Européene des Pétroles are also understood to have lapsed for the same reason. Holdings of other interests in the Magdalena Valley were inactive during the year. Near the upper part of the Maracaibo Basin, the Gulf, through its subsidiary the Colombian Petroleum Co., continued active exploration and development on its Barco concession. Colombian Petroleum Co.—The following information and that presented in the accompanying tables relating to the activities of the Colombian Petroleum Co. was supplied through the courtesy of Mr. E. S. Bleecker, chief geologist of that company. Four wells were completed during the year on the north Petrolea dome, where an attempt is being made to define the limits of the field. On the south end of the Petrolea anticline, one well, Petrolea No. 3, which might be classed as a wildcat, encountered a heavy flow of salt water immediately below the oil zone and had to be abandoned. A second location has been made 1 miles south of No. 3 and somewhat higher on
