Papers - Review of Notable New California Fields - El Segundo Oil Field, California

El Segundo field is about 14 miles southwest of the central portion of the city of Los Angeles, immediately adjacent to the town of El Segundo and the Standard Oil Company's El Segundo refinery site. The field is served and bisected by several major highways connecting the beach cities on the west side of the Los Angeles Basin. The exact location of the field and its position with respect to other producing areas is shown on the map covering this portion of the Basin (Fig. I). The Republic Petroleum Co. discovered the first commercial production in the area when it completed its El Segundo No. 1 (sec. 18, T. 3 S. R. 14 W.) at a depth of 7402 ft. on Aug. 24, 1935, flowing at the rate of about 400 bbl. per day, 28" gravity oil. The producing horizon in this well consists of about 72 ft. of conglomerate and schist conglomerate situated below the nodular shale (Miocene). The true (or solid) schist (Franciscan) was encountered and penetrated some 20 ft. in the bottom of the hole. This paper gives a report on the history of development and oil production to date, and also submits the writer's interpretation of structural conditions as determined from such development. The limited development, together with the complex and variable nature of the producing horizon, makes any interpretation of the structure at present only tentative, and any forecast for a given well extremely hazardous. History of Oil and Gas Production The El Segundo field has produced approximately 1,920,000 bbl. of oil. It has 27 producing wells and 14 drilling wells or locations. The present daily rate of production is about 13,400 bbl. The production history of the field to date is shown in Table 1. The principal companies operating or owning leases in this field are: Caminol Company, Geo. F. Getty, Inc., Ohio Oil Co., Republic Petroleum Co., Pacific Western Oil Corporation, Royalty Service Corporation, Richfield Oil Corporation, Standard Oil Company of California, The Texas Company, Union Oil Company.
