The Tulare Lake field is located in Kings County, California, on the west side of the San Joaquin Valley and 10 mi east of the Kettleman Hills (North Dome) field and 30 mi southeast of the city of Coalinga. The field was discovered by Husky Oil Co. (Marathon) in October 1981 with the completion of the Boswell 22-16, Sec. 16, T22S, R20E from sands in the Burbank formation of Oligocene geologic age.

Chevron U.S.A. offset the Husky discovery well with the completion of the Salyer 678X, Sec. 8, T22S, R20E, in May 1983. Both Chevron and Husky have continued an orderly development of the field, and to date Chevron has 9 producing wells and Husky 10 producing wells.

Production is found in the Burbank formation at a vertical depth below 12,800 ft. The entrapment of hydrocarbons is caused by a low amplitude, seismically subtle, anticlinal fold trending northwest/southeast. Isochore maps of the Burbank formation show that stratigraphy is important in the distribution of the four producing sand intervals. Oil gravities from the sands vary 39° API to 51° API and the GOR ranges from 1,050 to over 5,500. As of January 1, 1984, the field has a cumulative production of 1.7 million bbl of oil and 3.5 billion ft³ of gas.
