The Wilmington Field has the largest production in net barrels of oil of any field in California. Cumulative production to Jan. 1, 1965, was 1,013,500,000 bbl of oil and about 843 MMcf of natural gas. Peak production was reached in 1951. The discovery well was completed in 1932, and by the end of 1964, 3,280 wells had been drilled in the field 2,583 of which still were considered active. The Wilmington field is on a well-developed, highly faulted anticline. All of the larger faults are normal. The basement rock in the field is Jurassic schist. It is overlain by about 4,000 ft of Miocene rock; 2,000-2,500 ft of Pliocene rock; and 1,000 ft of sand, gravel, and clay of Pleistocene and Recent ages. Oil production comes from 7 major producing zones of Pliocene and Miocene ages and from the Jurassic basement. Wilmington is among the few huge fields with initial gas reserves of more than 1 trillion cu ft; however, it is essentially an oil field. Average gas-oil ratio for 1964 was 216 cu ft/bbl. Remaining gas reserves at the end of 1964 were estimated at 195 billion cu ft.
