The Wilmington oil field is in the Los Angeles basin of southern California, one of the most prolific oil-producing basins of the world and considered to be an example of optimum conditions in the habitat of oil. The Wilmington structure, discovered in 1936, is a broad, asymmetrical anticline broken by a series of transverse normal faults which divide the producing beds into many separate pools. The 7 major producing zones range in age from middle Miocene to early Pliocene. Deposition of approximately 1,800 to 2,000 ft of nearly horizontal beds on top of the unconformity between the lower Pliocene Repetto beds and the upper Pliocene middle Pico Formation conceals the Wilmington anticline from the surface. The effectiveness of the faults as barriers to oil and gas accumulation in the field is significant. The development program in the field has been based primarily on segregation of the pools by fault blocks and zones. The Wilmington oil field has produced more than 1.1 billion bbl of oil.
