Oil and gas exploration, offshore southern California
Four local Tertiary basins comprise the regional Pacific Basin south of Point Conception: the San Diego trough and the offshore Los Angeles, Outer Banks, and Ventura-Santa Barbara Channel Basins. The San Diego trough has not been tested by deep wells. The offshore Los Angeles Basin produces oil and gas from Neogene sandstones in giant oil fields which extend on shore. The Outer Banks Basin is primarily a late cretaceous and Eocene-Oligocene basin which does not extend on shore; 6 test wells have been drilled since the 1975 sale, but no discoveries have been announced. The offshore Ventura-Santa Barbara Channel Basin produces oil and gas from Pliocene, Miocene, Oligocene, and Eocene sandstones and from fractured Monterey chert and siliceous shale of Miocene age; major future reserves are expected to be found in these reservoirs. 13 references.
