The Playa del Rey oil field is on Santa Monica Bay, about 15 miles SW. of Los Angeles. The sedimentary rocks of the field were deposited on the flanks and over the ridge of an erosional surface of Franciscan schist. A NW.-trending anticline resulted from deposition and compaction over the ridge. An apron of schistose clastic material was deposited in the littoral zone at the base of the ridge and in embayments formed by the lateral channels. Conformably overlying the basal conglomerate (productive lower zone) and unconformably overlying the schist is a dark brown, compact shale with abundant small lenticular streaks and nodules of calcium phosphate. The rest of the Miocene rock column is composed of about 500 ft of hard, compact black shale and sandy shale, which is conformably overlain by the typical Los Angeles-basin Pliocene and Pleistocene rocks. The upper oil zone is in the lower Pliocene. The Playa del Rey Field is productive from both the lower zone and from sedimentary rocks of the anticline. There are widely varied porosity and permeability values throughout the Del Rey Hills area. That part chosen for the gas-storage project is where the basal conglomerate overlying the Franciscan schist is overlain by the nodular shale.
