GEOLOGY AND PRODUCTION HISTORY OF THE EAST BEVERLY HILLS OIL FIELD, LOS ANGELES BASIN, CA
East Beverly Hills Oil Field was the last field discovered in this northerly Los Angeles Basin productive trend that extends for 15 miles from Sawtelle to Los Angeles City oil fields. This trend is characterized by complex folding and faulting that occurred in the late Miocene and also in the Plio/Pleistocene. East Beverly Hills field is an asymmetric anticlinal fold with a nearly east/west strike. The structure has in excess of 2,000 of relief with the north limb dipping at a rate of 20-30 degrees north/northeast and the south limb vertical to locally overturned.
The productive horizons are Miocene Puente sands and Pliocene Repetto sands. Pliocene Repetto sands are productive predominately on the north flank of the structure from a subsea depth of 4,800. The main producing unit is the Miocene Hauser sand, which is present at a subsea depth of about 5,300 and has a gross thickness of 700. The lowest producing unit is the Miocene Ogden sand at a subsea depth of 7,200.
