Geology And Production History of the East Beverly Hills Oil Field, Los Angeles Basin, CA
BreitBurn Energy Company LLC, Los Angeles, CA
East Beverly Hills Oil Field is located in the northern Los Angeles Basin, approximately 7 miles west of downtown. The field was discovered in 1966 by Occidental Petroleum, drilling from an urban drill site along Pico Blvd. The exploratory well had an initial rate of production over 500 BOPD. Since then, nearly 100 wells from 5 urban drill sites have been completed in this field, encompassing 1,000 acres. It is estimated that the various reservoirs contain 600 MMBO in place of which about 111 MMBO has been produced to date.
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’.
