Los Angeles Basin

Approximately 20 percent of California Resources Corporation’s estimated proved reserves as of year-end 2015 were located in the Los Angeles Basin. We actively operate and develop 10 fields in this urban, coastal basin consisting of conventional primary, improved oil recovery, enhanced oil recovery and unconventional project types. We have a leading acreage position within the Los Angeles Basin with approximately 34,700 net acres, approximately half of which we hold in fee, and over 50 percent of the basin’s production comes from the fields we operate.

The Los Angeles Basin is a northwest-trending plain about 50 miles long and 20 miles wide on the coast of Southern California containing Miocene through Pleistocene sediments. The basin has great structural relief and complexity in relation to its geologic youth and small size and is noted for its prolific oil production. The Los Angeles Basin’s small areal extent, prolific source rocks, thick sandstone reservoirs and large anticlinal traps are considered a nearly ideal petroleum system. As a result, the Los Angeles Basin has one of the highest concentrations per acre of crude oil in the world with 68 fields named in an area of about 450 square miles. These accumulations of fine-grained sediments with high organic content, interlayered with coarser grained sands, contributed to the formation of large deposits of oil, including the Wilmington Field where we have significant operations. The Los Angeles Basin contains multiple stacked formations throughout its depths, and we believe that it provides a considerable inventory of existing field re-development opportunities as well as new play discovery potential.
