West Division

An Overview of our Properties in California

Seneca Resources’ West Division was established in 1987 as a result of the acquisition of several properties from Argo Petroleum in Ventura County, Calif.

In 1998, Seneca Resources expanded into Kern County, Calif., by acquiring the HarCor, Whittier and Bakersfield Energy companies. More recently we acquired Ivanhoe Energy USA in 2009. In 2012, a portion of the Coalinga oil field, located in Fresno County, Calif., was acquired from Chevron U.S.A. Inc., a subsidiary of Chevron Corporation. That same year, Seneca Resources was named Operator of the Year by California’s Bureau of Land Management.

Seneca Resources’ West Division operations are focused on the development of these properties along with seeking acquisition of low- to moderate-risk properties throughout all the San Joaquin basin in California. Since 1998, we have continued to maximize returns from our California holdings by optimizing lifting costs and drilling more than 700 new wells.

The West Division fields are predominately oil-producing properties displaying long-life reserves with low decline rates and low operating costs. As such, these assets provide a solid base and strong cash flow for Seneca Resources.
