The Wilmington Oil Field, Oil Production and Subsidence Mitigation in an Urban Environment
Energy Resources Board
City of Long Beach
The Wilmington Oil Field is the largest in Southern California and among the very largest fields in the United States. The field is unique in that it underlies an urban city, a major port, and offshore recreational areas in full view of thousands of people. Over 2.8 billion barrels have been produced since the field was discovered in 1932. The field has an estimated original oil in place of 9 billion barrels. A consequence of the large production from shallow reservoirs was 29 feet of subsidence during a 20-year period from 1940’s to the 1960’s.
This talk will cover the history of subsidence mitigation in the Wilmington field and on-going techniques used to minimize future elevation changes, while maximizing economic oil recovery. The role of the City of Long Beach as Operator for the Wilmington Trust Properties will also be discussed.
John Jepson is a Senior Geologist for the Energy Resources Department of the City of Long Beach. As a member of the Subsidence and Reservoir team he is responsible for the design, mapping and analysis of the GPS elevation surveys of 260 benchmarks located from San Pedro to Seal Beach. He graduated from San Diego State University and is a Professional Geologist. John is a past chairman of the Los Angeles Basin Section of the Society of Petroleum Engineers. He is interested in oil field history and has led numerous field trips throughout the Los Angeles Basin.
