Welcome to the Division of Oil, Gas, & Geothermal Resources

The Division oversees the drilling, operation, maintenance, and plugging and abandonment of oil, natural gas, and geothermal wells. The regulatory program emphasizes the wise development of oil, natural gas, and geothermal resources in the state through sound engineering practices that protect the environment, prevent pollution, and ensure public safety.

The Department of Conservation is underway in its Renewal Plan to strengthen and improve the state’s oversight of oil and gas production in California.

Oil and Gas Wells in California

All California oil and gas wells (development and prospect wells), enhanced-recovery wells, water-disposal wells, service wells (i.e. structure, observation, temperature observation wells), core-holes, and gas-storage wells, onshore and offshore (within three nautical miles of the coastline), located on state and private lands, are permitted, drilled, operated, maintained, plugged and abandoned under requirements and procedures administered by the Department of Conservation's Division of Oil, Gas, and Geothermal Resources (DOGGR).

State Considering Aquifer Exemption Expansions for Kern Oil Fields

The California Department of Conservation and State Water Resources Control Board are considering proposals to expand the current aquifer exemption designation for two Kern County oil fields: 1) the Santa Margarita formation in the Fruitvale Oil Field and 2) the Transition Zone in the Tejon Oil Field. Subject to approval by the U.S. Environmental Protection Agency, the proposed aquifer exemptions would allow the State, in compliance with the federal Safe Drinking Water Act, to approve Class II injection into the identified areas, either for enhanced oil recovery or for disposal of fluids associated with oil and gas production.

A public hearing about the Fruitval proposal was held August 15 and written comments were accepted until Monday, August 29. A public hearing about the Tejon proposal was held on September 12 and comments were accepted until September 26, 2016.

Visit this page to learn more about either of the proposals.

DOC Releases Discussion Draft Gas Storage Regulations

On July 8, the California Department of Conservation (DOC), Division of Oil, Gas, and Geothermal Resources (Division) publicly released pre-rulemaking draft regulations (a discussion draft) for the purpose of receiving public input on the development of updates to the regulations governing the Division’s natural gas storage program.

The release of this discussion draft initiated a public comment period that ended on August 22, 2016 at 5 p.m. The comments will be reviewed and considered as the Division updates the draft regulations. Information about the process for submitting comments is included in the notice below. The Division conducted two workshops to receive verbal and written input from interested parties, in Sacramento and Woodland Hills.

Testing Results of Aliso Canyon Wells Available

The Department of Conservation’s Division of Oil, Gas, and Geothermal Resources has ordered that all 114 injection wells be thoroughly tested for safety and competence before injection resumes into the Aliso Canyon natural gas storage field. The Division developed a protocol of six tests in consultation with the Lawrence Livermore and Berkeley National Laboratories. Test results are submitted by Southern California Gas, reviewed by Division staff, and then posted on this page, which is updated frequently. Wells must pass all tests within one year or be permanently sealed (plugged and abandoned).

View additional Aliso Canyon information – including biweekly reports that Southern California Gas must file on its progress toward completing the safety review.

​​​​State to Permanently Seal Two Deserted L.A. Oil Wells

The Department of Conservation/Division of Oil, Gas, and Geothermal Resources, in cooperation with the City of Los Angeles, will permanently seal two oil wells that were deserted by irresponsible operators and have seeped small amounts of gas in a residential neighborhood on Firmin Street. The wells pose no imminent danger but are a nuisance and will continue to deteriorate without intervention. For more information about the project, visit this page.
