​​​​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).

Aliso Canyon Update

The Department of Conservation’s Division of Oil, Gas, and Geothermal Resources (Division) has completed its comprehensive safety review at the Aliso Canyon Storage Facility. With safety as our top priority, the Division’s extensive site inspections and review of Southern California Gas’s testing -- in consultation with the Lawrence Livermore, Lawrence Berkeley and Sandia National Laboratories -- was completed on January 17, 2017.

Regulators will not make a decision about whether injection of gas into the storage facility can resume until they review and respond to comments submitted by the public.

A webcast presentation of the rigorous testing done to all wells at the Aliso Canyon Storage Facility can be seen here:​.

Please join the Division’s Aliso Canyon Updates email list to receive updates.

Test results submitted by Southern California Gas and reviewed by Division of Oil, Gas, and Geothermal Resources staff are posted on this page.

Annual Well Stimulation Treatment Report Available

This annual report satisfies the legislative report requirements of Senate Bill 4 (Pavley, Chapter 313, Statutes of 2013) regarding well stimulation treatment. Part 1 of the report summarizes the objective and scope of this report. Part 2 provides a response to each legislative reporting requirement. The appendices provide references and sources of the data, as well as a glossary of terms used. During the reporting period, 579 well stimulation treatments were performed, all but one in western Kern County in relatively mature oil fields.

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.
