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).

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 will be updated frequently. Wells must pass all tests within one year or be permanently sealed (plugged and abandoned).
additional Aliso Canyon information – including biweekly reports 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

Officials Confirm Gas Leak is Sealed
State regulators including the Department of Conservation’s Division of Oil, Gas and Geothermal Resources (Division) on February 18, 2016 provided public notice that the leaking well (SS25) at the Aliso Canyon Gas Storage Facility in Los Angeles County has been successfully sealed.
Natural Gas Storage Rulemaking
DOC’s Division of Oil, Gas, and Geothermal Resources is preparing to undertake rulemaking to make significant revisions to the regulations governing the Division’s Gas Storage Program. This rulemaking effort will build upon the requirements adopted by emergency rulemaking to update regulations and address concerns identified by the Division and other key stakeholders.
The document outlines the Division’s immediate regulatory goals. Public input was accepted until March 18.
First Annual Report on Well Stimulation Available
The Division of Oil, Gas, and Geothermal Resources has submitted to the state legislature an
annual report on its well stimulation treatment (WST) regulatory program, required under Senate Bill 4. Signed into law by Governor Brown in September 2013, SB 4 established the most comprehensive regulatory program for the use of hydraulic fracturing and other stimulation techniques in the United States. The report includes context and background about the development of the regulations and a significant amount of data about the use of WST in California.
DOC Issues Oil & Gas Renewal Plan, Report to Legislature
Building on the ongoing effort to strengthen and improve the state’s oversight of oil and gas production, the California Department of Conservation on October 8 released a Renewal Plan to overhaul its regulatory program and continue refocusing on the guiding principles of environmental protection and public health. The Renewal Plan, along with the ongoing reform efforts, also will help fix various regulatory problems identified in a report submitted to the Legislature today under Senate Bill 855 (2010) that directed the Department to report on the Division of Oil, Gas, and Geothermal Resources’ (DOGGR) enforcement and permitting of underground injection control.
The Renewal Plan for DOGGR includes the following elements and actions:
- Completing a review of aquifer exemptions under the Safe Drinking Water Act and performing a project-by-project review while ensuring that any approval letters clearly outline conditions of the permit.
- Developing and updating regulations for hydraulic fracturing and underground injection control that are more heavily science-based and reflect ongoing technological developments.
- Establishing a standard practice for record-keeping and workforce training to boost transparency and ensure consistent practices locally and statewide.
- Building a publicly accessible online database of decades of paper records and a system for modern data collection and retrieval going forward.
- Meeting aggressive deadlines for new regulations, public input and well evaluations.
The report to the Legislature focuses on DOGGR’s enforcement and permitting of underground injection control (UIC), a process used to increase oil production and to safely dispose of the salt and fresh water brought to the surface with oil and natural gas. The law directed DOC to report on permitting and enforcement statistics and to provide a program assessment and an action plan to address that assessment.
State Regulators Send Aquifer Exemption Proposal to U.S. EPA
The California Department of Conservation/Division of Oil, Gas, and Geothermal Resources (“Division”) and State Water Resources Control Board on February 8, 2016 submitted a proposal to the U.S. Environmental Protection Agency requesting to expand an aquifer exemption designation for the Dollie sands of the Pismo formation in the Arroyo Grande oil field. The field is in unincorporated San Luis Obispo County near the intersection of Ormonde Road and Price Canyon Road. The proposed aquifer exemption would allow the State, in compliance with the federal Safe Drinking Water Act, to approve Class II injection into the identified area, either for enhanced oil recovery or for injection disposal of fluids associated with oil and gas production.

Interested Parties List
To receive emailed notices about future aquifer exemption activities, please send an email to
email@example.com. Please specific whether you are interested in these activties in a specific oil field, in a county or community, or on a statewide basis.

SB 1281 Data and Report Available
The Department of Conservation (DOC) is making available comprehensive data on water use related to oil and gas production This is the first report to be posted as a result of recent legislation (Senate Bill 1281; Pavley, 2014), which requires self-reported data from industry. The report includes data from about 60 percent of California oil and gas operators, and accounts for approximately half of the overall expected reported water volumes for the first quarter of 2015. The report distinguishes between water brought to the surface during oil or gas exploration and production that might be used for agriculture or other beneficial uses and that which has no potential beneficial use because of its naturally-occurring salt or mineral content.
