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

The Division of Oil, Gas, and Geothermal Resources (DOGGR) 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 DOGGR.

Hot Topics

Proposed Regulations for Underground Injection Control

An independent review panel comprised of experts in geology, toxics, the oil and gas industry, public health, and the environment meets Monday, May 29, to begin the evaluation of proposed regulations governing underground injection control.

The panel, convened by the California Natural Resources Agency and the California Environmental Protection Agency, meets from 1-4p.m. in the State Resources Building auditorium (1st Floor), 1416 Ninth Street Sacramento, CA. The meeting will be streamed live on Cal Span.

Additional information about underground injection control and the panel can be found on the Natural Resources Agency website.


Public Input and Proposed Regul​​​​ations

The Department of Conservation and Division of Oil, Gas, and Geothermal Resources (DOGGR) are creating regulations to ensure public health and safety, environmental protection, and the conservation of resources. Regulations regarding natural gas pipelines and underground natural gas storage have advanced to the formal rulemaking stage. Regulations regarding idle wells, underground injection control, and geothermal production are in the pre-rulemaking stage. Public comment details, drafts of the regulations, and other supportive documents can be found here. For pre-2018 rulemaking documents, please see the archive page.      


WellSTAR Information

As part of its Renewal Plan, the Division is creating a modern data management system to help strengthen its oversight of California oil and  gas production and provide enhanced transparency to the public. DOGGR is in the midst of developing the Well Statewide Tracking and Reporting System, or WellSTAR. The cloud-based application will improve data collection and analysis; streamline operations and processes; and comply with new reporting regulations from SB 1281 and SB 4, along with other state and federal statutes. In developing this new tool, DOGGR is leveraging the experience of the Ground Water Protection Council (GWPC), which has helped implement similar data management systems in 23 states. The development and deployment of WellSTAR is taking place in four phases and will run through 2019. The public will be able to access data on WellSTAR by the end of October 2018.  Information is concurrently available on Wellfinder while the new system is being built.

Aliso Canyon Natural Gas Storage Facility

After putting numerous safeguards in place to protect public ​ safety and the environment - such as ongoing on-site inspections - DOGGR and the California Public Utilities Commission concurred that natural gas injection may resume at the Aliso Canyon storage facility, with significantly reduced storage capacity and maximum injection pressures.

Since the leak was plugged at the Los Angeles County facility, significant improvements and upgrades have been made to infrastructure, testing, operations, and monitoring to ensure safe operations. DOGGR completed a comprehensive safety review at Aliso Canyon, consulting with the Lawrence Livermore, Lawrence Berkeley, and Sandia National Laboratories on extensive site inspections and review of Southern California Gas's testing. 

Ongoing well testing results and additional information can be found on the Aliso Canyon Updates page.


Surface Expressions

The term surface expression refers to the flow of water and/or oil to the surface during the oil extraction process. The condition typically is associated with extractions using high-energy steam injection in brittle geologic formations such as those found in northern Santa Barbara County near Santa Maria and on the southwest end of the San Joaquin Valley, west of Bakersfield.

While most surface expressions occur in oilfields that are far from communities and homes, DOGGR has safeguards to prevent them from occurring to ensure worker safety and to protect the environment.

     
Hydraulic Fracturing and Other Well Stimulation Treatments

Regulations now in effect in California established stringent environmental standards for all oil and gas well stimulation treatments (WST), such as hydraulic fracturing. Permits are contingent upon a comprehensive series of criteria, including an engineering review and well integrity evaluation to ensure operations are confined to their geologic zones. Operators must disclose chemicals used and comprehensive post-stimulation testing must be conducted and reported to ensure groundwater is protected. A full list of permits that have been granted, chemical disclosures, and extensive information about WST are available on the Division's WST page.

 

Seeking Engineers, Geologists, Analysts

The Department of Oil Gas and Geothermal Resources has ongoing job openings for technical and management positions in all of our offices: Orcutt, Ventura, Cypress, Bakersfield, and Sacramento. Information about the positions and how to apply is available from the following links:

Production Based Reports​​

Legislatively Mandated Reports

  • 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.

  • ​This report, covering the period of April 1, 2017 to September 30, 2017, satisfies the legislative report requirements of Senate Bill 83 (Ch. 24, Statutes of 2015), providing permitting and program assessment information for the Underground Injection Control Program. Past reports for the UIC Program are available here.
