​​​​​​​​Welcome to the Division of Oil, Gas, and 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 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.

California Regulators Propose New Oil and Gas Rules

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. Draft regulations regarding idle wells and underground injection control have been released, while regulations for geothermal production are in the pre-rulemaking stage. Public comment details, drafts of the regulations, and other supportive documents can be found here. The public comment period for idle wells and underground injection draft regulations ended September 13. For pre-2018 rulemaking documents, please see the archive page.      

State Oil and Gas Regulators Form Office of Enforcement

The Department of Conservation (DOC) has launched an Office of Enforcement within its Division of Oil, Gas, and Geothermal Resources (DOGGR) to enhance compliance with public safety and environmental regulations and the administration of enforcement actions. The office, composed of engineering geologists and legal staff, will work with staff throughout DOGGR to identify and investigate violations and track compliance.


State Finalizes Underground Gas Storage Regulations

On October 1, rigorous new regulations aimed at protecting health and safety go into effect, concluding an effort that began during the Aliso Canyon leak of 2015-16. The regulations will become effective October 1, 2018.

“Our new regulations put the emphasis on proactively preventing leaks, and we believe they are the strongest protocols for natural gas storage in the U.S.,” State Oil and Gas Supervisor Ken Harris said. Harris leads the Division of Oil, Gas, and Geothermal Resources (DOGGR), part of the California Department of Conservation.

“The best science and engineering, as well as significant input from a broad spectrum of the public, went into developing these regulations,” he continued. “Our overriding goal is to ensure we keep the public and the environment safe, and prevent any future Aliso Canyon-like incidents.”


New Rules Strengthen DOGGR Oversight of Gas Pipelines 

New regulations for certain pipelines associated with California oil and gas production have been approved, giving Division of Oil, Gas, and Geothermal Resources (DOGGR) regulators additional tools to protect public health, safety, and the environment.

The rules, which go into effect October 1, 2018 were developed to fulfill requirements mandated in Assembly Bill 1420 (Salas, 2015). The legislation was drafted in response to a 2014 natural gas leak in a small pipeline in Arvin in Kern County. 

The regulations​:

- Address mechanical integrity testing (MIT) requirements for all in-service gas pipelines, regardless of diameter, that lie within a sensitive area. The Public Resources Code defines a sensitive area as that with pipelines near homes or other occupied structures.

- Require Pipeline Management Plans to be submitted to DOGGR to ensure that identified risks are adequately managed and that the pipeline characteristics and location information necessary to verify pipeline safety is readily available.

- Give local government or other state agencies the ability to petition the State Oil and Gas Supervisor to designate specified pipelines as being within a sensitive area.

Proposed Regulations for Underground Injection Control

The review process for proposed regulations governing underground injection control is underway. An independent panel comprised of experts in geology, toxics, the oil and gas industry, public health, and the environment is evaluating the proposed rules.

Here is an archived broadcast of the first meeting of the panel held May 29, 2018.

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

​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 Well Finder 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.

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.
