Oil, Gas & Geothermal- About Us

The Division of Oil, Gas, and Geothermal Resources (DOGGR) was formed in 1915 to address the needs of the state, local governments, and industry by regulating statewide oil and gas activities with uniform laws and regulations. The Division supervises the drilling, operation, maintenance, and plugging and abandonment of onshore and offshore oil, gas, and geothermal wells, preventing damage to: (1) life, health, property, and natural resources; (2) underground and surface waters suitable for irrigation or domestic use; and (3) oil, gas, and geothermal reservoirs. Division requirements encourage wise development of California’s oil, gas, and geothermal resources while protecting the environment.

The Division’s programs include: well permitting and testing; safety inspections; oversight of production and injection projects; environmental lease inspections; idle-well testing; inspecting oilfield tanks, pipelines, and sumps; hazardous and orphan well plugging and abandonment contracts; and subsidence monitoring.

DOGGR is the repository for oil, gas, and geothermal well information and publishes statistics on drilling, production, and injection. General information, technical reports, and statewide maps with locations and status of all oil, gas, and geothermal wells are also available.

Division mandated responsibilities are in Section 3000 et seq. of the Public Resources Code and Title 14, Chapter 4 of the California Code of Regulations. For additional information, click here for our contact page.

To date, about 210,000 oil, gas, and geothermal wells have been drilled in California and around 88,500 are still in use. About 4,680 new wells were drilled in the state in 2012. The Division oversees around 570 companies that operate the wells. Daily oil production in 2012 was 541,000 barrels, placing California fourth among oil producing states. California is an important state for geothermal energy as well, generating more electricity from geothermal resources than any other state or nation.

There is no statewide severance tax on oil and gas production in California. There are ad valorem (property) taxes in California, administered by each county tax assessor.

There is a small statewide assessment on oil and gas produced that goes to support the Department of Conservation’s Division of Oil, Gas, and Geothermal Resources (Division), and is levied pursuant to Article 7, Division 3, of the Public Resources Code.

Annually, the Division presents Outstanding Field Lease and Facility Maintenance Awards to oil, gas, and geothermal operators. The awards recognize lease maintenance efforts that enhance safety and environmental protection above and beyond what is required.
