Oil, Gas & Geothermal - Getting Started

Website Information

The Division oversees the drilling, operation, maintenance, and plugging and abandonment of oil, gas, and geothermal wells. The regulatory program emphasizes the wise development of oil, gas, and geothermal resources in the state through sound engineering practices that protect the environment, prevent pollution, and ensure public safety.

Oil and gas operations are divided into six geographic districts. A district boundary map and contact information are listed on this page.   Latest Division news, including publications, changes to laws and regulations, and other developments are listed.
Information regarding drilling and operating oil and gas wells is provided for anyone interested in owning oil or gas wells in California.   Operators may download Division forms.
The Division has a program to reduce the number of idle wells by encouraging operators to reactivate or plug and abandon them. In addition, information on orphan wells can be found at this site.   Injection wells are used to increase oil recovery and safely dispose of the salt and fresh water produced with oil and natural gas.
Information may be found on annual reports, laws and regulations, instruction manuals, production statistics, technical reports, open-file reports, and videos.   The Division of Oil, Gas, and Geothermal Resources prepares and publishes oil, gas, and geothermal field maps for the State of California. The maps are updated on a regular basis and cost $3 apiece.
