Organization Title

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.

Well Stimulation- The Practice and the Regulation

With the passage of Senate Bill 4 (Pavley, Ch 313, Stats of 2013), California will have new rules for the practice of “well stimulation” activities undertaken by oil and gas operators. “Well stimulation” practices are defined by Senate Bill 4 (SB 4) and include hydraulic fracturing and other treatments that increase the flow of hydrocarbons (oil and natural gas) to wells and then to the surface for recovery. Find out more about well stimulation and the rules governing the practice here.

The Department's implementation of SB 4 includes:

  1. Interim Well Stimulation Regulations effective January 1, 2014. Find out more about those regulations here.
  2. Adoption of separate, permanent regulations for 2015 and beyond. Find out more about those regulations here.
  3. Development of an environmental impact report (EIR) by July 1, 2015. Find out more about the EIR development here.
  4. Web-based posting of public notices about well stimulation permits applied for and issued by the Division of Oil, Gas and Geothermal Resources. Find current well stimulation certifications here.

New Well Search Tools Available

Well Finder LogoThe Division of Oil, Gas, and Geothermal Resources has two new online tools that make finding information about California wells more convenient. The Division's Well Finder application shows every known oil and gas well in the state. Users can search for a well in a variety of ways and view production information, the well record, and notice/permit information, including whether the Division has been notified that well stimulation is being used.

Also now online is the Division's Interim Well Stimulation Treatment Notices Index, which allows users to view forms submitted by oil and gas operators to the Division about well stimulation operations, as required by the interim regulations supporting SB 4.

SB4 Interim Well Stimulation Treatment Regulations Compliance Workshop
(Posted 4/14/2014)

With the SB 4 emergency regulations now in-place, the Division of Oil, Gas, and Geothermal Resources (Division) is planning a workshop for industry representatives regarding the SB 4 Interim Well Stimulation Treatment Regulations.

This workshop will be held in Long Beach:

Date: Tuesday, April 22, 2014
Time: 9:00 a.m. - 1:00 p.m.
Address: TBD

The purpose of this workshop is for the Division to provide critical guidance to operators, and respond to questions regarding the interim regulations, their implementation procedures, and how to perform well stimulation treatments in compliance with the interim regulations in 2014.

Representatives of the State Water Resources Control Board will also be present to discuss and field questions about their role and required concurrence pursuant to the SB 4 mandates in 2014.

If you have any questions regarding this workshop, please contact Vincent Agusiegbe at (916) 323-0425 or Vincent.Agusiegbe@conservation.ca.gov.

DOGGR Announces New Assessment Rate
(Posted 6/11/2013)

The Oil and Gas Assessment rate for fiscal year 2013-2014 is 14.26683 cents per barrel of oil or 10 Mcf of natural gas produced. This is a 0.0020476 cent (1.456 percent) increase and so not significantly different from the previous fiscal year.

USGS Publishes Report on Stratigraphic Data from Oil and Gas Wells in Cuyama Valley and Surrounding Areas

The USGS has published the report Digital Tabulation of Stratigraphic Data from Oil And Gas Wells in Cuyama Valley and Surrounding Areas, Central California. USGS Open-File Report 2013-1084 includes stratigraphic information from 391 oil and gas wells in the Cuyama Valley in areas located in the southeastern Coast Range and north of the western Transverse Range and surrounding areas. Knowledge of the location and elevation of stratigraphic tops of formations throughout the basin is a first step toward understanding depositional trends and the structural evolution of the basin through time, and helps in understanding the slip history and partitioning of slip on San Andreas and related faults.

The report is available online only in electronic format at: http://pubs.usgs.gov/of/2013/1084/.
