Proposed Changes to Geothermal Regulations
Division staff have proposed several changes to the Division of Oil, Gas, & Geothermal's geothermal regulations. The proposed changes can be viewed by clicking here. Please send any comments to Elizabeth Johnson (ljohnson@consrv.ca.gov) or Mike Woods (mwoods@consrv.ca.gov) by August 20, 2008.
Coproduction of Geothermal Power from Oil and Gas Fields in California: Hot water produced from oil and gas wells can be used to generate geothermal power under certain temperature and flow conditions. This report provides links to technical reports about produced water and reservoir temperatures from oil and gas fields in California. Links to electric logs and to information on temperature gradients in sedimentary basins within the State are also provided.
The Geothermal Hot Line
Published by the Division of Oil, Gas, & Geothermal Resources from 1971 through 1996, the Geothermal Hot Line has been scanned and is available online. To access the issues of Geothermal Hot Line, click here.
Amendment to Geothermal Laws Affecting Well Record Confidentiality
On September 26, 2007, SB 1051, which amends section 3752 of the Public Resources Code, was signed into law by Governor Schwarzenegger. Under the newly amended section 3752, the period of confidentiality for geothermal well records commences at the cessation of drilling operations. For more information, see the Notice to Geothermal Operators issued November 5, 2007.
Geosteam Back Online
Geosteam is now back online and can be used to access non-confidential scanned well records, including logs, and view monthly production and injection information.
Scanned Well and Field Data for Geysers Unit 15 Available
Technical data from wells formerly operated by GEO Operator Corporation were recently scanned and added to the Division's existing well records. These records, compiled by GEO Operator Corporation while conducting operations at the Geysers Unit 15, can be accessed by clicking here.
GEOTHERMAL FACTS
Geothermal Section oversees the drilling, operation, maintenance, plugging, and abandonment of geothermal wells on state and private lands to ensure public safety and protect underground and surface waters.
California is the United States' largest generator of electricity from geothermal energy. In 2006, California received nearly five percent of its electrical energy from geothermal resources (about 14,000 Gigawatt-hours). The state has over 600 active, high-temperature geothermal wells (with fluids over 212 ° F) and 230 injection wells.
