|Title / Description|
||California’s Geothermal Resources|
Selected geothermal research publications from the California Geological Survey.
||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.
New Data Reduction Tools and their Application to The Geysers Geothermal Field
Excel-based data-reduction and visualization tools. The tools are described in a paper presented at the 2005 World Geothermal Congress meeting in Turkey. Data from The Geysers Geothermal field are described.
Principles of Stratigraphic Nomenclature
Description of division stratigraphic nomenclature practices, based on the rules and policies of the Geologic Names Committee of the United States Geological Survey (1982).

|A Reservoir Assessment of The Geysers Geothermal Field|
Production history, subsurface geology, geophysics, reservoir assessment, and drilling technology are discussed for The Geysers Geothermal field. Twenty-seven figures, nine tables, nine plates, four photos (1981).
|Heat-Flow Mapping at The Geysers Geothermal Field |
A temperature-gradient map and a heat-flow map were drawn of The Geysers Geothermal field. Includes data from 187 temperature-gradient holes (1986).
||Geothermal in California|
Comic-book style introduction to geothermal resources in California, from formation to development. 4th-8th grade level or for anyone wishing a short review of the subject (1988).
||Survey of Nontechnical Geothermal Public Information-Worldwide|
The content and purpose of each entry are described in this anthology of nontechnical geothermal public information. Prices and ordering information are included (1990).
||A Geysers Album, Five Eras of Geothermal History |
Five eras of geothermal history at The Geysers Geothermal field are described. The first was the wilderness era; the second, use by Native Americans; the third, the age of tourism; the fourth, a 1920s electrical generation project; and the fifth, modern electrical generation (2010).
