California Borehole Temperatures

Basic Information
Author: California Division of Oil, Gas and Geothermal
Description:This resource is a compilation of borehole temperature observations obtained from the California Division of Oil, Gas and Geothermal Resources wells database. Borehole temperatures were obtained from over 10,000 oil-and-gas wells, over 1,800 Geosteam thermal fields from geophysical logs provided by the DOGGR, Long Valley caldera geothermal well data provided by the USGS, and production data reports throughout California. Due to the large number of oil and gas wells in California, several wells were selected at random from each oil and gas field and wildcat wells to provide temperatures representative of the field. The selection process included wells that had electric or temperature geophysical logs and maximum borehole temperature reported. Maximum temperature for boreholes are recorded on geophysical logs viewable online at DOGGR. The borehole temperature data were compiled as interchange exchange data content for interoperability in the National Geothermal Data System; the data was published as an ESRI Service, a web map service, and a web feature service, and included in the AASG NGDS repository as an Excel workbook for download. The workbook contains 6 worksheets, including information about the template, notes related to revisions of the template, Resource provider information, the data, a field list (data mapping view) and a worksheet with vocabularies for use in populating the data worksheet (data valid terms). Fields in the data table include HeaderURI, WellName , APINo, OtherID, Operator, LeaseName, SpudDate, Status, Field, Latitude, Longitude, Measured Temperature, Measurement Date, Related Resources, and Source. This data was compiled by the Arizona Geological Survey and made available for distribution through the AASG National Geothermal Data Systems project.
