California Geysers Unit 15 and Adjacent Area Well and Field Records

Basic Information
Author: GEO Operator Corporation
Description:This resource is a metadata compilation of the California Department of Oil, Gas and Geothermal Resources (DOGGR) Geysers Unit 15 well records and field records. It provides access to the Unit 15 documentation as a cohesive collection of well data. The compilation was provided by the Arizona Geological Survey for submission to the National Geothermal Data System. GEO Operator Corporation (formerly Thermogenics, Inc. and Geothermal Resources International Operator Corporation) drilled steam production and injection wells in the northwestern portion of the Geysers geothermal field from 1967 to 1985. These wells produced steam that was sold to PG and Es power plant 15. Technical data and well cuttings were salvaged from an abandoned warehouse on the GEO Operator Corporation lease. These data have recently been scanned and added to the CA DOGGR existing scanned well records. A total of over 10,300 pages and over 340 logs are included in the scans. The reservoir engineering section alone contains over 3,300 pages of reservoir characterization, well testing, and related studies.The well cuttings have been preserved at the University of Utah Energy and Geoscience Institute. For access to the cuttings, please contact Joe Moore at jmoore@egi.utah.edu or 801-585-3540. For more information on this resource, please see the link provided.
