This dataset contains information on the location and heat characteristics of known geothermal and heat flow wells in the state of Washington. This dataset includes borehole and water well temperature information obtained from the Washington State Department of Ecology (ECY), Washington Division of Geology and Earth Resources Open File Report 94-11 (OFR 94-11), Southern Methodist University (SMU) Regional Heat Flow Database, and the U.S. Geological Survey. We also include unpublished data on file with the Division. Data from these sources were incorporated into this database only if a calculated gradient or an assumed bottom-hole temperature were recorded. We use the term 'assumed' to denote that the location of the temperature measurement within the borehole is assumed to be the bottom, although this is generally unknown; temperatures from this dataset should be considered mininum bottom-hole temperatures. Scanned geophysical logs are available for some of these locations through related data tables. In addition, temperature-depth plots are available for many boreholes. Much of the data is located within central and eastern Washington.

This is the California document metadata as an Excel files listing all documents gathered for Year 1 of the DOE NGDS project. Documents available in the USGIN catalog.

This Geothermal Permitting Guide was created as a reference tool for geothermal stakeholders interested in developing low temperature direct use and/or power production projects. It addresses the environmental regulatory requirements beginning after acquisition of the land and/or mineral rights. Organized by development activity, it begins with resource exploration and continues to well abandonment and project closure. No one set of standard regulations applies to geothermal projects due to the differences in land and/or mineral rights ownership, location and resource chemistry. Geothermal resources in California occur in disparate environments from mountainous to desert terrains. The resource also differs from being liquid dominated high or low temperature to steam-dominated high temperature. Regional regulators such as counties, regional water quality control boards and air districts develop regulations based on the needs of their jurisdictions. The document contains websites and regulatory citations as statutes and regulations change.

This paper presents the initial results of a survey of the occurrence and characteristics of geopressured fluid resources in California using the publicly-available database involving more than 150,000 oil and gas wells drilled in the State. Of the 975 documented on-shore oil and gas pools studied, about 42% were identified as potentially geopressured. Geothermal gradients in California oil and gas fields lie within the normal range of 1°F to 2°F per 100 feet. Except for the Los Angeles Basin, there was no evidence of higher temperatures or temperature gradients in geopressured pools. The porosity of geopressured pools shows the same normal distribution as for normal pressured pools, with a mode in the range of 20 to 25%. The salinity distribution of both the geopressured and normal pressured pools appear to be bimodal, each with two peak ranges of 0 to 10,000 and 25,000 to 30,000 ppm.
