This dataset contains active fault features compiled by the Arizona Geological Survey, and published as a Web feature service for the National Geothermal Data System. Fields in the Active Fault Feature Content Model will become XML elements in interchange documents for WMS simple features provided by a node in the USGIN network. Each feature includes a Fault Name, Symbol and Source. The dataset is spatially referenced to EPSG: 4326 (for interoperability). The data contained in the submitted dataset is available as an Excel Spreadsheet, Access Database (.mdb), ESRI service, WMS and WFS service.

The Department of Energy's EGS Strategic Plan anticipates that EGS experimentation in the United States will be underway by 2004 in areas within or adjaeent to commerciallydeveloped hydrothermal fields, and that an EGS demonstration plant will begin operating in 2008. Criteria for selecting sites for EGS experimentation focus on enhancing energy recovery at producing fields while advancing the EGS knowledge base incrementally towards a demonstration project. With input from field operators, basic characteristics and information on the type of EGS work that may be undertaken are presented for 15 producing fields and 2 unexploited fields. Six producing fields meet 90 - 100% of the site selection criteria and 9 meet 60 - 70%. The use of EGS techniques to supply an existing facility has the advantages of low cost, support from the geothermal industry and demonstration of applicability to a variety of conversion technologies. This approach seeks to reduce EGS risk and uncertainty, promoting the transition from research to commercial evelopment.

This report provides a compilation of geothermal well and spring information in Arizona up to 1933. This report and data base are a part of a larger congressionally-funded national effort too encourage and assist geothermal direct-use. In 1991, the U.S. Department of Energy, Geothermal Division (DOE/GD) began a Low-Temperature Geothermal Resources and Technology Transfer Program. Phase 1 of this program includes updating the inventory of wells and springs of then western states and placing this data into a digital format that is universally accessible to the PC.

Annual report shows summary of the pumpage and fluctuations of ground water levels in Arizona in 1955. Changes discussed for individual basins and areas. Illustrations of hydrographs of individual wells, graphs showing pumpage, graphs showing precipitation, maps showing contours of water level changes.

This drilling project in northwest Arizona consisted of 18 holes drilled to depths ranging from 1,341 to 5,491 feet. The holes were sited to determine the lateral extent of the Uranium-bearing strata. / Additional data to improve the resource estimates for the Date Creek and the Big Sandy basin.

This publication presents a tabulation of the temperature and associated data of subsurface rocks and two maps showing the location of wells for which temperature information is available in the files of the Oil and Gas Conservation Commission. Most of this information consists of the bottom hole temperatures measured by geophysical log surveys of wells drilled for oil, natural gas, and helium in the northeastern portion of the Colorado Plateau tectonic province of Arizona. It represents the first phase of a subsurface temperature project designed primarily for the use of earth scientists interested in the geothermal-energy potential of the state. The second phase of the project will present surface water temperature and associated data of numerous wells drilled for irrigation and other purposes located mostly in the Basin and Range tectonic province of Arizona.

"Identification of truly thermal springs is an indispensable aid in the assessment of a region's geothermal characteristics. Over the years numerous lists of thermal springs in Arizona have been compiled and we present yet another. Although the word thermal implies heat, there is considerable subjective or arbitrariness in its application. In geothermal work what is important is anomalous or unusual heat-something above a norm. A functional scheme has been devised that is useful in identifying those Arizona springs judged to be carrying anomalous heat. The method is readily applied to any new springs that may be encountered. The results of this updated version are shown in Table 1. Also, possible heat sources are briefly outlined in the text."
