Low-Temperature Geothermal Reservoir Site Evaluation in Arizona

The present Arizona geothermal energy program was initiated in response to prior geothermal research and reconnaissance programs conducted primarily under the aegis of the federal government. The initial program was extremely limited in scope, but expansion during the past year to six months has been both rapid and continuing. Early on the program was expanded to include the entire state of Arizona. During the period covered by this report, February 1 to April 30, 1978, a third geologist, James C. Witcher, joined the professional staff, and William L. Weibel began as a half-time graduate assistant. Two projects were completed during this quarter. The chapters in this report, Preliminary Map - Geothermal Energy Resources of Arizona by W. R. Hahman , Sr. and Thermal Gradient Anomalies in Southern Arizona by Salvatore Giardina, Jr. and J. N. Conley, detail the results. Following these are project reports on continuing phases of the overall program. Report contains preliminary geothermal resource map of Arizona; geothermal well temperatures, and thermal gradient models for multiple locations in Arizona, and a ranking of geothermal resources. Also, a Landsat lineament map of Arizona.Documents in the AZGS Document Repository collection are made available by the Arizona Geological Survey (AZGS) and the University Libraries at the University of Arizona.
