Economic analysis for utilization of geothermal energy by North Dakota Concrete Products Co.

Description: North Dakota Concrete Products Company uses a steam curing process that accelerates the concrete curing so that 28-day strength is obtained within 24 hours. The cost of energy required to accomplish this is significant, amounting to approximately $80,000 in 1980. The present boilers are oil fired. Recently, fuel oil prices have increased substantially. Further, supply shortages in the past have threatened plant production. The purpose of this study was to evaluate the economic feasibility of us… more

Reserves in western basins

Description: This project requires generation of producible tight gas sand reserve estimates for three western basins. The requirement is to perform such reserve estimates using industry accepted practices so that results will have high credibility and acceptance by the oil and gas industry. The ultimate goal of the project is to encourage development of the tight gas formation by industry through reduction of the technical and economic risks of locating, drilling and completing commercial gas wells. The th… more

Controlled Source Electromagnetic Methods in Geothermal Exploration

Description: The objective of this manuscript is to sketch the problems inherent in application of controlled source electromagnetic methods (CSEM) to geothermal exploration. Measurements have been made in both the time and frequency domains with time domain measurements currently enjoying an advantage over frequency domain measurements for shallow applications. Application of CSEM methods is impeded by natural field, electrification, geological, cultural, and topographic noise. Lateral resolution of parame… more

Direct utilization of geothermal resources at Warm Springs State Hospital, Warm Springs, Montana. Final report, January 31, 1979-June 30, 1983

Description: Several decades ago the water from a natural hot spring was piped to the Warm Springs State Hospital barn and greenhouse and eventually into the domestic water supply for showers. The Montana Department of Natural Resources and Conservation (DNRC) funded a feasibility study on potential development of the geothermal resource from monies originating from coal severence taxes. The results of the feasibility study were subsequently utilized in obtaining a $721,122 award from the Department of Ener… more

Geothermal resources of the Wind River Basin, Wyoming

Description: The geothermal resources of the Wind River Basin were investigated. Oil-well bottom-hole temperatures, thermal logs of wells, and heat flow data have been interpreted within a framework of geologic and hydrologic constraints. Basic thermal data, which includes the background thermal gradient and the highest recorded temperature and corresponding depth for each basin, is tabulated. Background heat flow in the Wind River Basin is generally insufficient to produce high conductive gradients. Only w… more
