Year: 1978 An oil and gas exploration well, located near Jesup in Wayne County, Georgia (lat. 31/sup 0/32' N, long. 81/sup 0/43' W), was deepened and used for geothermal temperature-gradient measurements. The well was drilled from 4,009 to 4,341 feet, then diamond cored to 4,371 feet, 28 feet of core being obtained for analysis. After logging by the U.S.G.S. District Groundwater Office in Atlanta, the well was terminated with 3/sup 1///sub 2/'' tubing to 4,386 feet. The bottom-hole temperature was determined to be 60/sup 0/C (140/sup 0/F) at 1,331 meters (4,365 feet). Over the interval 47 to 1,331 meters (154 to 4,365 feet) the least-squares temperature gradient was 29.3 +- 0.14 /sup 0/C/km (1.61 +- 0.25 /sup 0/F/100 ft) Title: C. D. Hopkins, et al. , No. 2.

Year: 1978 A series of measurements was made in the exploratory well CGEH-1 at Coso Hot Springs. The temperature measurements provide estimates for the thermal equilibration of the well and indicate that the fractures intersecting the well have different temperatures. The hottest fractures are in the upper-cased portion of the well. Downhole chemical sampling suggests that the borehole still contains remnants of drilling materials. The well has never been extensively flowed at this time Title: Static Downhole Characteristics of Well CGEH-1 at Coso Hot Springs, China Lake, California Author: Goranson, C.

  	Citation × Citation Citation Abstract Copy Title: Geothermal Resource Exploration in Boise, Idaho Author: Nelson, L.B. Year: 1980 Exploratory drilling in Boise, Idaho, in the vicinity of the Boise Front Fault has confirmed the presence of a 170/sup 0/F (77/sup 0/C) geothermal resource below about 800 ft (244 m) near the Veterans Hospital of the Military Reserve Park. The Idaho National Engineering Laboratory (INEL), sponsored by the Department of Energy, drilled three exploratory slim holes and two deep exploratory test wells. Study results based on tests of the two exploratory-test wells are reported. Faulting related to the Boise Front Fault defines a major physiographic break in the area that acts as a subsurface conduit through which geothermal water circulates. Hydrologic tests indicate that rocks disturbed by the Boise Front Fault may be as much as ten times more permeable than those removed from the major structural lineament Title: Geothermal Resource Exploration in Boise, Idaho Author: Nelson, L.B.
