It is possible to design a canister to cool a borehole gravimeter for use in geothermal and high-temperature (up to 350/sup 0/C) gas wells. Repeat surveys with such a gravimeter could (1) help estimate ...
Citation -
This Open-File Report consists of fluid temperature logs compiled during studies of the geohydrology and low temperature geothermal resources of eastern Washington. The fluid temperature logs are divided ...
Citation -
Low temperature geothermal fluid is defined in OAR Chapter 690, Division 65 as any ground water used for its thermal characteristics that is encountered in a well with a bottom hole temperature less than ...

6. [Image] The Cody Hydrothermal System
The hot springs of Colter's Hell are the surface manifestations of a much larger hydrothermal system. That system has been studied to define its extent, maximum temperature, and mechanism of operation. ...Citation -
7. [Image] Interactive Fracture Design Model
A computer program is described that can be used to design a fracture stimulation treatment for a geothermal reservoir. The program uses state-of-the-art methods to calculate the temperature of the fracture ...Citation -
Feasibility studies of nuclear techniques applicable to the determination of geothermal formation temperature and two-phase brine flow downhole have been performed. The formation temperature gauging technique ...
Citation -
An assessment of the geothermal resources of Caliente, Nevada was made to provide information on resource characteristics and to site 2 (two) 500 ft (152 m) test wells to confirm the resource. The strategy ...
Citation -
Multielement geochemical analysis of drill cuttings from 18 shallow and 2 intermediate-depth temperature gradient holes outlines an area of anomalous geochemistry related to the fluid flow and temperature ...

11. [Image] Static Downhole Characteristics of Well CGEH-1 at Coso Hot Springs, China Lake, California
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 ...Citation -
The present status of the formation temperature gauge feasibility study is reported. It also demonstrates the feasibility of the technique in the simplified situations examined to date both analytically ...

13. [Image] Low-Temperature Geothermal Potential of the Ojo Caliente Warm Springs Area, Northern New Mexico
A detailed geochemical investigation of 17 waters (thermal and cold, mineralized and dilute) was performed in the Ojo Caliente-La Madera area. Two types of thermomineral waters have separate and distinctive ...Citation -
The Utah Geological and Mineral Survey (UGMS) has been conducting research to identify low-temperature geothermal resources in Utah as per U.S. Department of Energy (DOE) Contract OE-AS07-77ET28393. This ...

15. [Image] Drilling fluid/formation interaction at simulated in situ geothermal conditions. Final report
Interaction of drilling fluids with a geothermal reservoir formation can result in significant permeability impairment and therefore reduced well productivity. This interaction is studied under simulated ...Citation -
16. [Image] Annual Report on the Project to Design and Experimentally Test an Improved Geothermal Drill Bit
Progress is reported in a research and development program to design, build, and test an improved geothermal drill bit. The major tasks of the Phase I effort are entitled: failure mechanisms of existing ...Citation -
17. [Image] Geothermal District Heating Projects
The geothermal energy stored within the interior of the earth amounts to a significant quantity which, if fully exploited, could supply the energy needs of man for a millennia. Low temperature hydrothermal ...Citation -
18. [Image] Geotechnical Studies of Geothermal Reservoirs
Maximum temperatures found in the reservoir were approximately 700°F in the Imperial Valley, California, but drill bit temperatures may be considerably higher in the Geysers geothermal area. Temperatures ...Citation -
