Apparatus for simultaneously measuring electrical conductivity and oxygen fugacity

Description: Electrical conductivity studies of silicates are useful in determining temperature vs depth in the earth. Realistic laboratory measurements of conduction mechanisms require that exact determinations of oxygen fugacity (fo{sub 2}) be made in the experimental environment. An apparatus is described that monitors system fo{sub 2} with a calcia-doped zirconia-oxygen cell while measuring electrical conductivity of iron-bearing silicates at high temperature (greater than 1000 K). The fo{sub 2} calcula… more

National forecast for geothermal resource exploration and development with techniques for policy analysis and resource assessment

Description: The backgrund, structure and use of modern forecasting methods for estimating the future development of geothermal energy in the United States are documented. The forecasting instrument may be divided into two sequential submodels. The first predicts the timing and quality of future geothermal resource discoveries from an underlying resource base. This resource base represents an expansion of the widely-publicized USGS Circular 790. The second submodel forecasts the rate and extent of utilizati… more

Progress of the LASL dry hot rock geothermal energy project

Description: Under sponsorship of the Division of Applied Technology of AEC, Los Alamos Scientific Laboratory is investigating the possibilities and problems of extracting energy from geothermal reservoirs which do not spontaneously yield useful amounts of steam or hot water. The system for accomplishing this which is being developed first is a pressurized-water circulation loop intended for use in relatively impermeable hot rock. It will consist of two holes connected through the hot rock by a very large h… more

Geothermal Project. Final report

Description: The project was designed to take 95/sup 0/F water from an existing well and process it through a heat exchanger carrying supply water for our boiler make up and domestic hot water systems. The temperature of this water runs from 55/sup 0/F to 65/sup 0/F. In operation it was possible to raise the temperature of this water an average of approximately 12/sup 0/F. The amount of energy captured was recorded and it was found that one can capture approximately 199 x 10/sup 6/ Btu/Mo. Using current ene… more

Removal of H/sub 2/S from geothermal steam. Semi-annual report, April 1-October 31, 1975

Description: The program objective is to identify and evaluate a technique to remove hydrogen sulfide from geothermal steam before it is used for power generation. The last six months were spent in the literature search, sorbent preparation and evaluation, and construction of an experimental apparatus. Zn0, mentioned in the original proposal as a good candidate for H/sub 2/S adsorption, was verified as such by the literature search and laboratory experiments. However, regeneration of sulfided sorbent proved… more

High-temperature explosive development for geothermal well stimulation. Final report

Description: A two-component, temperature-resistant liquid explosive called HITEX has been developed which is capable of withstanding 561/sup 0/K (550/sup 0/F) for 24 hours in a geothermal environment. The explosive is intended for the stimulation of nonproducing or marginally producing geothermal (hot dry rock, vapor-dominated or hydrothermal) reservoirs by fracturing the strata in the vicinity of a borehole. The explosive is inherently safe because it is mixed below ground downhole from two nondetonable l… more
