Tectonic Controls on Reservoir Permeability in the Dixie Valley, Nevada, Geothermal Field
To determine factors controlling permeability variations within and adjacent to a fault-hosted geothermal reservoir at Dixie Valley, Nevada, we conducted borehole televiewer observations of wellbore failure (breakouts and cooling cracks) together with hydraulic fracturing stress measurements in six wells drilled into the Stillwater fault zone at depths of 2-3 km. Measurements in highly permeabl...
متن کاملHeating in a Geothermal Reservoir
A computer program in Visual Basic 6.0 is written to calculate steam tables for pure water up to 800oC and 1400 bar. The steam tables are created as a DLL (Dynamic Link Library) object with properties: temperature, pressure, specific volume, enthalpy and entropy for liquid and vapor phases, and liquidvapor state. The steam tables can be incorporated in any computer program on the Windows platfo...
متن کاملIntegrated Alteration Mineralogy and Fluid-inclusion Study at the Dixie Valley Geothermal Field. Nevada
Cuttings from geothermal wells in Dixie Valley, Nevada document the complex history of the Jurassic reservoir rocks now contained within the hanging wall of the Stillwater normal fault. Six stages of postOligocene alteration can be recognized on the basis of mineral paragenesis, rock associations, fluid-inclusion temperatures and apparent salinities. The paragenetic sequence from oldest to youn...
متن کاملPrecise Gravimetry and Geothermal Reservoir Management
Modern portable gravimeters can routinely achieve a 5 ugal uncertainty with careful measurement procedures involving multiple station occupations in the same day, and stacking of readings over at least 15 minutes during each occupation. Although further improvements in gravimeter accuracy are feasible, other practical factors relating to repeat surveys of geothermal fields make such improvement...
متن کاملAn Investigation of the Dixie Valley Geothermal Field, Nevada, Using Temporal Moment Analysis of Tracer Tests
The method of analysis of the first temporal moment (mean residence time) of tracer return data was utilized to investigate the swept volume and fluid velocity between pairs of injection and production wells in the Dixie Valley geothermal field. Calculations were made using a spreadsheet program available from the Idaho National Laboratory. Jointly sponsored industry–government research at the ...
