Fluid Geochemistry at the Raft River Geothermal Field, Idaho: New Data and Hydrogeological Implications
Following a period of exploration and development in the mid-late 1970’s, there was little activity at the Raft River geothermal field for the next ~20 years. US Geothermal Inc. acquired the project in 2002, and began commercial power generation in January 2008. From mid-2004 to present, US Geothermal Inc. has collected geochemical data from geothermal and monitoring wells in the field, as well...
متن کاملComparison of Three Tracer Tests at the Raft River Geothermal Site
Three conservative tracer tests have been conducted through the Bridge Fault fracture zone at the Raft River Geothermal (RRG) site. All three tests were conducted between injection well RRG-5 and production wells RRG-1 (790 m distance) and RRG4 (740 m distance). The injection well is used during the summer months to provide pressure support to the production wells. The first test was conducted ...
متن کاملSpreadsheets for Geothermal Water and Gas Geochemistry
Two Excel spreadsheets released with this paper support many of the common graphical analyses of water and gas chemistry used to interpret hot spring, fumarole and well samples in geothermal exploration and development. Cross-plots and ternary diagrams are generated from measured concentrations of chemical species using formulas based on equilibrium reactions and empirical relationships. Typica...
متن کاملGeology and in situ stress of the MH-2 borehole, Idaho, USA: Insights into western Snake River Plain structure from geothermal exploration drilling
Project HOTSPOT, the Snake River Scientific Drilling Project (International Continental Scientific Drilling Program), tested for deep geothermal resources and examined the petrology of volcanic rocks with three drillholes in the central and western Snake River Plain (western USA). The MH-2 drillhole targeted fractured crystalline and hydrothermally altered basalt in the area of the Mountain Hom...
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...
