Multielement geochemistry of three geothermal wells, Cove Fort-Sulphurdale geothermal area, Utah

Description: Multielement geochemical analysis of drill cuttings from three geothermal wells, Utah State 42-7, Utah State 31-33 and Forminco No. 1, in the Cove Fort-Sulphurdale KGRA, Utah, demonstrates that the distributions of different elements are the result of different chemical processes operating throughout the geologic history of the area. Statistical analysis of geochemical-data distributions confirm the presence of several distinct element associations. Of the 36 elements determined on the samples,… more

Preliminary plasma spectrometric analyses for selected elements in some geothermal waters from Cerro Prieto, Mexico

Description: Water samples collected from geothermal power production wells at Cerro Prieto, Mexico, were analyzed for selected elements by dc argon plasma emission spectroscopy. Spectral interferences due to the presence of high concentrations of Ca, Si, Na and K in these waters affected the apparent concentration values obtained. These effects were evaluated and correction techniques were developed and applied to the analytical values. Precipitates present in the samples at the time of analysis adversely … more

Trace element and isotope geochemistry of geothermal fluids, East Rift Zone, Kilauea, Hawaii

Description: A research program has been undertaken in an effort to better characterize the composition and the precipitation characteristic of the geothermal fluids produced by the HGP-A geothermal well located on the Kilauea East Rift Zone on the Island of Hawaii. The results of these studies have shown that the chemical composition of the fluids changed over the production life of the well and that the fluids produced were the result of mixing of at least two, and possibly three, source fluids. These sou… more

Oxygen isotope exchange in rocks and minerals from the Cerro Prieto geothermal system: indicators of temperature distribution and fluid flow

Description: Oxygen isotopic compositions have been measured in drill cuttings and core samples from more than 40 wells ranging in depth to more than 3.5 km in the Cerro Prieto geothermal field. Oxygen isotopic profiles of pore-filling calcites in sandstones appear to be a reliable measure of the recent equilibrium temperature distribution in the field before production began. From these data, a detailed, three-dimensional map has been developed, showing the equilibrium temperatures in the geothermal field.… more

Survey of helium in soils and soil gases and mercury in soils at Roosevelt Hot Springs Known Geothermal Resource Area, Utah

Description: The concentrations of helium and mercury in soils and of helium in soil gases were surveyed in part of the Roosevelt Hot Springs Known Geothermal Resource Area to see what relationship helium and mercury concentrations might have to geothermal features of the area. High concentrations of helium occurred over the producing geothermal field, in an area of high temperature gradients. Low concentrations of helium in soils occurred over an area of visible hydrotheormal activity. High concentrations … more

Chemical analyses and preliminary interpretation of waters collected from the CGEH No. 1 geothermal well at Coso, California

Description: The chloride-rich water obtained in 1967 from the shallow (114.3 m) Coso Hot Springs well No. 1 comes from a deep aquifer with a temperature at least as high as about 240/sup 0/ and possibly higher than 275/sup 0/C. Similar, but slightly diluted and cooled chloride-rich water enters the 1477-meter deep CGEH No. 1 well drilled in 1977 about 3.2 km to the west of the 1967 well. From the data in hand the Coso geothermal system appears to be a hot water type. The surface expression of fumarole and … more

Chemical and isotopic data for water from thermal springs and wells of Oregon

Description: The thermal springs of Oregon range in composition from dilute NaHCO/sub 3/ waters to moderately saline CO/sub 2/-charged NaCl-NaHCO/sub 3/ waters. Most of the thermal springs are located in southeastern or southcentral Oregon, with a few in northeastern Oregon and near the contact of the Western Cascades with the High Cascades. Thermal springs in the central and northern parts of the Cascades generally issue moderately saline NaCl waters. Farther south in the Cascades, the thermal waters are h… more

Definition of Engineering Development and Research Problems Relating to the Use of Geothermal Fluids for Electric Power Generation and Nonelectric Heating

Description: The use of geothermal fluids for electric power generation and nonelectric purposes causes problems not normally encountered when pure water is used for similar purposes. These problems must be identified and means developed to overcome them before geothermal energy resources can become an important source of electric power or thermal energy in the United States. Research and development projects aimed at solving problems arising from the use of geothermal fluids from known sources in the Unite… more
