Power Potential of Geothermal Wells Related to Reservoir Temperature
Abstract: For equal flows of hot water wells, the electric power which can be generated increases with feed water temperature. However, high temperature wells discharge greater flows than that of lower temperature wells of similar permeability, with the result of enhanced power potential. In fact, where fluids are exploited utilizing two-stage flash, these factors combine to give a power potential which is proportional to the cube of the feed water temperature in degrees celsius. Hence a feed of 315 C would generate twice the power of that of water at 250 C for wells of good permeability and where the reservoir exists under conditions of boiling point with depth. Higher temperature water (exceeding 300 C) has, however, a commensurate higher tendency to mineral deposition in reinjection water lines and this disposes design to single-stage flash with slightly reduced power, compared with the two-stage alternative.

Use of an acoustic borehole televiewer to investigate casing corrosion in geothermal wells
Corrosion of well and surface equipment due to the presence of hot, corrosive brines is one of the major problems facing geothermal operators. For wellbore casing, this problem is complicated by the fact that in-place inspection is difficult at best. In an attempt to improve this situation, a prototype acoustic borehole televiewer designed to operate in geothermal wells was used to study the corrosion damage to casing in three commercial wells. The results of this experiment were promising. The televiewer returns helped to define areas of major corrosion damage and to indicate the extent of the damage. This paper briefly discusses the corrosion problem, describes the acoustic borehole televiewer, and then summarizes the results of the field test of the televiewer's capability for investigating corrosion.

Use of inhibitors for scale control in brine-producing gas and oil wells
Field and laboratory work have shown that calcium-carbonate scale formation in waters produced with natural gas and oil can be prevented by injection of phosphonate inhibitor into the formation, even if the formation is sandstone without calcite binging material. Inhibitor squeeze jobs have been carried out on DOE's geopressured-geothermal Gladys McCall brine-gas well and GRI's co-production wells in the Hitchcock field. Following the inhibitor squeeze on Gladys McCall, the well produced over five million barrels of water at a rate of approximately 30,000 BPD without calcium-carbonate scaling. Before the inhibitor squeeze, the well could not be produced above 15,000 BPD without significant scale formation. In the GRI brine-gas co-production field tests, inhibitor squeezes have been used to successfully prevant scaling. Laboratory work has been conducted to determine what types of oil field waters are subject to scaling. This research has led to the development of a saturation index and accompanying nomographs which allow prediction of when scale will develop into a problem in brine production.

Mineral Resources of the White Rock Range Wilderness Study Area, Lincoln County, Nevada, and Beaver and Iron Counties, Utah
From summary: The White Rock Range Wilderness Study Area (NV-040-202/UT-040-216) is in Lincoln County, Nevada, and Beaver and Iron Counties, Utah, along the southern Nevada-Utah state line. Ursine, the town nearest to the study area, is about 15 mi (miles) southwest of the study area; the larger town of Pioche is about 30 mi southwest of the study area on Nevada Highway 322. A joint mineral resource appraisal of the 23,625 acre wilderness study area was completed in the summers of 1984 and 1985 by the U.S. Geological Survey and U.S. Bureau of Mines. The White Rock Range Wilderness Study Area has no identified mineral resources and has low mineral resource potential for metals; the potential for oil and gas, coal, and geothermal energy is also low.

Crosswell seismic measurement of transverse isotropy in V/sub p/ and Q/sup p/
Crosswell seismic measurements of apparent seismic Q/sub p/, V/sub p/, and V/sub s/ were made at the DOE Multi-Well Experiment (MWX) site near Rifle, Colorado. The MWX wells penetrate gas-bearing low permeability sandstones in the Mesa Verde formation at depths between 1950-2010 meters. Numerous measurements of Q/sub p/ were made between angles of 45 and 135 degrees measured from vertical using a modification of the technique of Fehler and Pearson (1984) in which measurement of P-wave amplitude permits the calculation of Q/sub p/, once compensation has been made for the radiation pattern of the source and geometric spreading. The magnitude of Q/sub p/ and V/sub p/ are found to change with propagation angle. Minimum values of Q/sub p/ and maximum values of V/sub p/ were measured parallel to sedimentary layering (15 and 4.75 km/s, respectively). A roughly linear increase in Q/sub p/ and a decrease in V/sub p/ occurs with increasing inclination of propagation paths to horizontal bedding planes. At 50 degrees from vertical a 90 percent increase in Q/sub p/ and a 7 percent decrease in V/sub p/ relative to values in the horizontal direction were measured. No change in V/sub s/ was observed. 12 refs., 3 figs., 1 …

Geothermal enhancement of mineral processing in Nevada: Final report, April 25, 1985-June 30, 1986
This report reviews mineral recovery techniques practiced at active mines throughout Nevada and determines those that may be enhanced by the application of geothermal heat energy from a nearby resource. Of the thirty-two active precious metal mines identified, ten have hot water on or near the property and could potentially benefit. A second purpose was to collect ore samples and geothermal fluids, determine if they are compatible in the hydrometallurgical process, and carry out laboratory tests to determine the effects of heating on recovery rates. In addition, interfering or counterproductive factors were also identified. The laboratory work consisted of measuring the effects of thermally enhancing two hydrometallurgical processes; cyanide heap-leaching of gold and silver ores and bacterial leaching of sulfide rich gold ores. Thermally enhanced cyanide heap-leaching of gold and silver ores produced increases in extraction ranging from 8 to 20% for gold and 17 to 40% for silver. The temperature required for these increases is 35/sup 0/C to 40/sup 0/C, well within the range of available geothermal resources.

Low-temperature geothermal assessment of the Santa Clara and Virgin River Valleys, Washington County, Utah
Exploration techniques included the following: (1) a temperature survey of springs, (2) chemical analyses and calculated geothermometer temperatures of water samples collected from selected springs and wells, (3) chemical analyses and calculated geothermometer temperatures of spring and well water samples in the literature, (4) thermal gradients measured in accessible wells, and (5) geology. The highest water temperature recorded in the St. George basin is 42/sup 0/C at Pah Tempe Hot Springs. Additional spring temperatures higher than 20/sup 0/C are at Veyo Hot Spring, Washington hot pot, and Green Spring. The warmest well water in the study area is 40/sup 0/C in Middleton Wash. Additional warm well water (higher than 24.5/sup 0/C) is present north of St. George, north of Washington, southeast of St. George, and in Dameron Valley. The majority of the Na-K-Ca calculated reservoir temperatures range between 30/sup 0/ and 50/sup 0/C. Anomalous geothermometer temperatures were calculated for water from Pah Tempe and a number of locations in St. George and vicinity. In addition to the known thermal areas of Pah Tempe and Veyo Hot Spring, an area north of Washington and St. George is delineated in this study to have possible low-temperature geothermal potential.
