Northern Arizona Basin Study (NABS), 1989

Description: An experiment was conducted to better understand a frequent layer of northwest winds found in the Northern Arizona region.

Soil attenuation of leachates from low-rank coal combustion wastes: a literature survey. [116 references]

Description: In parallel with pursuing the goal of increased utilization of low-rank solid fuels, the US Department of Energy is investigating various aspects associated with the disposal of coal-combustion solid wastes. Concern has been expressed relative to the potential hazards presented by leachates from fly ash, bottom ash and scrubber wastes. This is of particular interest in some regions where disposal areas overlap aquifer recharge regions. The western regions of the United States are characterized … more

Geologic evolution of the Jemez Mountains and their potential for future volcanic activity

Description: Geophysical and geochemical data and the geologic history of the Rio Grande rift and the vicinity of the Jemez Mountains are summarized to determine the probability of future volcanic activity in the Los Alamos, New Mexico area. The apparent cyclic nature of volcanism in the Jemez Mountains may be related to intermittent thermal inputs into the volcanic system beneath the region. The Jemez lineament, an alignment of late Cenozoic volcanic centers that crosses the rift near Los Alamos, has playe… more

Characterization of facies and permeability patterns in carbonate reservoirs based on outcrop analogs

Description: The primary objective of this research is to develop methods for better describing the three-dimensional geometry of carbonate reservoir flow units as related to conventional or enhanced recovery of oil. Detailed characterization of geologic facies and rock permeability in reservoir-scale outcrops of the Permian San Andres Formation in the Guadalupe Mountains of New Mexico will provide the key data base. To this end detailed sampling on grids using a portable core-plugging device was undertaken… more

Age and location of volcanic centers less than or equal to 3. 0 m. y. old in Arizona, New Mexico, and the Trans-Peco area of West Texas

Description: This map is one of a series of maps designed for hot dry rock geothermal assessment in Arizona, New Mexico, and the Trans-Peco area of the west Texas. The 3.0 m.y. cutoff age was selected because original heat has probably largely dissipated in older rocks. The location of volcanic centers is more important to geothermal resource assessment than the location of their associated volcanic rocks; however, ages have been determined for numerous flows far from their source. Therefore, the distributi… more

Economics of a conceptual 75 MW Hot Dry Rock geothermal electric power station

Description: Man-made, Hot Dry Rock (HDR) geothermal energy reservoirs have been investigated for over ten years. As early as 1977 a research-sized reservoir was created at a depth of 2.9 km near the Valles Caldera, a dormant volcanic complex in New Mexico, by connecting two wells with hydraulic fractures. Thermal power was generated at rates of up to 5 MW(t) and the reservoir was operated for nearly a year with a thermal drawdown less than 10/sup 0/C. A small 60kW(e) electrical generation unit using a bina… more

Salinity variations and chemical compositions of waters in the Frio Formation, Texas Gulf Coast. Annual report

Description: Waters produced from sandstone reservoirs of the deep Frio Formation exhibit spatial variations in chemical composition that roughly coincide with the major tectonic elements (Houston and Rio Grande Embayments, San Marcos Arch) and corresponding depositional systems (Houston and Norias deltas, Greta-Carancahua barrier/strandplain system) that were respectively active along the upper, lower, and middle Texas Coast during Frio deposition. Within an area, salinities are usually depth dependent, an… more

Reasons for the termination of, and DOE losses in, a geothermal demonstration powerplant project

Description: The 50-megawatt Baca geothermal demonstration powerplant project, located in northern New Mexico, was the Department of Energy's (DOE's) initial effort to demonstrate geothermal powerplant technology. The project, started in 1978, was believed to have a high probability of success, and its cost was to be shared equally with the industry participants. GAO's review showed that the project was terminated in January 1982 because sufficient geothermal steam to operate the powerplant could not be obt… more

Hydrothermal alteration in well Baca 22, Baca geothermal area, Valles Caldera, New Mexico

Description: A number of exploration wells were drilled to supply steam for a proposed electric generating plant. Drill cuttings from one of these wells, Baca 22, were studied with a petrographic microscope and by x-ray diffraction to determine the nature of the original rocks and of the hydrothermal alteration. The hydrothermal alteration is used to determine the temperatures of alteration which can then be compared with borehole temperatures to determine if the mineral assemblages are compatible with pres… more

Lithologic descriptions and temperature profiles of five wells in the southwestern Valles caldera region, New Mexico

Description: The subsurface stratigraphy and temperature profiles of the southern and western Valles caldera region have been well constrained with the use of data from the VC-1, AET-4, WC 23-4, PC-1 and PC-2 wells. Data from these wells indicate that thermal gradients west of the caldera margin are between 110 and 140)degrees)C/km, with a maximum gradient occurring in the bottom of PC-1 equal to 240)degrees)C/km as a result of thermal fluid flow. Gradients within the caldera reach a maximum of 350)degrees)… more
