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

Hot dry rock fracture propagation and reservoir characterization

Description: North America's largest hydraulic fracturing opeations have been conducted at Fenton hill, New mexico to creae hot dry rock geothermal reservoirs. Microearthquakes induced by these fracturing operations were measured with geophones. The large volume of rock over which the microearthquakes were distributed indicates a mechanism of hydraulic stimulation which is at odds with conventional fracturing theory, which predicts failure along a plane which is perpendicular to the least compressive earth … more

Numerical simulation of ground-water flow in the Culebra dolomite at the Waste Isolation Pilot Plant (WIPP) site: Second interim report

Description: This hydrogeologic modeling study has been performed as part of the regional hydrologic characterization of the Waste Isolation Pilot Plant (WIPP) Site in southeastern New Mexico. The study resulted in an estimation of the transmissivity distrubution, hydraulic potentials, flow field, and fluid densities in the Culebra Dolomite Member of the Permian Rustler Formation at the WIPP site. The three-dimensional finite-difference code SWIFT-II was employed for the numerical modeling, using variable-f… more

Televiewer measurement of in-situ stress direction at the Fenton Hill Hot Dry Rock Site, New Mexico

Description: The in situ stresses at Fenton Hill has been determined in drill hole EE-3A by observations of wellbore breakouts on imagery obtained with a televiewer logging tool. Wellbore shape, tool offcentering, and tool misalignment cause geometric distortions which have been treated by comparing imagery from two logging runs made six months apart. The comparison establishes that wellbore degradation in drill hole EE-3A is due to breakouts, which grow larger with time. The azimuth of the axis of minimum … more

Hydrostatic pressure and fluid-density distribution of the Culebra Dolomite member of the Rustler Formation near the Waste Isolation Pilot Plant, southeastern New Mexico

Description: The primary objectives of the Pressure - Density Survey were to obtain the middle-of-formation pressures, determine well-bore fluid densities, define well-bore fluid density stratification, and to provide, where possible, formation water density values for wells where little or no information on densities exists. The survey collected ground-water pressure and density data during three field testing periods during the years 1986 and 1987. Data were collected from 33 individual wells located in t… more
