Uranium potential of southwestern New Mexico (southern Hidalgo County), including observations on crystallization history of lavas and ash tuffs and the release of uranium from them. Final report

Description: Geological environments present in southwestern New Mexico include thick sequences of sedimentary rock including limestone, conglomerates, sandstone, and shale: igneous intrusions with associated metal deposits; caldera centers, margins, and outflow facies; and basins with marginal faults and thick late Cenozoic sedimentary fillings. Predominant rock types are Paleozoic carbonates, Mesozoic terrigeneous rocks and carbonates, and Cenozoic volcanic rocks and basin-filling terrigeneous rocks. Cons… more

Drilling rate changes when air drilling is switched to mist drilling. [Claystone]

Description: Eight shallow (30-foot-deep) holes were drilled in four formations to determine if the reduction in penetration rate that usually occurs when air drilling is changed to mist drilling might be due to the physical action of drilling a wet, soapy rock. The results showed an average loss of 9.3%, with the greatest loss occurring in limestone. The softest formation (claystone) showed only a 1.2% reduction in penetration rate; the two sandstones averaged 10.0-percent loss; and the limestone showed a … more

Strontium Isotopic Composition of Paleozoic Carbonate Rocks in the Nevada Test Site Vicinity, Clark, Lincoln, and Nye Counties, Nevada and Inyo County, California.

Description: Ground water moving through permeable Paleozoic carbonate rocks represents the most likely pathway for migration of radioactive contaminants from nuclear weapons testing at the Nevada Test Site, Nye County, Nevada. The strontium isotopic composition (87Sr/86Sr) of ground water offers a useful means of testing hydrochemical models of regional flow involving advection and reaction. However, reaction models require knowledge of 87Sr/86Sr data for carbonate rock in the Nevada Test Site vicinity, wh… more

Assessment of potential radionuclide transport in site-specific geologic formations

Description: Associated with the development of deep, geologic repositories for nuclear waste isolation is a need for safety assessments of the potential for nuclide migration. Frequently used in estimating migration rates is a parameter generally known as a distribution coefficient, K/sub d/, which describes the distribution of a radionuclide between a solid (rock) and a liquid (groundwater) phase. This report is intended to emphasize that the use of K/sub d/ must be coupled with a knowledge of the geology… more

Underground nuclear explosions at Astrakhan, USSR

Description: The three underground nuclear explosions recorded in 1980 and 1981 by Hagfors Observatory in Sweden are in the vicinity of Astrakhan on the Caspian Sea. They are believed to be associated with the development of a gas condensate field discovered in 1973. The gas producing horizons are in limestones at 4000 m depth. They are overlain by bedded, Kungarian salts. Salt domes are recognized in the area. Plans to develop the field are contained in the 11th Five Year Plan (1981-82). The USSR has solic… more

Effective-stress-law behavior of Austin chalk rocks for deformation and fracture conductivity

Description: Austin chalk core has been tested to determine the effective law for deformation of the matrix material and the stress-sensitive conductivity of the natural fractures. For deformation behavior, two samples provided data on the variations of the poroelastic parameter, {alpha}, for Austin chalk, giving values around 0.4. The effective-stress-law behavior of a Saratoga limestone sample was also measured for the purpose of obtaining a comparison with a somewhat more porous carbonate rock. {alpha} f… more

Using power series expansions of moduli to interpolate between release curves from dynamic tests: Technique and application

Description: Recently an appreciable number of continuous release profiles have been measured from dynamic experiments with geological materials. For each material an empirical generalization of the available release curves may be constructed to allow easy application of the experimental data to problems in much the same way as a linear shock velocity -- particle velocity fit allows easy application of Hugoniot data. This generalization is made in two steps. The first is to compute the Eulerian axial modulu… more

Seismic and Rock Physics Diagnostics of Multiscale Reservoir Textures

Description: As part of our study on ''Relationships between seismic properties and rock microstructure'', we have continued our work on analyzing well logs and microstructural constraints on seismic signatures. We report results of three studies in this report. The first one deals with fractures and faults that provide the primary control on the underground fluid flow through low permeability massive carbonate rocks. Fault cores often represent lower transmissibility whereas the surrounding damaged rocks a… more

Evaluation of Dust Cake Filtration at High Temperature with Effluence from an Atmospheric Fluidized-bed Combustor

Description: In the spring of 1989, two separate test series were simultaneously conducted at the US Department of Energy's (DOE's) Morgantown Energy Technology Center (METC) to examine applied and fundamental behavior of dust cake filtration under high temperature and high pressure (HTHP) conditions. The purpose was to provide information on dust-cake filtration properties to gas stream cleanup researchers associated with the Tidd 70 megawatt (MW) pressurized fluidized-bed combustor (PFBC). The two test fa… more

Regional hydrology of the Dixie Valley geothermal field, Nevada: preliminary interpretations of chemical and isotopic data

Description: Chemical and isotopic analyses of Dixie Valley regional waters indicate several distinct groups ranging in recharge age from Pleistocene (<20 ka) to recent (<50a). Valley groundwater is older than water from perennial springs and artesian wells in adjacent ranges, with Clan Alpine range (east) much younger (most <50a) than Stillwater range (west; most >1000a). Geothermal field fluids ({approximately}12-14 ka) appear derived from water similar in composition to non-thermal groundwate… more

Gravity and magnetic study of the Pahute Mesa and Oasis Valley region, Nye County, Nevada

Description: Regional gravity and aeromagnetic maps reveal the existence of deep basins underlying much of the southwestern Nevada volcanic field, approximately 150 km northwest of Las Vegas. These maps also indicate the presence of prominent features (geophysical lineaments) within and beneath the basin fill. Detailed gravity surveys were conducted in order to characterize the nature of the basin boundaries, delineate additional subsurface features, and evaluate their possible influence on the movement of … more

Increased Oil Production and Reserves Utilizing Secondary/Tertiary Recovery Techniques on Small Reservoirs in the Paradox Basin, Utah, Annual Report: 1996-1997

Description: The Paradox basin of Utah, Colorado, and Arizona contains nearly 100 small oil fields producing from carbonate buildups or mounds within the Pennsylvanian (Desmoinesian) Paradox Formation. These fields typically have one to four wells with primary production ranging from 700,000 to 2,000,000 barrels of oil per field at a 15 to 20% recovery rate. At least 200 million barrels of oil is at risk of being unrecovered in these small fields because of inefficient recovery practices and undrained heter… more
