Effect of stress on the microstructure of a graywacke sandstone from the site of the Rio Blanco gas-stimulation experiment
Project Rio Blanco was designed to increase rock permeability in an existing gas reservoir by fracturing the rock with a vertical array of three simultaneous nuclear explosions. The project site was CER Geonuclear hole RB-E- 01, Section 14, T35, R98W, Rio Blanco County, in the Piceance Creek Basin of northwest Colorado. The most essential part of this project was to produce fracturing in, and thereby to increase the permeability of, the reservoir rock. This report contains the results of optical and scanning electron microscope (SEM) studies done on unstressed and laboratory-stressed samples of graywacke sandstone from the 6458-ft level of the emplacement hole. Laboratory-stressed samples were from uniaxial-stress and uniaxial-strain tests made as part of equation-of-state measurements used to provide input parameters for preshot code calculations. (auth)

Reconnaissance heat flow and Geothermal gradient study in north central Owyhee county, Idaho
Temperature data were obtained in 41 wells, thermal conductivity in 12 wells, and published data were synthesized in order to investigate the geothermal character of an area in northern Owyhee County, Idaho. This area includes the Bruneau and Grand View-Castle Creek KGRA's and is characterized by a large number of warm water artesian irrigation wells. In the Oreana-Grand View areas the geothermal gradient to 3000 feet is 4.0 {+-} 1 F/100 ft and the heat flow is about 2.1 {+-} .2 HFU (about normal for the western US). The southern part of the Oreana area along the upper part of Castle Creek and the Little Valley-Bruneau areas have geothermal gradients ranging from 5 to 8 F/100 ft and heat flow values from 50% to 100% above the regional average. Part of the Murphy area has a geothermal gradient of about 4.0 F/100 ft and normal heat flow while the other part has gradients of 6 to 10 F/100 ft and above-regional heat flow. The high values may be directly or indirectly (via geothermal systems) associated with shallow magmatic heat sources, or with regional ground water flow. If local magmatic heat sources are present they may occur along the southern hingeline …
