Factors Necessary to Define a Pressure Seal
A pressure seal is a rock layer capable of confining anomalous pressure over geologic time. In general, three factors are necessary to define a pressure seal: time, thickness, and permeability. TheExpand

Application of bottom-hole temperature corrections in geothermal studies
Abstract Bottom-hole temperature (BHT) data measured in oil and gas wells constitute a large, low quality set of temperature observations commonly used in geothermal studies. Raw BHT data are, on theExpand

Heat flow and thermal history of the Anadarko Basin and the western Oklahoma Platform
Abstract The average geothermal gradient in the Anadarko Basin and the Oklahoma Platform estimated from 856 corrected bottom-hole temperatures (BHTs) is 21°C/km. Analysis of previously publishedExpand

Regional permeability estimates from investigations of coupled heat and groundwater flow, north slope of alaska
Earlier studies of terrestrial heat flow in the North Slope Basin, Alaska, found that heat flow varies systematically in a trend perpendicular to the strike of basin strata and the neighboring BrooksExpand
