Characterization of bedded salt for storage caverns -- a case study from the Midland Basin, Texas Characterization of bedded salt for storage caverns -- a case study from the Midland Basin, Texas 2000

The geometry of Permian bedded salt in the Midland Basin is a product of the interaction between depositional facies and postdepositional modification by salt dissolution.

Permeability structure of the Edwards aquifer, south Texas -- implications for aquifer management Permeability structure of the Edwards aquifer, south Texas -- implications for aquifer management 1998

This report describes the three-dimensional distribution of hydraulic conductivity in the Edwards aquifer from Kinney to Comal Counties, Texas.

Facies and diagenesis of the Austin Chalk and controls on fracture intensity -- a case study from north-central Texas Facies and diagenesis of the Austin Chalk and controls on fracture intensity -- a case study from north-central Texas 1998

The urban corridors associated with the Dallas, Austin, and San Antonio metropolitan areas lie on Austin Chalk outcrop. In these areas of rapid urbanization, ground-water information is needed to resolve environmental issues. The Austin Chalk also produces hydrocarbons in the deep subsurface.

Edwards aquifer ground-water resources: geologic controls on porosity development in platform carbonates, south Texas Edwards aquifer ground-water resources: geologic controls on porosity development in platform carbonates, south Texas 1996

Focusing on the highly developed Edwards aquifer, which supplies water for a large area of south-central Texas, this report presents a three-dimensional model of the porosity distribution in the aquifer, which quantifies the spatial distribution of water resources and provides information that ca

Origin and development of playa basins, sources of recharge to the Ogallala aquifer, southern High Plains, Texas and New Mexico Origin and development of playa basins, sources of recharge to the Ogallala aquifer, southern High Plains, Texas and New Mexico 1995

More than 20,000 playa basins have formed on the Southern High Plains of Texas and New Mexico.

Chert reservoir development in the Devonian Thirtyone Formation: Three Bar field, West Texas Chert reservoir development in the Devonian Thirtyone Formation: Three Bar field, West Texas 1995

Chert reservoirs of the Lower Devonian Thirtyone Formation represent a substantial part of the hydrocarbon resource in the Permian Basin. More than 700 million barrels of oil has been produced from these rocks, and an equivalent amount of mobile oil remains.
