This nontechnical guidebook describes seven trails that visitors can walk within Pedernales (Spanish for the "flint" found in the park area) State Park, near Johnson City, in the Hill Country of Texas.

From 1952 to 1956, Pemex conducted a considerable amount of stratigraphic field work in the eastern Sierra Madre and in Laramide folds to the north across the Sabinas Basin.

We classify salt-related faults and fault welds in the northern Gulf of Mexico on the basis of the three-dimensional geometry of the faults, welds, deformed strata, and associated salt bodies.

Use of groundwater-flow models for prediction of future availability of water resources is standard practice. Having accurate hydraulic parameters for input into groundwater-flow models is critical to the generation of realistic local and regional water-resource management plans.

Oil and gas resources on University Lands, 2.1 million acres in 19 West Texas counties, constitute a major asset of the University of Texas System. The original oil in place (OOIP) of the 102 major University Lands oil reservoirs is calculated to be 7,520 MMbbl.

"When in the early 1980’s it became known that the Federal Government was planning to undertake the construction of the massive Superconducting Super Collider (SSC) project, scientists in the various states, still without precise information on the criteria to be established for site selection, b

This color poster depicts the rock-fabric method for linking geologic descriptions with petrophysical properties.

Salt structures can be extremely challenging to interpret and understand. To begin with, the high velocity contrast between salt and most sedimentary rocks means that many salt structures are poorly imaged on seismic data.
