Six interlocking regional stratigraphic cross sections of Lower Cretaceous strata (middle Albian-lower Cenomanian) of the Edwards and Stockton Plateaus of West Texas illustrate the vertical and lateral extent of lithostratigraphic units and distribution of facies and facies tracts.

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.

Sulfur, along with salt, coal, and limestone, is one of the basic raw materials of the chemical industry. A nation’s per capita sulfur consumption is a reliable index to its chemical production and a rough index to its standard of living.

Reexploration of old fields in mature hydrocarbon provinces, such as the Permian Basin of West Texas and New Mexico, may significantly increase known oil and gas reserves.

Surface fissures have been observed in many desert basins in the western United States. These surface-collapse features are usually discovered after a normally dry surface has been covered with water, either by runoff from intense rainfall, by flooding, or by irrigation.

A multidisciplinary reservoir-characterization study of the Ellenburger Group was conducted over a 176-mi2 3-D seismic grid in Pecos, Reeves, and Ward Counties in the southern Delaware Basin of West Texas.

Tertiary rocks, including sandstone, conglomerate, shale, pyroclastics, tuff, and lava, are preserved in Big Bend National Park and in a much larger area to the west and northwest. Some of the rocks have distinctive characteristics that enable recognition by their lithology.

The Permian Spraberry Trend, once regarded as the world's largest uneconomic oil field, is a prime candidate for reserve growth through extended conventional recovery.
