Lowstand valley fill and shelf-edge deltaic deposits in the Tannehill sandstone (Wolfcampian Cisco Group) in the Eastern Shelf of the Permian Basin are major targets for oil and gas exploration.

The Permian Basin of Texas and New Mexico is an important petroleum province with a complex tectonic history. This region has been shaped by several divergent and convergent deformation events since the Proterozoic Eon.

This is Volume 2 of a two-volume set. The set is the first comprehensive analysis of the Permian Basin in more than 60 years. Collectively, these chapters provide a spectrum of data and interpretations that characterize one of the largest hydrocarbon-producing super basins in the world.

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.

The Leonardian Spraberry Formation is a major oil-producing formation of the Permian Basin, accounting for more than 700 million barrels of oil produced from heterogeneous submarine-fan reservoirs.

Shallow-water-platform carbonate reservoirs of Permian age have accounted for more than half of the oil production in the Permian Basin, one of the largest oil-producing regions in the United States.

Silurian and Devonian carbonate and chert rocks in the Permian Basin constitute a prolific hydrocarbon-bearing succession in West Texas and New Mexico.
