The Atlas of Major Central and Eastern Gulf Coast Gas Reservoirs is the second in a series compiling geologic and engineering data on natural gas reservoirs in the major gas-producing regions of the United States.

The 37-Ma-old Infiernito caldera of the northern Chinati Mountains is a major eruptive center of the mid-Tertiary volcanic field of Trans-Pecos Texas. Volcanism in the Chinati Mountains began with eruption of a sequence of rhyolitic to trachytic lavas, the precollapse lavas.

Chemical and physical approaches are used to study unsaturated flow; however, few studies include an in-depth analysis of data from both approaches.

A waterflood was begun in 1985 in Taylor-Link West San Andres unit (10 million barrels cumulative production) on the south margin of the Central Basin Platform to capture a remaining mobile oil target estimated at 20 million barrels.

Grabens overlying diapirs have previously been ascribed to intrusion, withdrawal, or dissolution of salt. We propose, however, that many grabens or half grabens above diapirs form by regional thin-skinned extension of a brittle overburden.

Texas has large resources of oil and natural gas that remain unrecovered.

The Plio-Pleistocene hydrocarbon fairway of offshore western Louisiana is restricted to the outer continental shelf and upper continental slope where a thick wedge of nearshore and deep-marine sediments was deposited.

Since 1979, the U.S. Geological Survey (USGS) has funded cooperative programs with coal-bearing states in an effort to provide current U.S. coal resource estimates that are calculated by uniform, computerized methods.

The Hueco Bolson is a segment of the Rio Grande Rift that formed as a result of late Tertiary Basin and Range deformation. The upper Tertiary Fort Hancock Formation and the upper Tertiary-Quaternary Camp Rice Formation compose the basin fill except in the deepest (western) parts of the bolson.
