Title Publication Year Abstract Author Series Publisher
Structural cross sections, Miocene series, Texas continental shelf Structural cross sections, Miocene series, Texas continental shelf 1985

These cross sections numerically correspond to previously published onshore cross sections (CS0002--Dodge and Posey, 1981) and extend those sections across the continental shelf into the Miocene, a recent target of renewed petroleum exploration.

Structural cross sections, Plio-Pleistocene series, southeastern Texas Structural cross sections, Plio-Pleistocene series, southeastern Texas 1989

These cross sections illustrate the regional structure and stratigraphy beneath the Texas continental shelf .

Depositional history, facies analysis, and production characteristics of hydrocarbon-bearing sediments, offshore Texas Depositional history, facies analysis, and production characteristics of hydrocarbon-bearing sediments, offshore Texas 1985

Large areas of offshore Texas remain unexplored even though sedimentary facies and structural traps favor the generation and accumulation of hydrocarbons.

Factors controlling reservoir quality in Tertiary sandstones and their significance to geopressured geothermal production Factors controlling reservoir quality in Tertiary sandstones and their significance to geopressured geothermal production 1981

Variable intensity of diagenesis is the factor primarily responsible for contrasting regional reservoir quality of Tertiary sandstones from the upper and lower Texas coast.

Lower Miocene (Fleming) depositional episode of the Texas coastal plain and continental shelf:  structural framework, facies, and hydrocarbon resources Lower Miocene (Fleming) depositional episode of the Texas coastal plain and continental shelf: structural framework, facies, and hydrocarbon resources 1986

The Fleming Group and its basinward equivalents constitute the stratigraphic record of one of the major Cenozoic depositional episodes of the northern Gulf Coast Basin. The depositional sequence representing the episode is bounded above by the Amphistegina B shale and below by the Anahuac shale.

Middle-Upper Miocene depositional sequences of the Texas coastal plain and continental shelf:  geologic framework, sedimentary facies, and hydrocarbon plays Middle-Upper Miocene depositional sequences of the Texas coastal plain and continental shelf: geologic framework, sedimentary facies, and hydrocarbon plays 1988

Middle-upper Miocene depositional sequences of offshore Texas represent the last regionally significant influx of terrigenous elastic sediments into the western Gulf Coast Basin.

Plio-Pleistocene depositional sequences of the southeastern Texas continental shelf and slope:  geologic framework, sedimentary facies, and hydrocarbon distribution Plio-Pleistocene depositional sequences of the southeastern Texas continental shelf and slope: geologic framework, sedimentary facies, and hydrocarbon distribution 1991

Plio-Pleistocene strata of offshore Texas having hydrocarbon exploration potential are restricted to the southeastern continental shelf and upper continental slope. This thick wedge of nearshore and deep-marine sediments firms the west margin of a late Neogene and Quaternary depocenter.
