Upper Pensylvanian and lower Permian rocks of the Eastern Shelf in North-central Texas are composed of 10 to 15 repetitive sequences including open shelf, deltaic, fluvial, and interdeltaic depositional systems.

To recover gas remaining in solution, large volumes of brine must be produced from watered-out gas reservoirs in the Gulf Coast.

A study of Gum Hollow delta, a modern fan delta along the north shore of Nueces Bay, Texas, was undertaken to determine the mechanics of fan development and the relationships between sedimentary processes and structures.

Cores and supporting petrophysical data from 20 wells in McAllen Ranch field were analyzed.

Facies architecture, structure, and diagenesis control reservoir geometry and distribution of remaining oil in shoreface, fluvial, and deltaic reservoirs of Miocene age in the 18-mi2 (46.7-km2) Mioceno Norte Area in northern Lake Maracaibo.

Upper Miocene and Pliocene shoreface and wave-dominated deltaic depocenters in the Macuspana Basin are related primarily to deep-sealed growth faults and large-scale rollover structures associated with shale evacuation.
