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.

In response to a need for a concise presentation of new terms and concepts in salt tectonics, we have compiled a glossary that focuses on ideas developed during the 1980's.

The Upper Devonian Woodford Formation is an organic-rich petroleum source rock that extends throughout West Texas and southeastern New Mexico and currently is generating oil or gas in the subsurface.

In mature sedimentary basins, where mechanical compaction is negligible, the hydrodynamics is typically described by steady-state flow driven by potential energy represented by the water table, which generally follows the topography.

Unrecovered mobile oil is oil that is movable at reservoir conditions but is prevented from migrating to existing we1 l bores because of geologic complexities or heterogeneities.
