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.

This large, 4-sheet geologic map displays more than 350 lithostratigraphic units ranging in age from Precambrian to Quaternary.

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.
