Porous and permeable strata of the Deep-Basin Brine aquifer underlie bedded evaporites that are being considered as repositories for high-level nuclear waste isolation in the Palo Duro Basin, Texas Panhandle. Formation-water samples collected from four U.S.
Permian strata in the Palo Duro Basin consist of multicyclic sequences of carbonate, nodular and laminated anhydrite, bedded halite, chaotic mudstone-halite, and terrigenous clastic sediments.
Lineament analysis was used to study the relationship between subsurface structure and surficial features in East Texas, southeastern Oklahoma, southwestern Arkansas, and northwestern Louisiana-areas of low topographic relief, moderate vegetation cover, and diverse land use.
San Andres and Grayburg reservoirs have yielded about 42 percent (9.8 billion barrels) of the total cumulative production of oil from the Permian Basin of West Texas.
