The Delaware Basin is the larger of the two major lobes of the Permian Basin within the foreland of the Ouachita–Marathon thrust belt separated by the Central Basin Platform. The basin contains sediment dating to Pennsylvanian , Wolfcampian ( Neal Ranch and Lenox Hills Formations [ 7 ] ), Leonardian ( Avalon Shale ), and early Guadalupian times.
This is the first assessment of continuous resources in the Wolfcamp shale in the Midland Basin portion of the Permian. [9] During the 1980s, vertical wells produced oil in the Wolfcamp area. [ 10 ] However, since 2000 in North America, horizontal drilling or porpoising along with hydraulic fracturing have grown tremendously and are tapping the ...
The significance of the region to Texas' overall production, however, has been tempered by the increase of drilling activity in the Eagle Ford Shale and the Permian Basin. [ 15 ] Since its discovery, the East Texas Oil Field has produced more than 5.2 billion barrels (830,000,000 m 3 ) of oil, and it originally contained more than 7 billion ...
The Kupferschiefer is a regional stratigraphic unit stretching across an area of 600,000 square kilometres (230,000 sq mi) in the Southern Permian Basin of north-central Europe. The unit is typically 30 to 60 centimetres (12 to 24 in) thick.
Permian Basin is in geology the name of two large intercontinental basins that were formed in the Permian period, neither of which are in Perm Krai: Permian Basin (North America) , a basin in the subsurface of the south of the United States, in west Texas and southeast New Mexico
The Delaware Basin is a geologic depositional and structural basin in West Texas and southern New Mexico, famous for holding large oil fields and for a fossilized reef exposed at the surface. Guadalupe Mountains National Park and Carlsbad Caverns National Park protect part of the basin.
Within the basin the formation consists of a basal phosphorite overlain by a thick sequence of chert and cherty sandstone. To the east in western Wyoming the Phosphoria gradually decreases in thickness and is intertongued with carbonate rocks of the Park City Formation and redbed sandstones of the Chugwater Formation of Permian to Triassic age.

The total thickness is about 1,000 meters (3,300 ft). The base of the formation is largely concealed in the subsurface, and the formation is overlain by the Cutoff Shale. [1] The formation grades laterally into the Victorio Peak Formation. [3] The uppermost shale beds of the formation have been assigned to the Avalon Shale. [4]
