The UGCenter’s new Special Report on the Arkoma Basin provides an in-depth look at the petroleum-rich region spanning southeastern Oklahoma and west-central Arkansas.
According to a U.S. Geological Survey conducted in 2010, the estimated mean volume of the basin is 38 trillion cubic feet of undiscovered natural gas, 159 million barrels of NGL, and no oil in accumulations of 0.5 million barrels or larger in the Arkoma Basin Province and related areas. More than 97% of the undiscovered gas occurs in continuous accumulations—70% in shale gas formations, 18% in a basin-centered accumulation with tight sandstone reservoirs, and 9% in coal beds. Less than 3% of the natural gas occurs in conventional accumulations.
The Arkoma Basin contains Upper Cambrian–Lower Pennsylvanian strata, deposited on the shelf of a passive margin, overlain by Lower–Middle Pennsylvanian foreland-basin deposits. Producing formations include Caney Shale, Woodford Shale, Moorefield Shale and Fayetteville Shale. The Devonian Woodford Shale generally ranges from 100 ft to 220 ft thick at depths of 6,000 ft to 11,000 ft in Oklahoma.
