Geology And Engineering Characteristics Of Selected Low Permeability Gas Sandstones PDF Download

Geologic and engineering data for selected low permeability gas formations were compiled to provide a basis for selecting potential sites for the Gas Research Institute's (GRI) fourth Staged Field Experiment (SFE) and cooperative wells with industry. Increasingly detailed screening criteria were applied to 189 documented tight gas settings to designate twelve candidate formations for field research. Technical selection criteria were established to ensure that resulting field research addressed the resource potential of a formation, recognized scientific challenges to be overcome, and maximized opportunities for technology transfer. Four formations are in the Rocky Mountains (Frontier, Mancos "B", Corcoran-Cozzette, Mesaverda), two in the Appalachian Basin (Clinton-Medina, Berea), two in the Denver Basin (Codell, Niobrara), and one each in the San Juan (Pictured Cliffs), Permian (Abo), Anadarko (Cleveland), and Texas Gulf Coast (Wilcox) basins. The formations represent a range of current development and technical challenges. Four of the twelve formations were identified as having highest potential: the Abo, Corcoran-Cozzette/Mesaverde, Frontier and Cleveland.
