Regional Geology of the Low-Permeability, Gas-Bearing Cleveland Formation,Western Anadarko Basin, Texas Panhandle: Lithologic and Depositional Facies, Structure, and Sequence Stratigraphy. Topical Report, January 1989-December 1991

摘要

The Upper Pennsylvanian (lower Missourian) Cleveland Formation produces gas fromlow-permeability ('tight') sandstone reservoirs in the western Anadarko Basin of the northeastern Texas Panhandle. In the six-county region, these reservoirs had produced more than 412 Bcf of natural gas through December 31, 1989. Because of their typically low permeability, the Cleveland sandstones require acidizing and hydraulic fracture treatment to produce gas at economic rates. Since 1982 the Gas Research Institute has supported geological investigations throughout the United States to develop the scientific and technological knowledge for producing from low-permeability, gas-bearing sandstones. As part of the program and the GRI Tight Gas Sands project, the Bureau of Economic Geology has been conducting research on low-permeability sandstones in the Cleveland Formation and on several other sandstone units of similar character in Texas and Wyoming.
