Abstract
In this area of more than 42,800 square miles more than 2,615,653,966 barrels of oil have been produced from Paleozoic rocks. Sandstone, conglomerate, and carbonate reservoirs have oil and gas accumulations in both stratigraphic and structural traps. Cambrian, Ordovician, Silurian, Devonian, Mississippian, Pennsylvanian, and Permian rocks reaching a total maximum thickness of about 19,000 feet prevail in the area. Pennsylvanian and Permian strata contain remarkable carbonate reefs of various kinds which if completely encased in shale form excellent oil and gas traps. Major structural features include the Bend arch, Electra arch, Muenster arch, Fort Worth basin, Baylor basin, Fort Chadburne fault zone, Concho arch, and End_Page 123------------------------------ the buried Ouachita Mountain overthrust belt. Gently dipping surface strata of Permian, Pennsylvanian, and Cretaceous rocks mask most of the deep subsurface structure. End_of_Article - Last_Page 124------------
