Abstract The Texas and Oklahoma Panhandle areas encompass a vast area of stratigraphic and structural entrapment for gas and oil, principally gas. Significant reserves and production have been found continuously since 1918 and there should be no decrease in activity in the foreseeable future. The Anadarko basin, defined on the south by the buried Amarillo mountains and on the west by the Cimarron uplift, and rising into the shallow Hugoton embayment on the north, received a flood of sediments in the Pennsylvanian which provided the principal reservoir rocks. Morrow, Virgil, and Missouri rocks are the most important producing units.
