Southern Oklahoma (Shallow Oil and Natural Gas)
The oil-rich area of southern Oklahoma includes three anticlinal systems; the Arbuckle Mountains,
Criner Hills, and Muenster Arch. Corresponding basinal systems include the Marietta, Ardmore, and Anadarko Basins.
Oil fields are abundant at basin-margins in traps produced by the Pennsylvanian Wichita and Arbuckle orogenies.
An extreme variety of traps characterize southern Oklahoma. The traps can be structural,
including normal and recumbent anticlines often associated with normal faults and thrust faults, or stratigraphic, being sand pinchouts
and reservoir subcrops under basal Pennsylvanian and Permian unconformities.
