Open-file Report 2003-30

Setting and History

The Panoma Field (2.9 TCF gas) produces from Permian Council Grove Group marine carbonates and nonmarine silicilastics in the Hugoton embayment of the Anadarko Basin. It and the Hugoton Field, which has produced from the Chase Group since 1928, the top of which is 300 feet shallower have combined to produce 27 TCF gas, making it the largest gas producing area in North America. Both fields are stratigraphic traps with their updip west and northwest limits nearly coincident. Maximum recoveries in the Panoma are attained west of center of the field. Deeper production includes oil and gas from Pennsylvanian Lansing-Kansas City, Marmaton, and Morrow and the Mississippian.
