Title: Cunningham Field, Kingman and Pratt Counties, Kansas

Author(s): Richard B. Rutledge, Howard S. Bryant (2)


The discovery well, drilled in the NE. cor. of Sec. 30, T. 27 S., R 10 W., to test core-drill structure, found production at 3,360-3,468 feet in the Pennsylvanian Lansing limestone--"Oswald pay"--of western Kansas. Gradual development has resulted in 33 Lansing wells, one Ordovician gas well, one Permian gas well, and two Ordovician dry holes.

The Lansing pay horizons are numerous and variable thin porous streaks, many oolitic, in the upper 110 feet of that limestone formation. The Ordovician gas horizons are the cherty Viola dolomitic limestone, the sands of the upper Simpson and the "Siliceous lime." Oil is present in the "Siliceous lime" below the gas.

The structure had its beginning in post-Mississippian and pre-Marmaton deformation, and its growth continued at intervals in Pennsylvanian and Permian time. It shows increasing steepness and westward shifting with depth.

Production data and production practices are discussed.
