Summary Production Information

Field Size: 640 acres

Productive Oil Wells: 3 as of April 2025
Abandoned Wells: 7
Cumulative Oil: 219,826.30 bbls as of April 2025

Producing Formation:


LANS.-K.C.
(Lansing - Kansas City Supergroup)
Depth Top: 4056 feet
Formation Lithology: Fine to medium crystalline fossiliferous limestone with fossil-cast and vugular porosity.
Trap Type: Producing from a 240-foot zone in the Kansas City formation, which is part of the Pennsylvanian System. Accumulation is controlled by a small NE - SW anticline with 10 feet of closure. A minor flexure developed on a broader positive area extending from Barton County to the southwest through Stafford, Pratt and Barber Counties. Located locally on a producing trend established by the Iuka Field to the northeast and subsequently extended by the Southwest Fitzsimmons Pool, which produces from the Simpson Formation.
