The Rellim oil field in Rice County, Kansas, has produced some 800,000 bbls of oil from a productive area of 1,200 acres with 21 productive wells. Key production horizons are limestone of the Mississippian Osage group and the Hertha Limestone of the Pennsylvanian Kansas City Group. The Osage group pinches out updip against the pre-Pennsylvanian unconformity, forming a trap in sec. 3, T. 19 S., R. 6 W. Limestones of the Lansing and Kansas City Groups are draped over folds or the karsted surface of the pre-Pennsylvanian unconformity forming traps. The study was conducted using only information in the public domain. Oil saturation ranged as high as 45% in the Hertha reservoir. Possible future activities in the area to increase production include waterflooding the Hertha Limestone reservoir and mapping the Mississippian pinchout with additional subsurface data and 3-D seismic to identify attractive targets for extending the field.
