Subsurface mapping from well points and 3D seismic interpretation are essential techniques used to study and locate structures in petroleum exploration. In this study, subsurface structure maps, detailed well log facies analysis, 3D seismic interpretation, and attribute analysis were used to map a Mississippian interval and middle Pennsylvanian age interval from two oil fields in Ness County, Kansas. The objective of this study is to analyze formation properties and facies distribution, map middle Pennsylvanian Cherokee channel deposits using seismic data, and to construct a structural model highlighting important features effecting oil production. Results show that the stratigraphic succession of this Mississippian interval consists of five main lithofacies: a siliceous facies, siliceous-calcitic facies, siliceous-dolomitic facies, carbonaceous facies, and a “mixed” facies. The siliceous facies is the dominant hydrocarbon reservoir unit in the area. Structural analysis and interpretation show two anticlinal structures associated with faulting on the western portion of the study area. These faults are known to have been caused by deformation associated with the Central Kansas Uplift. Two channels were mapped with one channel showing six possible compartments associated with differences in reservoir characteristics. The importance of identifying compartments in the reservoir is that they are associated with permeability changes and hydrocarbon production. These results show that an integrated approach using geologic and seismic analysis can be more effective than structural contour maps in mapping subtle structural and stratigraphic features in Mid-Continent hydrocarbon reservoirs.
