RESERVOIR CHARACTERIZATION OF THE KIZLER NORTH FIELD, LYON CO., KANSAS, USA

The Kizler North Field is located near the western flank of the Forest City Basin in Kansas, USA. The basin is a Paleozoic anticlinal structural and topographic basin which came into existence Mississippian. Reservoirs range in age from Ordovician to Middle Pennsylvanian. The purpose of this study is to correlate 2D seismic data with well data to visualize structures, to detect stratigraphic features and to describe seismic facies and reflection patterns of the target horizons. Seismic structural interpretation indicates seven major faults, which may play an important role in oil migration and some structural highs for possible oil traps. The reservoirs are related to a structural closure associated with wrench fault system and reservoir dolomitization. The wrench fault systems of this field are difficult to locate but very prolific. The oil-bearing reservoirs are: the Middle Pennsylvanian Bartlesville shoestring sand in the Middle Pennsylvanian Cherokee Shale, the Mississippian Osagian Series, the Late Devonian Hunton Limestone, and the Ordovician Viola Limestone and Simpson Group.
