Exploration for Petroleum in Cyclic Sediments of Late Pennsylvanian Age in Central and Western Kansas: A Closer Look at a Mature Province

W. Lynn Watney

Abstract

Upper Pennsylvanian, Lansing and Kansas City Groups of western and central Kansas offer continued opportunity for new oil discoveries. Selective isopachs construction and facies mapping keyed with core descriptions of individual Lansing and Kansas City cycles provides the necessary information to interpret general environmental conditions active during the deposition of a cycle across the shelf. Quality of potential reservoir carbonates varies in response to the duration and extent of: 1) energy levels in the water column affecting deposition of regressive carbonate and 2) early diagenesis responsible for the formation of secondary porosity.

The western Kansas shelf is divided into several settings of carbonate reservoir types distinguished on the basis of the mapping results. A relative risk factor for exporation success is assigned to each area.
