Arbuckle Reservoirs in Central Kansas: Relative Importance of Depositional Facies, Early Diagenesis and Unconformity Karst Processes on Reservoir Properties |

Cored intervals were compared with wire-line log response (e.g., gamma-ray, neutron, and density logs) to identify possible flooding surfaces. This analysis suggests that the bases of many thin shale beds, shaly beds mixed with carbonate mudstone, and intraformational conglomerates with shaly to carbonate mud-rich matrixes are probable flooding surfaces. These beds are potential reservoir seals. For example, unit 10 in most cores from central Rice County, contains abundant moldic and oomoldic packstones. These reservoir facies are overlain by thin shaly beds.
