Woodford Shale in Portions of Logan County, Oklahoma: Feasibility of Defining an Algorithm for Mapping and Exploration

Abstract

The purpose of this study was to examine the well-log character of the Woodford Shale in portions of Logan Co., Oklahoma and define an algorithm for mapping the unit. Well-logs were examined. Structural geologic maps and isopach maps were created, based on the well-log data. Relationships among the well-logs were studied and cataloged. Variation within the Woodford Shale was determined, to give information concerning the structure and topography of the units bounding the formation. Defining categories for the types and characters of the Woodford stratagraphic boundaries allowed a methodology be derived to make mapping the unit more effective in the search for reservoirs and traps.
