 The Wolfcampian marine sediments include an arkosic lime, an arkosic dolomite, the Moore County Limestone, the White Dolomite, and the Brown Dolomite.The Leonardian Panhandle Lime, or Wichita, and Red Cave overlay these Wolfcampian sediments, with the anhydrite and dense-dolomite nature of the Wichita forming the reservoir seal.The source for the oil, gas and helium accumulations are the sedimentary rocks of Pennsylvanian age in the Palo Duro and Anadarko Basins.
