Abstract: An Example of a Carbonate Platform and Slope System and its Stratigraphically Equivalent Basinal Clastic System Springeran/Chesterian Relationships within the Anadarko Basin of Northwestern Oklahoma and the Texas Panhandle
An extensive regional study covering the Anadarko Basin of Oklahoma and Texas has been conducted which has included stratigraphic correlation with the generation of regional cross-sections, production allocation and reservoir characterization. While the entire stratigraphic section has been subjected to elements of this study, the Springer Group, Upper Mississippian and Lower Pennsylvanian, is the most demonstrative of a carbonate platform and slope system with its stratigraphically equivalent basinal clastic system.
Historically, the first carbonate encountered below the Morrow/Springer clastic section has been called the Chester Limestone by convention. Regional correlations in both Oklahoma and Texas from the deep Anadarko Basin, through the slope and onto the shelf, indicate that the Springer clastics of the deep basin are stratigraphically equivalent to Springer carbonate facies on the slope and shelf. As a result, Britt and Boatwright Carbonates have been identified which heretofore have generally been considered to be Chester. A highly conductive Boatwright Shale directly above the true Chester Limestone provides a very reliable regional marker at the base of the Springer Group over Oklahoma and Texas. Regional cross-sections showing trapping mechanisms, production maps delineating trends and lithofacies maps indicating depositional environments will be presented covering the Anadarko Basin and Shelf areas of both Oklahoma and Texas.
