Regional Sequence Stratigraphy and Reservoir Geology of the Granite Wash, Anadarko Basin, Texas and Oklahoma
Geology/Petroleum Geology, University of Oklahoma, Norman, OK, USA
The Pennsylvanian aged strata within the Anadarko Basin of the eastern Texas panhandle and Oklahoma have been actively produced since the 1920s. Despite the long production history within the basin very little work has been done to enhance our understanding from a sequence stratigraphy perspective; which has led to a general trend of potentially under characterized reservoirs. Establishing a regional sequence stratigraphic framework will allow for a more complete understanding of currently producing fields in addition to aiding future exploration within the basin. Reevaluation of productive fields based on the broader stratigraphic framework can aid in the understanding of where to expect reservoir compartmentalization and potential future opportunities. This will also allow provide a guideline that can assist in the prediction of sedimentary deposits to narrow down and target the areas presenting the greatest potential.
Previously published work on the sequence stratigraphy of the Anadarko Basin has focused solely on the productive Cleveland and Marmaton formations within a small portion with the basin (T.F. Hentz and W.A. Ambrose). The Granite Wash also consist of productive groups above and below the Cleveland and Marmaton formations that have yet to be characterized in this type of study.
The focus of this work will be to establish a basin scale sequence stratigraphic framework for the Granite Wash intervals derived from well data located within the Oklahoma portion of the Anadarko Basin. As a result, regional maps of the basin will be generated showing Granite Wash groups within their respective depositional systems tracts.
