Abstract (Summary)

Production from the lower Mississippi Lime sediments is spotty throughout northern Oklahoma. Evaluating the stratigraphy and various properties of the St. Joe Group (Pierson Limestone, Pierson A, Pierson B, Northview Shale, and Compton Limestone) is necessary to better understand proper well location for the most successful and cost-effective production possible. This study focuses on an area that covers the shelf edge of the Anadarko Basin. Formation tops are picked and maps are created using multiple programs within Geographix to cover Grant, Garfield, and Alfalfa counties in northern Oklahoma. Available core data from one well is used in studying the porosity, permeability, and mineralogy of each formation. Results from subsurface mapping and core data examination show that of the formations of interest, the most ideal for production is the Pierson B, a sandy formation with the most optimal porosity and permeability. The majority of the study area is water-wet, but where production is possible fracturing may be necessary to produce economically. The thickness of the Waulsortian-type Compton Limestone appears to have some control over the water saturation of the shallower, Pierson B. Where the Pierson B is most water-wet is where the Compton Limestone is thickest, and where the Pierson B is least water-wet is along the flanks of these limestone mounds.
