CHARACTERIZATION OF OSAGEAN AND KINDERHOOKIAN STRATA OF NE OKLAHOMA

Mississippian strata of the midcontinent are prolific hydrocarbon reservoirs but also prove very challenging to geologists working the play. In this work, it is proposed to construct the stratigraphic framework of the Mississippian section of northeast Oklahoma, while also determining their spatial distribution in the subsurface. In order to accomplish this, the stratigraphic position of these rocks in the subsurface must be determined. A broad description of lithology is intended for the study area, while also determining the distribution and depositional direction of prograding wedges within the Mississippian section. The study area is located in northeastern Oklahoma on the Cherokee Platform and is situated on the southwest flank of the Ozark dome. This area was located between 10-15 degrees south of the equator, on a shallow water carbonate platform known as the Burlington Shelf during early Mississippian time. This study will encompass 274 townships from T29N to T17N and R1E to outcroppings of Mississippian strata to the east. Thorough investigation will be carried out through methods such as subsurface geologic mapping, well log correlation, Formation Micro-Imager (FMI) log interpretation, core descriptions, outcrop studies, and geospatial analysis. The results of this work will better provide an insight to the depositional environment, spatial distribution, stratigraphic position, and origin of Mississippian strata in the subsurface of northeast Oklahoma. The product of this work will further the understanding of Mississippian strata in the subsurface of the midcontinent and help constrain the deposition of the Mississippian section.
