This report assesses the carbon dioxide (CO2) storage capacity for the Knox Group and the Stones River Group in the Mississippi Black Warrior Basin. The results of this evaluation are complimentary to the Geologic Survey of Alabama (GSA) evaluation of potential CO2 storage reservoirs in the Alabama Black Warrior Basin. The Stones River Group directly overlies the Knox Group and it contains documented porous zones that may be promising for CO2 sequestration. The Cambrian-Ordovician interval is a thick sequence of carbonates that occurs in multiple geologic settings in the Southeast Regional Carbon Sequestration Partnership (SECARB). The Knox and Stones River Groups could likely only serve as a CO2 storage reservoir in the southern region of its occurrence, within the Black Warrior Basin. Recorded high porosity zones in the Stones River Group, are likely discontinuous and inconsistent horizons; making it difficult to determine the potential CO2 storage capacity. Increased data coverage of the Knox and Stones River Groups and a detailed study on injectable zones in these formations would provide a clearer picture on their potential for CO2 storage.
