Abstract
Carbon Capture and Storage (CCS) is crucial for mitigating carbon dioxide (CO2) emissions from industrial activities. The Paleozoic sedimentary basins in Texas are significant reservoirs for hydrocarbon production and have shown potential for CCS. However, thorough site screening, ranking, and characterization are necessary to identify the most favorable geologic units within each basin for the secure and long-term storage of CO2. This project determines the CCS potential of the Fort Worth Basin in North Central Texas through a modified method of basin screening, and examines and determines the most promising geologic intervals within a highly suitable area of the basin. The screening and ranking method then ranks various geologic units across five areas of the Fort Worth Basin, taking into account regional and local geologic and economic factors as well as industrial activities and their impact on sedimentary strata for CO2 storage. The geologic units include the Cambrian and Ordovician dominated by limestone, Mississippian dominated by shale, and Pennsylvanian and lowermost Permian characterized by interbedded shale, sandstone, and limestone. These five areas, including the northeastern, eastern, southern, western and Bend Arch regions, are divided based on Paleozoic tectonic and subsidence history. Our results show that the Pennsylvanian and lowermost Permian units in the eastern, Bend Arch and northeastern areas have the highest suitability, and the Mississippian units throughout the basin have the lowest average suitability. The CCS potential of the Pennsylvanian and lowermost Permian in the northeastern basin and other surrounding areas, including Tarrant, Parker, Jack, Wise, and Denton counties, are further investigated through well log correlations, reservoir characterization, and CO2 migration modeling.
