The Phase II project involved a significant refinement and increased understanding of the region’s geologic storage potential through the collective efforts of the team of geologic experts from each of the region’s nine states. The regional mapping and delineation of geologic sequestration potential was led by Ohio Division Geological Survey, as well as Kentucky Geological Survey - University of Kentucky, Indiana Geological Survey, Maryland Geological Survey, New Jersey Geological Survey, New York State Museum Institute, Pennsylvania Geological Survey, Rutgers University, West Virginia Geological Survey, and Western Michigan University.
The MRCSP geology team conducted regional characterization of the following geologic formations: Upper Cambrian/Mount Simon Sandstone; Middle Silurian-Middle Devonian (MSDS) units; oil and gas/enhanced oil recovery fields; Middle and Upper Devonian shales; and unmineable coal beds/enhanced coalbed methane recovery. Refinement of earlier Phase I estimates of regional storage capacity in the MRCSP’s deep geologic formations further confirmed the potential for storing at least a century’s worth of carbon dioxide emissions from all the region’s major sources of carbon dioxide. While saline formations have the greatest sequestration capacity, the geologic characterization work also underscored opportunities for enhanced oil recovery and storage in the region. Further study would provide a greater understanding of how to optimize production and storage operations, as well as staging of carbon dioxide sources. A summary report and five topical reports documenting the results of these efforts are now available for viewing here:
