N2 - An integrated model was developed to represent a hypothetical fullscale deployment scenario of carbon sequestration in the Illinois Basin &bull Simulated plume-scale behavior indicates favorable conditions for CO 2 storage in Mt Simon: &bull High-K and high- Arkosic Unit provides Excellent CO2 Injectivity in lower Mt Simon, Alternating layering Significantly Retards upward CO2 migration, &bull Thick, extensive Mt Simon provides Large CO2 Storage Capacity, and &bull Thick regional-scale Eau Claire seal ensures Long-Term CO 2 Containment in the storage formation. Simulated basin-scale behavior indicates that &bull High hydraulic diffusivity helps reduce pressure buildup in the core injection area, thus enhancing caprock geomechanical integrity, &bull High regional caprock permeability allows for natural attenuation of pressure in the storage formation, thus enhancing storage capacity of Mt Simon, &bull Brine upward migration occurs in the core injection area, into a thick series of overlying saline aquifers and aquitards, at a maximum velocity of 8 mm/year &bull Environmental Impact on Groundwater Resources Environmental concerns of brine migration into the updip Mt Simon in northern Illinois and southern Wisconsin may not be an issue, Moderate pressure buildup is obtained in northern Illinois, where upward brine migration might be a concern, if local seal imperfections exists, &bull Impact of GCS on shallow freshwater resources in northern Illinois may be less than that induced by heavy pumping from overlying freshwater aquifers. Further research is needed to couple a regional groundwater flow model with the integrated model for environmental impact assessment. 2009 American Water Works Association.
