Mt. Simon in northern Illinois is on the order of 0.1 m/year. Upward brine migration is <0.008 m/year on the regional scale, although brine
migration rate and volume is large. GCS-induced pressure buildup is less significant than pumping-induced
drawdown in northern Illinoisdrawdown in northern Illinois. If there is no significant salinity change in the worst pumping scenario in the 1980-
1990s, it is believed that GCS will not impact groundwater beyond that scenario.
5. Summary and Conclusions
An integrated model was developed to represent a hypothetical full-scale deployment scenario of carbon sequestration in the Illinois Basin
Simulated plume-scale behavior indicates favorable conditions for CO2 storage in Mt Simon: High-K and high-Φ Arkosic Unit provides Excellent CO Injectivity in lower Mt High-K and high-Φ Arkosic Unit provides Excellent CO2 Injectivity in lower Mt
Simon, Secondary seals Significantly Retards upward CO2 migration, Thick, extensive Mt Simon provides Large CO2 Storage Capacity, and Thick regional-scale Eau Claire seal ensures Long-Term CO2 Containment in the c eg o a sca e au C a e sea e su es o g e CO2 Co ta e t t e
storage formation.
Simulated basin-scale behavior indicates that High hydraulic diffusivity helps reduce pressure buildup in the core injection High hydraulic diffusivity helps reduce pressure buildup in the core injection
area, thus enhancing caprock geomechanical integrity, High regional caprock permeability allows for natural attenuation of pressure in
the storage formation, thus enhancing storage capacity of Mt Simon, Brine upward migration occurs in the core injection area, into a thick series of p g j
overlying saline aquifers and aquitards, at a maximum velocity of ~8 mm/year
5. Summary and Conclusions (Cont.)
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,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, Impact of GCS on shallow freshwater resources in northern Illinois may be less
than that ind ced b hea p mping from o erl ing fresh ater aq ifersthan that induced by heavy pumping from overlying freshwater aquifers.
Further research is needed to couple a regional groundwater flow d l ith th i t t d d l f i t l i tmodel with the integrated model for environmental impact
assessment
