Description
This powerpoint presentation begins by providing a brief overview of geologic carbon sequestration (GCS). Objectives were to: determine basin hydrogeology; have analogs for multiscale GCS processes; understand potential discharge/leakage pathways; and, know the scale of the problems. Topics covered include: site characterization; Illinois Basin hydrogeology; model development; and, simulation results. Conclusions indicate that an integrated model was developed to represent a hypothetical fullscaledeployment scenario of carbon sequestration in the IllinoisBasin, and simulated plume-scale behavior indicates favorable conditions forCO<sub>2</sub> storage in Mt Simon. Simulated basin-scale behavior indicates that: high hydraulic diffusivity helps reduce pressure buildup in the core injectionarea, thus enhancing caprock geomechanical integrity; high regional caprock permeability allows for natural attenuation of pressure inthe storage formation, thus enhancing storage capacity of Mt Simon; and, brine upward migration occurs in the core injection area, into a thick series ofoverlying saline aquifers and aquitards, at a maximum velocity of ~8 mm/year. The environmental impact on groundwater resources is presented. Includes tables, figures.
