“…Additional deep saline formations that have been considered for GCS in the Illinois Basin include the Cambrian Potosi Dolomite and the Ordovician St. Peter Sandstone [36][37][38]. The Potosi Dolomite is a member of the Cambro-Ordovician Knox Supergroup and is known for vuggy and cavernous porosity [39].…”

“…While basin-scale SREs for the Potosi are not available, the SRE for the Knox Supergroup for the Illinois Basin ranges from 27.7 GtCO 2 to 239.7 GtCO 2 [34]. The St. Peter Sandstone ranges in thickness from 10 to 200 m, with the central and southern portions of the Illinois Basin meeting the criteria necessary for GCS [38,40,41]. The SRE for the St. Peter Sandstone in the Illinois Basin ranges from 579.9 MtCO 2 to 6.1 GtCO 2 [34].…”

Effects of Hydrogeological Heterogeneity on CO2 Migration and Mineral Trapping: 3D Reactive Transport Modeling of Geological CO2 Storage in the Mt. Simon Sandstone, Indiana, USA

We used three-dimensional (3D), high-resolution simulations facilitated by parallel computation to assess the effect of hydrogeological heterogeneity in the Mt. Simon Sandstone on CO2 plume evolution and storage and geochemical reactions in a portion of the Illinois Basin, Indiana. Two scenarios were selected to investigate the effects of the hydrogeological heterogeneity in 3D reactive transport simulations: a heterogeneous case with variable porosity and permeability, and a homogenous case with constant porosity and permeability. The initial pressure, temperature, and mineralogical distributions are consistently applied in both the heterogeneous case and the homogeneous case. Results indicate that including hydrogeological heterogeneity in 3D reservoir simulations for geological CO2 storage significantly impacts modeling results for plume migration patterns, CO2-water-mineral interaction, reservoir quality, and CO2 plume containment. In particular, results indicate that (1) the CO2 plume reached the top of the Mt. Simon Sandstone in the homogeneous case, but was restrained to the lower third of the formation when hydrogeologic heterogeneity was considered; (2) the dominant trapping mechanism in the heterogeneous case was mineral trapping (43%), while it was solubility trapping (47%) in the homogeneous case (at 10,000 years); (3) incorporating reservoir heterogeneity in the model leads to a higher likelihood of long-term containment.
