From: Assessing the potential of solubility trapping in unconfined aquifers for subsurface carbon storage
Left plot: Comparison of CO2 concentration profiles at the well versus depth after 100 years of injection for systems having kv/kh ratios of 1:10, 1:1 and 2:1. The water to CO2 injection mass ratio is 22:1 for the kv/kh ratio of 1:10, and 25:1 for the kv/kh ratio of 1:1 (reference system), and kv/kh = 2:1 as indicated in the plots.Center and right plots: 2D cross-sections for the CO2 mass fraction and gas saturation, which is the mass fraction of exsolved CO2 in the pore fluids, for the three modelled systems after 50 and 100 years of carbonated water injection.
