Problem 9 – Simulation of Supercritical CO₂ into a Deep Saline Aquifer (CO₂ Sequestration)

Abstract: One viable scenario for geologic sequestration of anthropologic CO₂ is its injection into deep saline aquifers. To evaluate the potential for a field application of this scenario, numerical simulations of the CO₂ injection process will be necessary. In the absence of long-term field experiments, which will be cost and time prohibitive for most applications, numerical simulation is the most comprehensive means for predicting the complex behavior of multiple fluids under complex hydrogeologic conditions and evaluating the feasibility for geologic sequestration of CO₂. Numerical simulations will additionally provide critical information required to obtain regulatory permits and satisfy stakeholder concerns prior to injecting CO₂, including reservoir pressure, CO₂ migration and dissolution behavior, and the potential for leakage to the ground surface.
