CO2 WAG Performance Sensitivity to Relative Permeability and Wettability Assumptions in Compositional Simulation
Water alternating gas (WAG) injection is widely applied in CO2 EOR to improve sweep efficiency and mobility control, yet forecasted WAG performance is often dominated by uncertainty in relative permeability, three-phase behavior, and cycle hysteresis. This study isolates the impact of relative permeability and wettab...
