.... In addition, the diffusion of methane in the gas phase and gas-liquid relative permeability curves were evaluated to study the flow of the gas in the steam chamber. As observed in previous studies, we also found that the time of co-injection, the amount of NCG co-injected and the injection pressure...

... of SAGD, solvent co-injection with steam (called ES-SAGD) is also proposed. In both SAGD and ES-SAGD, the penetration of low viscosity gas phase into viscous bitumen induces fingering at the steam chamber edge, resulting in non-uniform steam chamber. In this study, for the first time, the phenomenon...
