Abstract

This thesis reports on experimental work conducted to measure porous media properties relevant to Enhanced Gas Recovery (EGR), particularly as they pertain to more realistic partially (water) saturated rocks, and a preliminary study on C02 foam stability for EGR applications. EGR involves C02 injection into natural gas reservoirs to both increase gas recovery and trap C02. In the work presented here dispersivity (a) and tortuosity (-r) are quantified in sandstone rock plugs as a function of residual water fraction. A study of C02 foam stability is also presented, particularly as a function of various liquid and gas compositional factors.
