Abstract

It is essential to understand the relative permeability of CO2 and brine when characterizing the flow of CO2 as it is injected into an aquifer. The relative permeability of CO2 and brine has a significant impact on CO2 migration and saturation distribution. This paper presents the results of experimental investigations into the effects of the viscosity ratio and interfacial tension (IFT) on steady-state relative permeability. A series of unsteady-state experiments were conducted with a wide range of flow rates. These enabled us to determine the low end-points of the relative permeability and high residual brine saturation of the two-phase CO2/brine system.
