Effect of the Flow Rate on the Relative Permeability Curve in the CO2 and Brine System for CO2 Sequestration

The relative permeabilities of CO2 and brine are important parameters that account for two-phase flow behavior, saturation distribution, injectivity. CO2/brine permeability curves from the literature show low endpoint values high residual values. These most distinguishing aspects oil/water gas/oil. In this study, aspect is investigated experimentally by employing a wide range injection rates. As result, all measurements align with previous studies, having They have obvious relationships changes in rate increases, decreases, they converge to specific imply results displacement efficiency, but improvement efficiency decreases as increases. reasons identified concept viscous capillary forces, their significance into reservoir analyzed.
