Experimental study of the effect of variation in in-situ stress on capillary residual trapping during CO2 geo-sequestration in sandstone reservoirs
During a geo-sequestration process, CO2 injection causes an increase in reservoir pore pressure, which in turn decreases the reservoir net effective stress. Changes in effective stress can change all the reservoir and cap-rock properties including residual saturations. This article presents the resu...
