Dynamic effect in capillary pressure-saturation relationship for CO2-H2O-sand system: application to CO2 sequestration

The non-uniqueness in capillary pressure (Pc) and saturation (S) relationship is of concerns to researchers of two-phase systems in porous media. This is because of its effect on the effective monitoring and control of the two-phase flow in porous media, especially the case of CO2-brine system encountered in geological carbon sequestration. This work aims to investigate the dynamic effects in Pc-S relationship for CO2-water system and quantify it by the parameter known as the dynamic coefficient.
