Coroiate or irreducible water saturation (Swi) Irreducible or connate water saturation (Swi) and residual oil saturation (Sor) both can vary and residual oil saturation (Sor) are critical widely from less than 10% to more than 60%. end points at which there is negligible relative Experiments in physical models and reservoir rocks permeability to water and to oil respectively.
