(a) Capillary pressure () and (b) CO₂ saturation () with respect to pore volume for 0^o cored Berea sandstone injected with scCO₂ for 25 ml/min. (c) Residual capillary pressure () and (d) the residual CO₂ saturation () for directionally cored specimens with increasing flow rate when injected with scCO₂.
