WebApr 26, 2024 · Imbibition is often analogous to the waterflooding process. The primary drainage and imbibition relationships generally differ significantly, as shown in Fig. 15.4 for a gas/water system. This difference is called capillary pressure hysteresis—the magnitude of capillary pressure depends on the saturation and the direction of saturation change. WebThen, imbibition experiments were simulated by decreasing the nonwetting phase pressure in small steps. Imbibition always started from the smallest pores with the highest entry capillary pressure. At each imbibition step, the forced displacement rule was imposed. At the end of imbibition, the drainage simulation was repeated.
