Abstract

Wettability and contact angle of fluids affect the process of CO2 injection in aquifers. However, previous studies have been limited to simpler equations of state and focusing on fluid properties without enough emphasis on fluid-surface adhesive interaction. Thus, this paper addresses that gap by studying the effect of the wettability in the effective CO2 injection using the Peng-Robinson EoS. For that purpose, the interaction parameter of the pseudopotential wetting force is adjusted to modify the contact angles to compare the penetration of CO2 in the porous medium saturated with water. The model is validated using the suspended droplet stability and the sessile droplet contact angle test. The study found that a smaller contact angle and therefore decreased wettability of the porous surfaces is overall beneficial to CO2 injection.
