Witryna17 paź 2024 · Abstract. Wettability is defined as the preference of one fluid to spread or adhere to a solid surface in the existence of other immiscible fluids. In two phase system, the phase which tends to adhere to the rock (solid) surface is known as the wetting phase. The other phase is the non-wetting phase. The wetting phase tends to occupy … Witryna1 dzień temu · Abstract. The wettability of reservoir rocks saturated with oil and water is one of the most important factors influencing petrophysics and oil recovery.
