Predicting effects of wettability variations on displacement behavior and their incorporation into inflow performance

Wettability plays a crucial role in reservoir fluid dynamics. Wettability controls the initial fluid distribution, fluid movement, further displacement of one fluid by another and hence effecting recovery from a reservoir. Wettability also has strong influence on capillary pressure and relative perm...

Wettability controls the initial fluid distribution, fluid movement, further displacement of one fluid by another and hence effecting recovery from a reservoir.
