Capillarity is the power of pressure between the two types of fluid immissicible. Based on capillarity power will be able to determine the level of the fluid content wettability of rock.

Wettability is the ability of fluid to wetting the rocks, that the value is represented by contact angel (θ). The cut off limit wettability is θ = 90°. If θ<60°, then the rock are water wet, and if θ>120° the rock has oil/gas wet. Intermediate wet has gotten if the θ around 90° (between 60° and 120°).
