Water saturation distribution in a reservoir (view source)

The distribution of water saturation values within a reservoir depends on the height above free water, hydrocarbon type, pore throat-size distribution, and pore geometry. Mapping S<sub>w</sub> distribution in a reservoir helps us predict trap boundaries.

Bulk volume water (BVW) equals Φ × S<sub>w</sub>. In zones with the same pore type and geometry, BVW is a function of the height above the [[free water level]]. Above the transition zone, BVW is fairly constant. Below the transition zone, BVW is variable.
