Water saturation (S<sub>w</sub>) of a reservoir is a function of height above [[Free water level|free water]] (h) and pore type. S<sub>w</sub> interpretations should be made accounting for h, r<sub>35</sub>, and [[Connectivity and pore throat size|pore throat size distribution]] in the reservoir. The [[Calculating Sw from the Archie equation#What is the Archie equation?|Archie equation]] is the most widely used method of determining S<sub>w</sub>.
