− | 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 pore throat size distribution in the reservoir. The Archie equation is the most widely used method of determining S<sub>w</sub>. | + | Water saturation (S<sub>w</sub>) of a reservoir is a function of height above [[Free water level|free water]] (h) and pore type.
