How to Calculate Water Saturation After Trimming a Plug? | Ask PERM

Julie Asks PERM: After re-trimming, is the water saturation just obtained by the subtraction of the volume of the initial plug to the re-trimmed plug? What I mean is,  As, Sw=Vw/Vpore Sw: water saturation Vw: volume of water collected Vpore: pore volume Can we use this formula after retrimming: Sw = (Vw * Vpa) / (Vp*Vpore) [...]
