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) [...]

What Pressure of Gas to Use for Measuring Permeability & Why Does Saturation Not Match Fluid and Gas in Pores? | Ask PERM

Julie Asks PERM: I have two main questions if you could help me: -How to choose the pressure of gas if we want to measure the permeability of a reservoir rock?  -When doing the saturation, is it possible that the pore volume is much higher than the fluid volume, if yes, what could be in the [...]
