VPPS Byte 2: Critical Water Saturation, What is it and how it impacts NMR and Capillary Pressure mobile water

Critical Water Saturation One key petrophysical property that has been overlooked when interpreting whether mobile water is present in a reservoir is the critical water saturation (Swcr).  This saturation is an estimate of the minimum connate water saturation  (Sw) above which the relative permeability to water (Krw) allows water to flow in the reservoir. This […]
