..., that when the water saturation gets to be around Sw i , and oil saturation decreases down to around 20%, the oil relative permeability falls down to zero. Realizing that Stone-II is based on statistical proncipals rather than physics of fluid-flow alone, this vanishing of Kr o is clearly a mathematical...
