Capillary Pressure

Capillary Pressure Contours

• BVW: empirical expression of
• pore throat distribution
• capillary pressure
• hydrocarbon column
• Plot Sw vs. phi on Pickett crossplot at constant Cp (height above FWL)
• Convergence of Cp contours at higher pressures where BVW changes only gradually
• Assume similar pore type for connected points
