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
