摘要

•Capillary pressure becomes significant when pore sizes in a porous medium are in nanometer scale.•Capillary pressure in nanoscale influences the phase-behavior because (Pc=PL−PV).•Peng-Robinson equation of state is modified.•Consideration of pore size and radius distribution.•The effect on bubble point of Bakken oil fluid is investigated.
