Pore-Scale Characterization and PNM Simulations of Multiphase Flow in Carbonate Rocks
Energies, 2021 This paper deals with pore-scale two-phase flow simulations in carbonate rock using the pore network method (PNM). This method was used to determine the rock and flow properties of three different rock samples, such as porosity, capillary pressure ...
