A New Model For Calculate Capillary Pressure And Relative Permeability In Reservoir Rocks Based On Pore Network Modeling

Summary To gain insight in relationships among data like capillary pressure and relative permeability in reservoir rock, we have developed a model for petroleum reservoir rocks. In petroleum engineering we are limited in capillary pressure and relative permeability data. We need capillary pressure and relative permeability data in multiphase reservoirs to have better recognition about phase behavior in reservoir rock and that’s very important in reservoirs simulation. We have shown that our model produce distinctly different curves for capillary pressure and relative permeability. We have investigated some basic issues such as effect of network size, network dimension, and different trapping assumptions in the two networks. We have generated pore network of reservoir according cubic pore network model. After that we have studied fluid behavior in our network and also we have applied transport phenomena equations in fluids that are present in our network as a reservoir rock
