Simulation of the absolute permeability based on the capillary pressure curves using the dumbbell model

The paper deals with simulation of absolute permeability of granular collectors based on the capillary pressure curves using the dumbbell model. It has been established that for assessing permeability based on the capillary data, effective porosity should be used, since residual water does not participate in the displacement of fluid from the rock sample. It was proved that when using the dumbbell model instead of a simple capillary model, accuracy of absolute permeability prediction based on the capillary pressure curves increases significantly.
