Abstract: Percolation theory was used to build relative permeability curves along the main axes of permeability tensor taking into account the hysteresis effect. Radius distribution measurements along the main axes of permeability tensor were taken for experimental reference. Such approach demonstrates the tensor nature of relative permeability. Accounting for the dependence of relative permeability on both displacement sequence and flow direction increases the accuracy of reservoir hydrodynamic models
