The network model is used to show that wetting phase relative permeability of porous media is only slightly influenced by the fraction of that phase trapped in dead-end pores. On the other hand, the trapping of nonwetting phase in dead-end pores is a major influence on the shape of the nonwetting phase relative permeability curve. Laboratory experiments on porous media are suggested to test these network model predictions.
