Chapter 7 provides some preliminary results on two phase flows in fractured porous media. The classical equations on the Darcy scale are presented as well as the van Genuchten constitutive relations for the relative permeabilities and the capillary pressure. Some numerical details are given, but basically the same finite volume technique is used. The two classical examples of parallel fractures and sugar box reservoirs are briefly illustrated and discussed. Then, the general situation of two phase flow in random networks is addressed; first, transients in a three dimensional fractured porous medium are presented; second, some examples of upscaled relative permeabilities are given and discussed; systematic calculations made in the capillary dominated regime for two media with different fracture densities are well approximated by a simple model.
