Figure 5.12: Relative permeability curves for (a) pore network R 1 and (b) pore
network R 3 (pore network R 2 showed similar results and is not shown here). The
plots with g ∗ = 1.3E − 3 show the case of cubic pore bodies (45dge angles). The
solid lines (without markers) show the relative permeability when the resistance
to the flow within pore bodies is neglected.
From Figure (5.12), it is clear that including the resistance to the flow within
the pore bodies results in considerably smaller values for k r . That is, neglecting
the resistance to the flow within pore bodies will cause overestimation of the
relative permeability. Clearly, this overestimation is less when pore bodies have
high values of conductances.
