Relative permeability and capillary pressure relations are assigned to each facies (Fig. 9).
As crevasse splays are often considered non-reservoir rock, only few measurements of their relative permeability and capillary pressure relations are available (e.g., Ramon and Cross 1997).
Finally, the resulting hydrodynamic pressure relations are combined with a fracture mechanics model to account for the change in the near-tip stress intensity.
It is therefore concluded that capturing wettability effects in capillary pressure relations is probably more important than trying to roll such effects into relative permeability functions.
The exploitation of entropy inequality resulted in temporally non-local generalized Darcy׳s laws for the liquid phases, near-equilibrium swelling and capillary pressure relations, generalized stress relations, near-equilibrium Gibbs free energy relation and the rate of evaporation relation.
Its weaknesses should be recognised, however, and constant pressure filtration tests, for example, which provide both sorptivity-, and equilibrium water content– pressure relations simply and accurately must ultimately be preferable.
