Abstract:
High resolution imaging of the microstructure of
Fontainebleau sandstone allows a direct comparison
between theoretical calculations and laboratory
measurements. While porosity, pore-volume-to-surface
ratio, permeability, and end point relative permeability
are well predicted by our calculations, we find that
electrical resistivity and wetting phase residual
saturation are both overestimated.
