| Abstract | A casting technique has been developed for making translucent replicas of the void space of natural rock Amnuation of light &n& through the cast combined with digital image analysis a pointwise definition of fracture apertures. The technique has been applied to a fracture specimen from Dixie Valley, Nevada, and the measured void space geometry has been used to develop theoretical predictions of two-~ phase relative permeability. A strong anisotropy in relative permeabilities has been found, which is caused by highly anisotropic spatial carrelations among fractrnt apertures. |
