Measured and calculated conductivities as a function of confining pressure. Conductivities are normalized by the fluid conductivity. The percolation model (Johnson and Manning 1986) was employed for the calculation of conductivity. The crack occupancy fraction is assumed to be proportional to crack porosity. The crack porosity was obtained from the volumetric strain measurement of dry rock sample AJG07
