Summary:The permeability tests, using a transient pulse method, were carried on KIMACHI sandstone under various confining and pore pressures. From the experimental data, it is recognized that permeability is underestimated when it is assumed that there is no storage in the rock specimen. Also, permeability increases as the pressure difference between both end pore pressure of the rock specimen increase. Under constant pore pressure, permeability decreases gradually as confining pressure becomes higher. But, it is found that permeability is remarkably affected by pore pressure rather than by confining pressure. Under constant confining pressure, permeability decreases as differential stress increses. With further increase in differential stress, permeability increases.
