gas permeability has been measured on a suite of cores from the spirit river tight gas sand of western alberta and on two samples from the cotton valley formation of east texas. using nitrogen as the mobile fluid, the author has measured permeability as a function of partial water saturation at pressure and confining pressure samples from both locations show strong dependence of permeability (k) on effective pressure and degree of water or brine saturation the validity of darcy's law in the microdarcy range has been verified in a dry spirit river sample. 7 refs
