Abstract

Gas slip phenomena in low-permeability media are typically accounted for by means of the conventional Klinkenberg correction. This correction is derived from gas permeability tests conducted under different pore pressures. An alternative method for obtaining the Klinkenberg correction is given which uses the results from gas permeability tests conducted with different gases under the same pore pressure. Both methods have been applied to a series of gas permeability measurements on rock salt. Changes in the pore structure during permeability testing precludes use of the conventional Klinkenberg method. The alternative method is successful when permeabilities are measured with steady-state techniques.
