THE EFFECT OF VELOCITY ON PERMEABILITY BY GAS

Permeability is one the important parameters in petroleum industry. When the permeability is measured by liquid it is called absolute permeability. But when the permeability is measured by gas the permeability needs correction. There are four different regimes according to the Knudsen number In this paper the correction methods are discussed
