Laboratory investigations of low and ultra-low permeable rocks of the Bazhenov Formation face serious problems, one of which is the determination of reservoir properties. Currently, there are several methods for measuring the permeability of rocks in range 10 −3 … 10 −9 mD. All of them include determination of permeability, both on plugs and crushed core. This work is concerned with comparison of results to determine the permeability of Bazhenov Formation rocks on plugs and crushed core. To determine the permeability on plugs, the steady state method, adapted for low and ultra-low permeable core samples, and the pulse decay method were used. The GRI method was used to study crushed samples. It is shown that, the proposed methods give a similar permeability values and can be used to determine permeability of Bazhenov Formation rocks.
