Abstract

We present and discuss the results of a comparative study of two laboratory procedures for the determination of the capillary gas breakthrough pressures of low-permeable lithotypes with intrinsic permeability coefficients below 10-20 m2. Well-characterized and mineralogical homogeneous core section of the Opalinus Clay (Mont Terri) were used in this study. The experimental conditions corresponded to a depth of approximately 1500 m depth, representative of a typical CO2 storage scenario (30 MPa confining pressure, 45°C).
