Characterizing gas permeability and pore properties of Czech granitic rocks
Original language description
The main objective of this paper is to clarify the permeability of various Czech granitic rocks to describe the filtration properties and their changes due to hydrostatic pressure. In addition to permeability, rock properties that characterize the porous system (total porosity, water absorptive capacity and porosity determined by mercury porosimetry) were measured. Although the tested rock samples were intact, the permeability of granitic rocks can vary by more than four orders of magnitude depending on the sample location. The range of values varies from 10-16 to 10-20 m2 for a confining pressure of 5 MPa. The increase in hydrostatic pressure causes an additional noticeable decrease in the permeability.
