In this paper the results of finite element method nitrogen flow simulations are presented. Finite element mesh wascreated on the basis of carbonate rock X-ray computed microtomography images. Nitrogen flow was simulated in COMSOL Multiphysics 3.5. Calculated permeability was consistent with the permeability measured with the use of gas permeability test. The results have shown that combined X-ray...
The study presents data of laboratory examinations carried out on drill cores originating from various facies of Upper Rotliegend formations within Foresudetian Monocline, aimed at evaluation of their pore space structure. The results were obtained from X-ray computed microtomography (micro-CT) data. It has been found that rock samples representing Aeolian dune sandstones of A2 facies featured the...
