Abstract: Determining the characteristics of the dynamic behavior of carbon dioxide in a rock mass is a stage in the process of assessing a potential CO 2 storage reservoir. The aim of this study was to analyze the process of CO 2 storage in saline aquifers of the selected regions of the Upper Silesian Coal Basin in Poland. The construction of dynamic simulation models was based on static models of real deposit structures developed on a regional scale. Different simulation variants of the CO 2 storage process were adopted, varying in terms of injection efficiency and duration of individual simulation phases. The analysis examined the influence of the degree of hydrodynamic openness of the structure on the CO 2 storage process, in each of the variants. The results of numerical simulations showed that among the three analyzed geological formations, the D?bowiec formation is the most prospective for potential CO 2 storage and is characterized by the most favorable geological and hydrogeological parameters. In the best variant of the simulation, in which the safety of CO 2 storage in the rock mass was taken into account, the total amount of CO 2 injected in a single directional well was approximately 8.54 million Mg of CO 2 during 25 years of injection.
