Numerical simulations of supercritical injection of CO2 in Dunajovice Sandstone

Popis výsledku v původním jazyce

CO2 storage is a promising technology to enable further use of coal resources without CO2 emissions damaging climate. In the Czech Republic, The Dunajovice Sandstone reservoir has been identified as an ex-ample of a typical structure suitable for potential geological storage of CO2 in the Carpathian Foredeep ar-ea, and served as a pattern for modelling and simulation purposes in this project. Once injected, CO2 propa-gates in its supercritical form and partially dissolves into groundwater. This processacidifies brine and trig-gers geochemical reactions with the injection wellbore cement, the host rock, as well as the cap rock. These reactions must be quantified and assessed to ensure the security and sustainability of the storage. Here we use the geochemical codes TOUGH2 and TOUGHREACT to estimate the plume propagation as well as the geochemical effects of CO2 underground injection. Results show a good compatibility of hydrogeological pa-rameters with a 30 years high-rate CO2 injectio
