The carbon dioxide capture and storage (CCS) technology requires the evaluation of potential storage sites under the aspect of possible injection rates. The spreading of the CO2 displacement front depends on the flow through reservoir rocks and the displacement of pore fluids. As a measure for flow through a porous matrix, like different sandstones in saline aquifers, the permeability is commonly used. The gathered experimental data is analyzed by different equations and compared to pilot and commercial storage sites.
