Here we report on the framework of geological site exploration, which encompassed investigations at different scales prior to and after the drilling of the three CO₂SINK boreholes. Past and new exploration data are integrated to delineate at regional scale (1) the geological structure of CO₂ storage formation and its overburden, including fault systems as potential fluid pathways and (2) the shallow hydrogeology and the groundwater flow directions for an assessment of effects in case of CO₂ leakage and migration. The poro-perm facies and mineralogical composition of the CO₂ reservoir rock and the top seal formation were studied by routine and special core analyses, including the measurement of porosity, gas and brine permeability, and by XRD analysis.
