International audience Saline aquifers are choice targets for geological storage of CO2because of their storage potential andbecause these formations are not suitable for other uses. Geochemical modeling is an interesting tool toassess the geochemical behavior of CO2in the saline aquifer, including its dissolution in the brine andits interactions with minerals. Two key parameters which determine the confidence one can have in theresults of geochemical modeling are tested in this paper: (i) the establishment of the conceptual model,including the selection of the primary and secondary minerals expected to react; and (ii) the activitymodel and the associated thermodynamic databases to calculate the interaction energies within thesaline solution. In this study, we performed an analysis of a large set of CO2storage natural analogs, whichmakes it possible to identify the minerals that are likely to precipitate and dissolve during CO2-brine-rockinteractions.
