In geological sequestration, CO2 is injected in liquid form, but it transforms into a supercritical fluid (scCO2). Having density lower than the aqueous brine, initially saturating the reservoir rock, scCO2 tends to buoy through it, in continuous contact with the brine, and therefore to accumulate below the caprock.
Significant contributions in the literature have been focused on the study of the response of the reservoir rock to CO2 injection, however less results are available concerning the direct interaction between the acidified solution stored in the aquifer and the caprock.
The objectives of the research activity will be to reproduce at the laboratory scale scenarios representative of the interactions between the acidic solution stored in the reservoir rock and the sealing caprock.
