Modeling of the CO2 long-term periodic injection experiment (CO2LPIE) into stratified hard clay rock at Mont Terri

CO2 Long-term Periodic Injection Experiment (CO2LPIE) aims at investigating the caprock sealing capacity in geologic carbon storage in a highly monitored environment at the field scale. The experiment is carried out in the sandy facies of Opalinus Clay at the Mont Terri rock laboratory, Switzerland, to gain knowledge on the changes in the geomechanical properties induced by the geochemical reactions resulting from CO2 injection (Rebscher et al., 2019; 2020). The presence of bedding planes in Opalinus Clay is responsible for its anisotropic hydrogeological and geomechanical behavior.D.S., V.V. and I.R.K. acknowledge funding from the European Research Council (ERC) under the European Union’s Horizon 2020 Research and Innovation Program through the Starting Grant GEoREST (www.georest.eu) (Grant agreement No. 801809).
