The CO2-Vadose project: Experimental study and modelling of CO2 induced leakage and tracers associated in the carbonate vadose zone

► Establishment of an experimental monitoring strategy of gas phases during a leakage. ► Comparison between an experimental leakage in the vadose zone and a model (COORES). ► Utilisation of noble gases (He and Kr) as precursors to monitor CO2 leakage. ► Experimental simulation of a leakage of CO2 in the carbonate vadose zone. ► Nature of the parameters involved in the diffusion of CO2 in carbonate vadose zone.
