Sensitivities (red) and induced errors (green) of uncertain parameters on the mass of injectable CO₂. (1) Maximum overpressure at injection point (uncertainty of 1% of the initial pressure), (2) porosity (uncertainty of 50% of the initial values, (3) horizontal permeability (uncertainty of 80% of the initial values), (4) rock compressibility (uncertainty of 50% of the initial value), (5) faults sealing (multiplying transversal transmissibility factor equal to zero or 1), (6) CO₂ dissolution (modeled or not), (7) irreducible water saturation (uncertainty of 50% of the initial value) with dissolution modeling, (8) vertical permeability anisotropy ratio (0.1 or 0.0001), (9) irreducible water saturation (uncertainty of 50% of the initial value) with no dissolution modeling.
