This paper presents preliminary estimations of CO₂ overpressure into the reservoir and CO₂ leakage through the caprock and the overburden. A simple, two-phase flow model in porous media based on Darcy’s law was used, in order to explore easily long time periods. The models produced by COMSOL Multiphysics allow sensitivity studies and preliminary evaluations of the relations between CO₂ leakage (time needed for the CO₂ to reach the surface; value of the CO₂ flowrate at the steady state), the caprock characteristics (thickness and permeability) and CO₂ overpressure.
