CO2 capture and storage constitutes a promising solution to control and reduce these emissions. Wellbore integrity is a key challenge to ensure long term safety and for public acceptance. For this objective, a two-phase flow model in porous media based on Darcy’s law has been proposed to simulate the CO2 leakage within the well at a rat hole area.

The numerical simulations have highlighted competition between the effects of gas and liquid flow in this specific area. COMSOL Multiphysics was able to demonstrate the effect of the water flow on the CO2 leakage.
