Carbon storage is considered to be a necessary technology in bridging the transition to a low carbon energy mix. Environmental risks related to the geological storage of CO2 such as well leakage, fault reactivation, seismicity and caprock failure, need to be minimized. In this work, we developed a probabilistic model to assess the risk of cement sheath failure and the associated well leakage. The approach integrates a finite element model for well integrity analysis with a probabilistic model based on Bayesian Belief Networks (BBN).
