... the caprock. During a batch-wise injection of CO 2 , the wellbore is submitted to thermal loading cycles. After injection, the near-well materials, including cement sheath, are exposed to a CO 2 -rich environment, especially in the vicinity of the reservoir. These thermal cycles (TC) and exposure environment...
