The behavior of oil well cement at downhole CO2 storage conditions: Static and dynamic laboratory experiments
One of the major technological issues for CO 2 injection is the long-term behavior of the cement-based materials used to ensure the overall sealing performance of the storage wells. When water is present, the CO 2 injected can react chemically with the cement (i.e. carbonation). The objectives of our experimental program are to assess the kinetics and phenomenology of the changes that occur in class-G Portland cements exposed to CO 2 -enriched aqueous fluids at 8 MPa and two differentdoi:10.1016/j.egypro.2011.02.504 fatcat:3n7dbd7ofjbzfjuqtuky7btjuy
