Hydraulic barrier design and applicability for managing the risk of CO2 leakage from deep saline aquifers

A proper risk management scheme for CO2 storage should include an adequate monitoring plan completed with a site-specific intervention plan in order to demonstrate that any undesired consequence can be prevented, if not corrected. In the case of CO2 escape from the storage reservoir to an overlying aquifer through a vertical conduit (representing the degraded cement of a well or a permeable fault), directly modifying the leak hydraulic...
