Evaluation of the Potential for Gas and CO2 Leakage Along Wellbores

Implementation of carbon dioxide (CO2) storage in geological media requires proper assessment of the risk of CO2 leakage from storage sites. Leakage pathways may exist through and along wellbores that penetrate or are near the storage site. One method of assessing the potential for CO2 leakage is by mining databases that usually reside with regulatory agencies.
