Interaction of CO2 storage system materials with spCO2
Result description
Safety of any waste storage is based on safety functions of storage system components. CO2 storage multibarrier system comprises of injection borehole casing, cement, used for infill and plug and host rock. Their performance and behaviour in both short term and long term periods has to be studied in order to evaluate changes of the materials under CO2 and underground condition influence. The anthropogenic material changes are the most important parameters for injection borehole integrity and potential CO2 leakage. The presented results demonstrate interaction of materials that should fulfill safety function in the multibarrier CO2 storage system. Steel samples, cement and host rock samples were studied under long-term interaction with spCO2. Material and their property changes were then evaluated using XRD, TEM and BET measurements. Poster at Fourth EAGE CO2 Geological Storage Workshop.
