CO2 sequestration in subsurface geological formations: A review of trapping mechanisms and monitoring techniques

Carbon capture and storage (CCS) in subsurface formations has emerged as a promising strategy to address global warming. In light of this, this review aims to provide a comprehensive understanding of the mechanisms involved in the geological trapping of CO2. Additionally, it aims to identify the techniques used to evaluate the potential for CO2 sequestration before injecting CO2 into subsurface formations and the methods used to monitor the progress of CO2 sequestration after injection. The review also presents future research directions based on current research trends in the field. Four principal trapping mechanisms were identified: structural, capillary (residual), solubility, and mineral trapping. These…
