Abstract: Wettability in CO 2 -brine-mineral/rock systems is an important parameter influencing CO 2 storage capacities and leakage risks in saline reservoirs. However, CO 2 tends to react with various minerals and rocks at subsurface conditions, thus causing temporal and spatial wettability changes. Although many relevant research works have been published during past years, a thorough overview of this area is still lacking. Therefore herein, reaction-induced wettability changes are reviewed, and the underlying mechanisms are discussed. Current research gaps are identified, future outlooks are suggested, and some conclusions are drawn. The fundamental understanding of reaction-induced mineral and rock wettability changes during CO 2 storage in saline reservoirs is analyzed and the guidance for long-term CO 2 containment security evaluations is provided.
