Predictive modeling of CO 2 storage sites requires a detailed understanding of physico-chemical processes and scale-up challenges. Dramatic injectivity decline may occur due to salt precipitation pore clogging in high-salinity aquifers during subsurface CO 2 injection. This study aims to elucidate the impact of CO 2 -induced salt crystallization in the porous medium on the geomechanical properties of reservoir sandstones. As t...
