N2 - One of the most interesting enhanced oil recovery methods is carbonated water. This subject has been noticed especially during recent years for addressing out its effective mechanisms. When smart brine is used for carbonated water injection, there is a competency between ions and carbon dioxide to be dissolved in water. Therefore, the produced carbonated water results in higher recovery factor due to the activation of coupled mechanisms. Whenever smart carbonated water is injected, an acidic media is provided which results in mineral dissolution and transfer from the porous media to the fluid. In this paper, it is intended to investigate how do carbonate and sandstone cores are affected when smart carbonated water is injected by using core flooding tests and mineral analysis. It is found that rock dissolution depends on brine concentration and rock minerals. The highest rock dissolution was detected in carbonate and to less extent in sandstone cores.
