Abstract

CO2 sequestration in saline aquifers has been of interest as an option to reduce concentration of CO2 in the atmosphere. Of all the mechanisms of sequestration, mineral sequestration is proved to be the most secure one. In this study, formation of carbonates is investigated through monitoring of PH of the medium consist of sand+synthetic brine+ supercritical CO2 and sand+synthetic brine+ supercritical CO2. The experiments are conducted at pressures of 1100 and 1300 psi (CO2 at supercritical state) and temperatures ranged from 70-150. The results indicated that salinity of brine, pressure and temperature of the system directly affect the PH of solution and therefore formation of carbonates.
