  • 2358: Effect of Calcium on the Formation and Ohio University

    Corrosion rates of casing steel are highly dependent on the formation of iron carbonate (FeCO3) in CO2/saline aquifer environments. Brine species such as Ca2+, which can form carbonate layers/scales, are very important in corrosion studies as they can compete with Fe2+ in the formation of carbonates. Therefore, there is
