CO2 injection impairment due to halite precipitation

The injection of dry supercritical CO2 into brine aquifers has the potential to dry saline formation waters, due to evaporation effects [1], leading to severe increases in salinity and salt precipitation. This can significantly impair injection rates, as has been noted in gas-storage reservoirs. [2] This is of interest for CO2 storage in saline aquifers. An injection impairment study was performed for the CO2SINK Project, a European Union...
