Simulation of the impact of SO2 co-injected with CO2 on the reservoir- rock reactivity

An important aspect in CO2 storage in geological media is the quality requirements put on the gases to be stored in terms of risk management. This study investigates and compares, through reactive transport modelling, the potential short-term (5y) reactivity of CO2 gas streams ˗ pure or containing ancillary gaseous compounds (SO2 : 0˗1.5% Wt) ˗ with the reservoir-rock of a limestone aquifer at 75°C. The modelling approach simulates the...
