Simulation results for the reference case considered in this study. 2D cross-sections of the (from top to bottom) pressure, temperature, CO2 mass fraction in the liquid, gas saturation, which is the mass fraction of exsolved CO2 in the pore fluids, and water density for the reference system after 1, 10, 50 and 100 years of carbonated water injection. Color bars indicating the range for each of the properties are displayed on right side of the plots. The dotted line marks the gas-charged water injection zone. This homogeneous hydrostatically pressured reference system assumes a 30 °C/km gradient, constant salinity of 35000 ppm (seawater), and water injection temperature of 40 °C. The water to CO2 injection mass ratio is 25:1.
