Abstract
The main scope of the work related to the physical and dynamical processes associated with the injection of carbonated water in porous media. Carbonated water flooding is an alternative for traditional CO2 flooding. Both methods have the potential to recover any oil left behind after primary and secondary recovery while storing CO2 at the same time. The advantage of Carbonated Water flooding as compared to CO2 flooding is related to the high buoyancy of CO2 that results in gravity separation if the CO2 is not dissolved in water. This results in sub-optimal flooding of the reservoir and possible leakage of CO2.
