Contributions on numerical modelling and risk assessment of CO2 injection processes on carboniferous formations

There are several ways of mitigating GHG emissions to the atmosphere, however, the storage of large quantities of carbon in geological formations is one of the most effective and with visible results today. Carbon dioxide Capture and Storage (CCS) is a process consisting in the separation of CO2 from industrial and energy-related sources (He et al., 2011). Figure 1 gives a schematic diagram of possible CCS systems showing the sources, for which CCS might be relevant, and the transport and storage of CO2 options.
