We will consider the storage of CO2 several kilometers beneath the surface in generic aquifers to advance our fundamental understanding of various mechanisms that are crucial for long term sequestration of CO2 in saline aquifers, which contain highly mineralized brines. The three most important mechanisms for the sequestration of carbon dioxide in saline reservoirs are trapping, dissolution in water or brine and, mineral sequestration. We will study the fundamental physics behind these mechanisms and their relationship with sequestration via multi-phase numerical simulations using the TOUGH2/TOUGHREACT Code.
