Geological Carbon Sequestration

The injected CO2 will acidify the resident brine, causing dissolution of minerals already in the reservoir, precipitation of secondary minerals, and changes of rock porosity and permeability. However, the fundamentals of geochemical and hydrological processes in this engineered geological system (e.g., thermodynamics and kinetics) are the same for natural processes such as diagenesis and ore deposit formation. Therefore, the studies of CO2-water-rock interactions for CCS have broad significance as well.

Global warming is another mega-environmental problem that faces our generation, in addition to the deteriorating water resource availability.
