Thermodynamic and dynamic investigations are needed to study the sequestration capacity; CO₂ leakage; and environmental impacts. The results of the phase equilibrium and densities for CO₂-sequestration related subsystems obtained from the proposed thermodynamic model on the basis of statistical associating fluid theory equation of state were summarized. Based on the equilibrium thermodynamics; preliminary kinetics results were also illustrated with chemical potential gradient as the driving force. The proposed thermodynamic model is promising to represent phase equilibrium and thermodynamic properties for CO2-sequestration related systems; i.e. CO₂-(H₂S)-H₂O-ions (such as Na⁺; K⁺; Ca²⁺; Mg²⁺>; Cl^-; CO_{3 ^2-); and the implementation of thermodynamic model into kinetics model to adjust the non-ideality of species is vital because of the high pressure for the investigation of the sequestration process.}
