文摘

Large-scale simulation of multi-phase flow using the ADGPRS/GFLASH software is presented. Aqueous electrolyte solutions are modeled using the GHC equation. Salt precipitation/dissolution are modeled using combined chemical/phase equilibrium. Sequestration by residual, dissolution and mineral trapping are illustrated. Three examples demonstrate that ADGPRS/GFLASH captures key physics of CO2 sequestration.
