Simulation of Coupled Processes of Flow, Transport and Storage of CO2 in Saline Aquifers
Performer: Colorado School of Mines
Project No: FE0000988
This four-year project — performed by the Colorado School of Mines in partnership with Lawrence Berkeley National Laboratory (LBNL) — is developing a comprehensive reservoir simulator for modeling non-isothermal multiphase flow and transport of CO2 in saline aquifers under varying temperature and pressure conditions. The project focuses on saline aquifers because these formations have the largest potential capacity for CO2 storage. The simulator models the complex geology of these formations, including heterogeneity, anisotropy, fractures, and faults. The simulator also models geochemical and geomechanical processes that would occur during geologic storage of CO2 . It uses parallel computation methods to allow rapid and efficient modeling assessment of CO2 injection strategies and long-term prediction of geologic storage system behavior and safety. The experimental plan will expand upon past experience and approaches with multiphase flow experiments at various scales to assess CO2 geologic storage. Small-scale test experiments will be used to identify the fundamental processes in homogeneous systems and test the ability of the macroscopic scale models to capture the capillary and dissolution trapping processes in the presence of pore-scale heterogeneities. The model simulations will support the evaluation of geologic storage mechanisms as a viable technique for reducing atmospheric CO2 emissions.
