Mathematical modeling of the long-term safety of carbon dioxide (CO2) storage in underground reservoirs

Industrial-scale injection of carbon dioxide (CO2) into geologic media will induce coupled processes of fluid flow, mass and heat transfer, and chemical and mechanical interactions between fluids and rocks. Mathematical models play a key role in all aspects of CO2 geologic storage, including site characterization, injection design, and performance monitoring and confirmation. The main challenges for modeling arise from couplings between different processes and the large range of space and time scales that must be considered. ...
