CO2 Sequestration
Convener: Hamdi Tchelepi, Stanford University
Numerical simulation is expected to play an important role in the planning, development, and monitoring of practical subsurface CO2 sequestration projects. Several important challenges must be met before a simulation-based approach can be used with confidence. Here, we solicit papers that describe experimental and numerical approaches for exploring the multiscale physics associated with subsurface CO2 sequestration processes, from the pore scale to the field, with emphasis on physically based models that bridge the scales in a coherent and consistent mathematical and numerical framework. This includes areas related to (1) static and dynamic data integration of highly detailed models, (2) quantification of prediction uncertainty due to missing information, (3) small and large-scale experiments targeted at the CO2-brine system, (4) multiscale numerical formulations suited for accurate modeling of the post-injection period, where buoyancy, diffusion, and dissolution are the dominant mechanics for flow and transport.
