PORE 2-8.1: Multiscale modeling and simulation of fractured porous rocks: Simulation science for sustainable geosciences, from CO2 and H2 storage to geothermal energy

*This course was previously listed as PORE 3-X

The increasing demand for accurate and efficient simulation of multiphase flow, heat transfer and mechanics in subsurface formations motivates the development of advanced computational methods which are not only accurate but also amenable to uncertainty quantification. The non-linear, heterogeneous, uncertain, dynamic and coupled nature of the mathematical formulations make such developments challenging, yet possible if a multiscale methodology is properly devised for the components of the coupled system.
