Abstract:

Increasing attention has been paid to multiphase flow in subsurface geological porous media due to issues related with enhanced oil recovery, geothermal technology, unconventional oil/gas reservoirs, geological carbon sequestration, and subsurface storage of hydrogen. In this talk, we first review the difficulties engineers face in numerical simulation of multiphase flow in geological porous media, especially the intertwined challenges below: Strong multiscale geological heterogeneity and fracture–matrix interactions complicate medium representation; nonlinear physics including capillary–viscous competition, wettability hysteresis, and THMC (Thermal-Hydrological-Mechanical-Chemical) coupling raise modeling/numerical difficulty; sharp saturation fronts cause numerical diffusion and instability while strong nonlinearity hinders convergence; large 3D field models incur prohibitive computational cost; scarce measurements, upscaling errors, and parameter uncertainty reduce reliability and validation, etc. By using incompressible immiscible two-phase flow as an example, we then present our recent work in designing novel stable and efficient numerical schemes attempting to address some of the challenges above.
