We present various numerical studies conducted with a novel pore-scale simulation technology called direct hydrodynamic (DHD) simulation that can be used to study multiphase flow at various scales ranging from individual pore-scale events to complex scenarios like capillary desaturation and relative permeability of digitized rock samples. DHD uses a diffuse interface description for fluid-fluid interfaces that is implemented via the density-functional approach applied to the hydrodynamics of complex systems. In addition to mass and momentum balance, a full thermodynamic energy balance is considered. Hence the simulator inherently takes into consideration multiphase and multicomponent behavior and is suited for nonisothermal cases which allows the handling of many physical phenomena including multiphase compositional flows with phase transitions, different types of fluid-rock and fluid-fluid interactions (e.g. wettability and adsorption), and various types of fluid rheology.
The DHD simulator is a research prototype optimized for high-performance computing (HPC) and applied to porous media systems. We demonstrate the utility of DHD to simulate two-phase flow displacement ranging from the classical “Lenormand” pore-scale displacement events and Roof’s snap-off criteria to more complex cooperative phenomena like capillary desaturation and relative permeability. The simulation results are benchmarked against experimental data in coreflooding, a 2D micromodel, and synchrotron-based X-ray microtomography experiments and provide good agreement.
