Previous studies have demonstrated that curvature-based capillary pressure and transducer-based capillary pressure agrees well for both imbibition and drainage at equilibrium, if only connected fluid interfaces were analyzed. In this study, we further demonstrate that as long as the system reaches equilibration, curvature-based capillary pressure are representative for both connected and...

After injecting $\rm{CO_2}$ into subsurface porous media for sequestration, $\rm{CO_2}$ may be trapped as continuous gas cap (structural trapping) [1] or dispersed ganglia (capillary trapping) [2]. The former can utilize local pore space more efficiently, while the latter has been well-recognized to be hydrodynamically more stable. After thousands of years, both gas cap and gas ganglia...

Ferrofluid, a stable suspension of superparamagnetic nanoparticles in a liquid carrier, can be manipulated. In an external magnetic field, either constant or evolving, magnetic forces drives the ferrofluid to deform and move, leading to the deformation of the fluid-ferrofluid interface. This has been extensively used in micro-electromechanical systems (MEMS) and here we are motivated to...

When a nonwetting fluid is forced to flow through an otherwise water-saturated porous solid medium (e.g. as occurs in geologic CO$_2$ sequestration and underground hydrogen storage projects), the movement and ultimate fate of that nonwetting phase is dictated by a range of physio-chemical interactions; including trapping within pore spaces due to capillarity, mobilization via viscous or...

Forced imbibition, which involves the invasion of a wetting fluid in natural rocks, plays an important role in efficient development of hydrocarbon resources and geological storage of carbon dioxide. However, the interface dynamics influenced by complex topology lead to non-wetting fluid trapping, particularly the underlying mechanisms under viscously unfavorable conditions remain unclear....

The heterogeneities of shale pore system are expressed in terms of the complex pore-fracture structure, different pore type and multi-scale pore size. Fluid transport mechanisms in shale nanopore space notably differ from that in conventional micro-scale porous media. Conventional core-scale multi-phase flow experiments are not applicable to shale because of the nanoscale pore size and the...

Wetting film can develop in the corners of pore structures during imbibition in a strongly wetting porous medium, which may significantly influence the two-phase flow dynamics. Due to the large difference in scales between main meniscus and corner film, accurate and efficient modeling of the dynamics of corner film remains elusive. In this work, we develop a novel two-pressure dynamic pore...

Our work aims to bridge length scales in immiscible multiphase flow simulation by connecting pore-scale and continuum-scale simulations through a novel validation framework. We employ Niessner and Hassnaizadeh's (2008) continuum-scale model for multiphase flow in porous media, combined with McClure et al.'s (2020) geometric equation of state, to provide a complete set of geometrical measures....

Geological carbon storage is a promising and feasible technique for greenhouse gas mitigation. To improve CO2 storage efficiency and develop monitoring techniques, it is important to know the CO2 flow behavior and capillary trapping mechanisms in subsurface rocks. Clay minerals, often found in sandstone, may exert a vital impact on the displacement process. However, the diversity of rock...

Modern 3D imaging provides a window to the microstructure of soil and rocks, and recent advances in experiments, simulation and data science can improve our understanding of how these materials influence the world around us. The Digital Rocks Portal (DRP, https://www.digitalrocksportal.org) is the first platform of its kind for porous media images’ management. It has an impressive collection...
