In-situ characterization of capillary pressure during three-phase flow in porous media [PDF]

open access: yesE3S Web of Conferences, 2023
We characterize the pore-scale fluid distributions, phase connectivity, and local capillary pressures during three-phase flow in a water-wet Berea sandstone sample.

Dynamic pore-scale modeling of residual fluid configurations in disordered porous media [PDF]

open access: yesE3S Web of Conferences, 2023
Fluid trapping in porous media is important in many subsurface flow processes such as enhanced oil recovery and geological sequestration of carbon dioxide.

Semi-Implicit Finite Volume Procedure for Compositional Subsurface Flow Simulation in Highly Anisotropic Porous Media

open access: yesFluids, 2021
Subsurface multiphase flow in porous media simulation is extensively used in many disciplines. Large meshes with non-orthogonalities (e.g., corner point geometries) and full tensor highly anisotropy ratios are usually required for subsurface flow ...

Computation of the Permeability Tensor of Non-Periodic Anisotropic Porous Media from 3D Images [PDF]

open access: yes, 2022
The direct proportionality between the flow rate and the pressure gradient of creeping flows was experimentally discovered by H. Darcy in the 19th century and theoretically justified a couple of decades ago using upscaling methods such as volume ...

Percolativity of Porous Media

open access: yesTransport in Porous Media, 2022
AbstractConnectivity and connectedness are nonadditive geometric functionals on the set of pore scale structures. They determine transport of mass, volume or momentum in porous media, because without connectivity there cannot be transport. Percolativity of porous media is introduced here as a geometric descriptor of connectivity, that can be computed ...

Numerical analysis of water-alternating-CO2 flooding for CO2-EOR and storage projects in residual oil zones

open access: yesInternational Journal of Coal Science & Technology, 2023
Residual oil zones (ROZs) have high residual oil saturation, which can be produced using CO2 miscible flooding. At the same time, these zones are good candidates for CO2 sequestration.

Drying of Porous Media [PDF]

open access: yesTransport in Porous Media, 2015
Drying of porous media is part of our daily experience, yet this common process is central to many environmental and engineering applications ranging from soil evaporation affecting hydrological water balance and climatic processes, to the drying of food and building materials, and driving plant life through transpiration.

Numerical Study of the Effect of a Power-law Fluid Flow Structures on Levels of Mixing in a Taylor Couette Configuration [PDF]

open access: yesJournal of Applied Fluid Mechanics, 2023
This work is a numerical study on the effects of the flow structures of the power-law fluid between two concentric cylinders with an upward laminar axial flow on levels of mixing and mean residence time through the Taylor Couette system.

Numerical Study of Elasto-Plastic Hydraulic Fracture Propagation in Deep Reservoirs Using a Hybrid EDFM–XFEM Method

open access: yesEnergies, 2021
Rock yielding may well take place during hydraulic fracturing in deep reservoirs. The prevailing models based on the linear elastic fracture mechanics (LEFM) are incapable of describing the evolution process of hydraulic fractures accurately.
