Homogenization of two fluid flow in porous media. [PDF]

open access: yesProc Math Phys Eng Sci, 2015
The macroscopic behavior of air and water in porous media is often approximated using Richards’ equation for the fluid saturation and pressure. This equation is parametrized by the hydraulic conductivity and water release curve.

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 ...

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.

SPH Simulation of Interior and Exterior Flow Field Characteristics of Porous Media [PDF]

open access: yes, 2020
At the present time, one of the most relevant challenges in marine and ocean engineering and practice is the development of a mathematical modeling that can accurately replicate the interaction of water waves with porous coastal structures. Over the last

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.

Reconstruction of 3D multi-mineral shale digital rock from a 2D image based on multi-point statistics

open access: yesFrontiers in Earth Science, 2023
Introduction: Shale oil and gas reservoirs contain a variety of inorganic and organic pores that differ significantly from conventional reservoirs, making traditional experiments ineffective.

Direct Visualization of Nanoscale Salt Precipitation and Dissolution Dynamics during CO2 Injection

open access: yesEnergies, 2022
CO2 injection to enhance shale oil recovery provides a win-win solution to meet the global fuel shortage and realize ultimate carbon neutrality. When shale reservoirs contain high salinity water, CO2 injection can result in salt precipitation to block ...

Fates of Emitted Particles Depending on Mask Wearing Using an Approach Validated Across Spatial Scales

open access: yesGlobal Challenges, 2023
The spread of emitted potentially virus‐laden aerosol particles is known to be highly dependent on whether a mask is worn by an infected person and on the emission scenario, i.e., whether the person is coughing, speaking, or breathing.

Analysis of the Brinkman equation as a model for flow in porous media [PDF]

open access: yes, 1987
The fundamental solution or Green's function for flow in porous media is determined using Stokesian dynamics, a molecular-dynamics-like simulation method capable of describing the motions and forces of hydrodynamically interacting particles in Stokes ...
