A Pore-Scale Investigation of Residual Oil Distributions and Enhanced Oil Recovery Methods
Energies, 2019 Water flooding is an economic method commonly used in secondary recovery, but a large quantity of crude oil is still trapped in reservoirs after water flooding.

Elastoviscoplastic flows in porous media
Journal of Non-Newtonian Fluid Mechanics, 2018 We investigate the elastoviscoplastic flow through porous media by numerical simulations. We solve the Navier-Stokes equations combined with the elastoviscoplastic model proposed by Saramito for the stress tensor evolution. In this model, the material behaves as a viscoelastic solid when unyielded, and as a viscoelastic Oldroyd-B fluid for stresses ...

Research on Stress Sensitivity of Fractured Carbonate Reservoirs Based on CT Technology
Energies, 2017 Fracture aperture change under stress has long been considered as one of primary causes of stress sensitivity of fractured gas reservoirs. However, little is known about the evolution of the morphology of fracture apertures on flow property in loading ...

Adjoint-based topology optimization of filter structures for gas–particle systems
AIP Advances, 2021 Conventional filters for aerosol particle deposition consist of one or more filter layers, which are either woven or composed of tangled fibers. The quality of the separation results almost exclusively from the density of the fiber arrangement.

In Situ Deformation Analysis of a Fracture in Coal under Cyclic Loading and Unloading
Energies, 2021 The deformation analysis of fractures is vital for advantageous development of oil and gas fields, especially the coalbed methane (CBM) reservoir, since the change of fracture parameters can be directly evaluated through fracture deformation analysis ...

From Rayleigh-B\'enard convection to porous-media convection: how porosity affects heat transfer and flow structure [PDF]
, 2020 We perform a numerical study of the heat transfer and flow structure of Rayleigh-B\'enard (RB) convection in (in most cases regular) porous media, which are comprised of circular, solid obstacles located on a square lattice.

The Influence of Micro-Fractures on the Flow in Tight Oil Reservoirs Based on Pore-Network Models
Energies, 2019 In this paper, the influence of micro-fractures on the flow of tight reservoirs is studied on the microscopic scale. Three-dimensional digital cores of fractured tight sandstone with varying fracture apertures, lengths, and dip angles are constructed ...

Optimization of Non-Uniform Perforation Parameters for Multi-Cluster Fracturing
Energies, 2022 Stress shadowing affects the simultaneous propagation of fractures from multiple perforation clusters. Employing uniform perforation parameters for all clusters cause the unbalanced growth of fractures, which arouses the demand of optimizing non-uniform ...
