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 ...

Upscaling multi-component two-phase flow in porous media with partitioning coefficient [PDF]
, 2011 This paper deals with the upscaling of multicomponents two-phase flow in porous media. In this paper, chemical potential equilibrium at the interface between both phases is assumed to be described by a linear partitioning relationship such as Raoult or ...

Reducing indoor particle exposure using mobile air purifiers—Experimental and numerical analysis
AIP Advances, 2021 Aerosol particles are one of the main routes of transmission of COVID-19. Mobile air purifiers are used to reduce the risk of infection indoors. We focus on an air purifier that generates a defined volumetric air flow through a highly efficient filter ...

MODELING WELLS IN POROUS MEDIA FLOW
Mathematical Models and Methods in Applied Sciences, 2000 In this paper, we prove the existence of weak solutions for mathematical models of miscible and immiscible flow through porous medium. An important difficulty comes from the modelization of the wells, which does not allow us to use classical variational formulations of the equations.

Coupling of two-phase flow in fractured-vuggy reservoir with filling medium
Open Physics, 2017 Caves in fractured-vuggy reservoir usually contain lots of filling medium, so the two-phase flow in formations is the coupling of free flow and porous flow, and that usually leads to low oil recovery.
