Quasi-Analytical Model of the Transient Behavior Pressure in an Oil Reservoir Made Up of Three Porous Media Considering the Fractional Time Derivative

open access: yesMathematical and Computational Applications, 2020
The present work proposes a new model to capture high heterogeneity of single phase flow in naturally fractured vuggy reservoirs. The model considers a three porous media reservoir; namely, fractured system, vugular system and matrix; the case of an ...

An efficient 3D cell-based discrete fracture-matrix flow model for digitally captured fracture networks

open access: yesInternational Journal of Coal Science & Technology, 2023
Complex hydraulic fracture networks are critical for enhancing permeability in unconventional reservoirs and mining industries. However, accurately simulating the fluid flow in realistic fracture networks (compared to the statistical fracture networks ...

Oil emulsions in naturally fractured Porous Media

open access: yesPetroleum, 2019
Most of the studies regarding the formation and stability of emulsions focus on the conditioning and management of crude oil on surface facilities. Since a great deal of the crude oil produced is in the form of stable emulsions, it is often claimed that ...

1923–2023: One Century since Formulation of the Effective Stress Principle, the Consolidation Theory and Fluid–Porous-Solid Interaction Models

open access: yesGeotechnics, 2022
In 1923, Karl Terzaghi developed the theory of soil consolidation in which he introduced the concept of effective stress (ES). Over the past century, various theoretical aspects have been unraveled regarding the Effective Stress Principle (ESP) and the ...

Numerical Simulation of Ferrofluid Flow in Heterogeneous and Fractured Porous Media Based on Finite Element Method

open access: yesFrontiers in Earth Science, 2021
Ferrofluid is a kind of magnetic fluid, the flow of which is controlled by an external magnetic field. Owing to this property, ferrofluid, as a new function material, has raised extensive concern in the oil industry.

A Darcy–Brinkman model of fractures in porous media

open access: yesJournal of Mathematical Analysis and Applications, 2017
For a fully-coupled Darcy-Stokes system describing the exchange of fluid and stress balance across the interface between a saturated porous medium and an open very narrow channel, the limiting problem is characterized as the width of the channel converges to zero. It is proven that the limit problem is a fully-coupled system of Darcy flow in the porous

Dual Virtual Element Methods for Discrete Fracture Matrix models

open access: yesOil & Gas Science and Technology, 2019
The accurate description of fluid flow and transport in fractured porous media is of paramount importance to capture the macroscopic behavior of an oil reservoir, a geothermal system, or a CO2 sequestration site, to name few applications.

A Coupled Darcy-Forchheimer Flow Model in Fractured Porous Media

open access: yesApplied Sciences, 2022
Aiming at nonlinear flow in fractured porous media, based on the finite volume method, the discrete equations of Darcy flow in porous and Forchheimer flow in fracture were derived, and a solution method for coupling flow is proposed. The flow solution by

Numerical Methods for Flow in Fractured Porous Media [PDF]

open access: yes, 2020
In this work we present the mathematical models for single-phase flow in fractured porous media. An overview of the most common approaches is considered, which includes continuous fracture models and discrete fracture models. For the latter, we discuss strategies that are developed in literature for its numerical solution mainly related to the ...
