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 ...

Spatial Fractional Darcy’s Law on the Diffusion Equation with a Fractional Time Derivative in Single-Porosity Naturally Fractured Reservoirs

open access: yesEnergies, 2022
Due to the complexity imposed by all the attributes of the fracture network of many naturally fractured reservoirs, it has been observed that fluid flow does not necessarily represent a normal diffusion, i.e., Darcy’s law.

Effect of magnetic field on imbibition phenomenon in fluid flow through fractured porous media with different porous material

open access: yesNonlinear Engineering, 2019
In this paper, the counter-current Imbibition phenomenon is considered in a fractured heterogeneous porous medium with the consideration of different porous materials like fine sand, volcanic sand and glass beads and magnetic field effect.

Azimuthal Attenuation Elastic Impedance Inversion for Fluid and Fracture Characterization Based on Modified Linear-Slip Theory

open access: yesGeofluids, 2019
The seismic attenuation should be considered while accounting for the effect of anisotropy on the seismic wave propagating through a saturated fractured porous medium.

Fractal model and Lattice Boltzmann Method for Characterization of Non-Darcy Flow in Rough Fractures. [PDF]

open access: yes, 2017
The irregular morphology of single rock fracture significantly influences subsurface fluid flow and gives rise to a complex and unsteady flow state that typically cannot be appropriately described using simple laws.

Convergence Analysis of a Numerical Method for a Fractional Model of Fluid Flow in Fractured Porous Media

open access: yesMathematics, 2021
The present paper is devoted to the construction and study of numerical methods for solving an initial boundary value problem for a differential equation containing several terms with fractional time derivatives in the sense of Caputo.

Characterisation of the transmissivity field of a fractured and karstic aquifer, Southern France [PDF]

open access: yes, 2015
International audienceGeological and hydrological data collected at the Terrieu experimental site north of Montpellier, in a confined carbonate aquifer indicates that both fracture clusters and a major bedding plane form the main flow paths of this ...

Quantitative visualization of two-phase flow in a fractured porous medium

open access: yesWater Resources Research, 2023
Two-phase fluid flow in fractured porous media impacts many natural and industrial processes but our understanding of flow dynamics in these systems is constrained by difficulties measuring the flow in the interacting fracture and porous media. We present a novel experimental system that allows quantitative visualization of the air and water phases in ...

Hydrogeological site characterization of marly-silici-calcareous rocks through surveys of discontinuities and pumping tests

open access: yesAcque Sotterranee, 2012
One of the challenges in the characterization of fractured aquifers is to define whether the approximation to a porous medium is valid or not. In this context, the present study concerns the hydrogeological characterization of a small area constituted by

A multiscale flux basis for mortar mixed discretizations of reduced Darcy-Forchheimer fracture models [PDF]

open access: yes, 2018
In this paper, a multiscale flux basis algorithm is developed to efficiently solve a flow problem in fractured porous media. Here, we take into account a mixed-dimensional setting of the discrete fracture matrix model, where the fracture network is ...
