An Integrally Embedded Discrete Fracture Model for Flow Simulation in Anisotropic Formations [PDF]

open access: yesEnergies, 2020
The embedded discrete fracture model (EDFM), among different flow simulation models, achieves a good balance between efficiency and accuracy. In the EDFM, micro-scale fractures that cannot be characterized individually need to be homogenized into the ...

Simulation and evaluation for acid fracturing of carbonate reservoirs based on embedded discrete fracture model

open access: yesNatural Gas Industry B, 2021
Acid fracturing is an important means of reservoir stimulation, whose purpose is to form an incompletely closed acid-etched fracture as the flow channel for oil and gas during production.

Embedded Discrete Fracture Modeling as a Method to Upscale Permeability for Fractured Reservoirs [PDF]

open access: yesEnergies, 2019
Fractured reservoirs are distributed widely over the world, and describing fluid flow in fractures is an important and challenging topic in research. Discrete fracture modeling (DFM) and equivalent continuum modeling are two principal methods used to ...

An Improved Embedded Discrete Fracture Model with Fracture Growth for Water-Induced Fracture Simulation in Low Permeability Reservoirs [PDF]

open access: yesLithosphere, 2022
Water injection is often used to supply formation energy in low permeability reservoirs. A lot of field data shows that fractures nearby the wellbores may extend hundreds of meters because of the poor injectability which is called water-induced fractures.

Productivity simulation of hydraulically fractured wells based on hybrid local grid refinement and embedded discrete fracture model

open access: yesPetroleum Exploration and Development, 2020
Using current Embedded Discrete Fracture Models (EDFM) to predict the productivity of fractured wells has some drawbacks, such as not supporting corner grid, low precision in the near wellbore zone, and disregarding the heterogeneity of conductivity ...

An Online Generalized Multiscale Method for Embedded Discrete Fracture Model

open access: yesAxioms
This study concerns an online generalized multiscale method for flow in fractured porous media that is based on an embedded discrete fracture model. We first convert a two-point flux-approximation scheme into an equivalent discrete weak formulation that ...

Projection-based Embedded Discrete Fracture Model (pEDFM)

open access: yesAdvances in Water Resources, 2017
This work presents a new discrete fracture model, namely the Projection-based Embedded Discrete Fracture Model (pEDFM). Similar to the existing EDFM approach, pEDFM constructs independent grids for the matrix and fracture domains, and delivers strictly conservative velocity fields.

Local Embedded Discrete Fracture Model (LEDFM)

open access: yesAdvances in Water Resources, 2023
The study of flow in fractured porous media is a key ingredient for many geoscience applications, such as reservoir management and geothermal energy production. Modelling and simulation of these highly heterogeneous and geometrically complex systems require the adoption of non-standard numerical schemes. The Embedded Discrete Fracture Model (EDFM) is a

Numerical Simulation of Embedded Discrete-Fracture Seepage in Deep Carbonate Gas Reservoir

open access: yesEnergies, 2022
Existing fractured gas reservoir development techniques are mainly based on dual medium numerical-simulation models, which can, to a certain extent, effectively simulate natural fractures with high fracture density; however, these models have some ...
