Embedded Discrete Fracture Modeling as a Method to Upscale Permeability for Fractured Reservoirs [PDF]
Energies, 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 Online Generalized Multiscale Method for Embedded Discrete Fracture Model
AxiomsThis 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 ...

Local Embedded Discrete Fracture Model (LEDFM)
Advances 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
Energies, 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 ...
