An Integrally Embedded Discrete Fracture Model for Flow Simulation in Anisotropic Formations
Energies, 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 ...
