A Continuous Projection-Based EDFM Model for Flow in Fractured Reservoirs

open access: yesSPE Journal, 2023
Summary Various researchers have evaluated different methods of modeling fractured reservoirs accurately and efficiently. Of these methods, the embedded discrete fracture model (EDFM) is one of the most popular because it does not require the mesh for the simulation domain to conform to the orientation of the natural fractures.

Robust implementations of the 3D-EDFM algorithm for reservoir simulation with complicated hydraulic fractures

Journal of Petroleum Science and Engineering, 2019
Abstract The geometry of the subsurface hydraulic fracture is complicated which deviates from the conventional single pan shape. It can be in multi-wing shape by the formation heterogeneity and/or 3D fracture networks caused by the pre-exising natural fractures.

Study of hydraulic fracturing in an anisotropic poroelastic medium via a hybrid EDFM-XFEM approach

Computers and Geotechnics, 2019
Abstract In this paper, we investigate the effects of poroelastic properties and permeability on hydraulic fracturing in an anisotropic medium. A hybrid approach combining the EDFM (embedded discrete fracture model) and XFEM (extended finite element method) is proposed. Fractures are embedded into a nonconforming grid used to determine the fluid flow

Fully-Coupled XFEM-EDFM Hybrid Model for Geomechanics and Flow in Fractured Reservoirs

open access: yesSPE Reservoir Simulation Conference, 2017
Abstract A mixed discretization approach is propsed to adequately resolve fracture system while accurately and efficiently modeling both flow and geomechanics. An extended finite element method (XFEM) is applied to approximate the geomechanics, and an embedded-discrete-fracture model (EDFM) is used to model the multiphase flow equations.
