... Abstract Projection-based embedded discrete fracture models (pEDFMs) are proven effective for modeling flow barrier effects of high-conductivity or impermeable fractures. However, local grid refinements are still needed to improve the accuracy of simulation in flow areas near fractures...

... the integrally embedded discrete fracture model (IEDFM). This model considers a more improved pressure distribution assumption in the vicinity of fractures compared to traditional EDFM and calculates the matrix-fracture transmissibility semi-analytically. Another advantage of the IEDFM is the capability...

..., at the same time, it remains accurate in presence of complex fluid physics and heterogeneous rock properties. The embedded discrete fracture model is employed to accurately represent fractures without the necessity of unstructured complex grids. On the fine-scale system, FG-ADM introduces a multi-resolution...

... parameters can be fully coupled with geomechanical model. Embedded discrete fracture model was also improved to be compatible with the geomechanical coupling. Both of TOUGH2-THM and modified EDFM were validated for further application. A geothermal reservoir simulation is conducted by the newly developed...

... modeling of production in fractured systems requires including the dynamic behavior of fractures into a discrete fracture model. We have incorporated the dynamic behavior of fractures into an embedded discrete fracture model, called EDFM. The coupled model allows inclusion of the impact of stress regime...

..., it is neither practical nor advantageous to model a large number of pre-existing fractures with a discrete fracture model. Therefore, an appropriate approach to model production from low-permeability reservoirs is to perform discrete fracture modeling for hydraulic fractures and employ a dual continuum approach...

... Abstract Fractured reservoir permeability, water-breakthrough and hydrocarbon recovery cannot be extrapolated from experimental data obtained on cores. Instead computer simulations allow these processes to be studied in discrete- fracture models at an intermediate scale. We represent...

... Abstract A simplified discrete fracture model suitable for use with general purpose reservoir simulators is presented. The model handles both two and three-dimensional systems and includes fracture-fracture, matrix-fracture and matrix-matrix connections. The formulation applies an unstructured...

... Abstract Results from a new multiphase discrete fracture model are compared to simulation results using a variety of homogenization methods. A 2-D random fracture network is used as an example. The discrete-fracture model has been developed as an alternative to the dual porosity models...
