Abstract Hydraulic fracturing is a well stimulation technique used to improve well productivity index; this technique has been widely applied in unconventional reservoirs (tight gas and tight oil). In this paper we describe a method we developed to couple hydraulic fracture modeling software with the embedded discrete fracture model (EDFM).

Monotone Embedded Discrete Fracture Method for the Two-Phase Flow Model
2020We propose an application of the new monotone embedded discrete fracture method (mEDFM) [13] to the two-phase flow model. The new method for modelling of flows in fractured media consists in coupling of the embedded discrete fracture method (EDFM) with the nonlinear monotone finite volume (FV) scheme with two-point flux approximation, which preserves ...

Abstract The wide implementation of hydraulic fracturing in shale reservoirs and the interactions among hydraulic fractures, natural fractures and the shale matrix have brought great challenge for reservoir studies using conventional finite-difference-based reservoir simulators. This work establishes a dynamic approach for the simulation

Abstract Accurate evaluation of recovery mechanisms in fractured reservoirs is challenging due to the large permeability contrast at the matrix-fracture interface. Dual Porosity-Dual Permeability (DPDK) models are typically used in field-scale simulations but can be biased by their use of idealized fracture networks and matrix-fracture ...

Abstract Optimizing multistage fractured horizontal wells (MFHW) can tap the full potential of tight oil reservoirs. Although recent studies have introduced various frameworks, most of the significant parameters for MFHW are not optimized simultaneously, which may lead to actual performance that is far below expected performance, especially in ...

Abstract A multiscale mimetic method is developed for the simulation of multiphase flow in fractured porous media in the context of an embedded discrete fracture model (EDFM). The EDFM constructs independent grids for matrix and fracture system. Therefore, it is an efficient and practical flow model as it avoids the complicated unstructured grid ...

The goal of this study is to develop a new model to simulate gas and water transport in shale nanopores and complex fractures. A new gas diffusivity equation was first derived to consider multiple important physical mechanisms such as gas desorption, gas slippage and diffusion, and non‐Darcy flow.

Abstract The discrete fracture-matrix (DFM) approaches based on conforming grids become popular for modeling fractured reservoirs in the last decade. However, the application of conforming DFMs at field scale is limited due to its prohibitive computational cost.

Development of an Embedded Discrete Fracture Model for Multi-Phase Flow in Fractured Reservoir
Applied Mechanics and Materials, 2014Considering the discontinuities of the phase saturations and pressure gradients at the matrix-fracture interface, a modified algorithm for the embedded discrete fracture model is proposed. In this algorithm, the exchange rate between fracture and matrix on two sides of the interface are calculated separately.
