A Coupled XFEM-EDFM Numerical Model For Hydraulic Fracture Propagation

Proceedings, 2018
Summary Fracture propagation (FP) occurs in various applications including hydraulic fracturing, underground disposal of liquid waste, in-situ stress estimation, and the failure of dams due to underwater cracks. This work develops a numerical model of the hydraulic fracturing process that is widely applied to the extraction of natural gas from shale ...

XFEM-EDFM-MINC for Coupled Geomechanics and Flow in Fractured Reservoirs

Proceedings, 2016
Unconventional reservoirs are often naturally and hydraulically fractured with characteristically small pores and low permeability within the matrix. The underlying fracture networks can have a wide range of length scales and complex geometries. While hydraulic fractures may be propped, natural fractures are predominantly supported by pore pressure.

An Integrated EDFM+DPDK Hybrid Workflow for Hierarchical Treatment of Fractures in Practical Field Studies

SPE Western Regional Meeting, 2022
Abstract Natural fracture systems comprise numerous small features and relatively few large ones. At field scale, it is impractical to treat all fractures explicitly. We represent the largest fractures via Embedded Discrete Fracture Modeling (EDFM) and account for smaller ones using a dual-porosity, dual-permeability (DPDK) idealized ...

Using Embedded Discrete Fracture Models (EDFMs) to Simulate Realistic Fluid Flow Problems

Proceedings, 2013
A large amount of world’s hydrocarbon reserves lies in reservoirs where one of the key features is the presence of a system of fractures spanning different length scales. Fractures may provide ways to drain the matrix, but they also drive gas and water towards wells.

Parameterization of embedded discrete fracture models (EDFM) for efficient history matching of fractured reservoirs

Journal of Petroleum Science and Engineering, 2021
Abstract Embedded Discrete Fracture Model (EDFM) is a promising approach to describe the reservoirs with fractures. Conventional streamline-based inversion method has been limited to the dual-porosity models where the natural fractures are modeled implicitly and flow between matrix blocks is not accounted for.

A Novel Technique on Microseismic - EDFM Fracture Modeling and Calibration for Complex Fractures in Unconventional Reservoirs

International Petroleum Technology Conference, 2022
Abstract Hydraulic fracture models are useful mechanisms to understand reservoir properties and performance in unconventional reservoirs. The inclusion of field measurements can further refine hydraulic fracture models by providing key information to optimize field development planning.

A Fast EDFM Method for Production Simulation of Complex Fractures in Naturally Fractured Reservoirs

SPE/AAPG Eastern Regional Meeting, 2018
Abstract Natural fractures are the main producibility factor in the weathered granite reservoirs (basement rock) and volcanic-rock reservoirs. Production practices show that these reservoirs could have high production rate, but the difference of well productivity between single wells is obvious.

Coupling EDFM-AI and ESMDA for Dynamic Unconventional Reservoir Characterizations

ADIPEC
Abstract Hydraulic fracturing is the key enabling technology for the economic development of unconventional reservoirs, where well productivity depends on the creation of an extensive, conductive fracture network. Accurate characterization of effective fracture geometry and reservoir properties is essential for predicting well ...

Modeling Interwell Interference Due to Complex Fracture Hits in Eagle Ford Using EDFM

International Petroleum Technology Conference, 2019
Abstract Shale field operators have vested interest in optimal spacing of infill wells and further fracture optimization, which ideally should have as little interference with the existing wells as possible. Although proper modeling has been employed to show the existence of well interference, few models have forecasted the impact of ...

An EDFM-MINC Model for Capturing Near-Fracture Physics in Unconventional Reservoirs

SPE Reservoir Simulation Conference
Abstract The Embedded Discrete Fracture Model (EDFM) has been widely used to simulate fluid flow and transport in unconventional reservoirs, such as shale-gas and tight oil formations. However, EDFM struggles to capture early-time matrix-fracture interactions when using coarse grids due to the extremely low matrix permeability in these ...
