Abstract

Summary

This paper presents a workflow for deriving bulk permeability of a domain containing high permeable fracture networks within low permeable matrix. The following workflow is inspired from fracture networks that have been mapped and analysed from a pavement gallery of the Whitby Mudstone. Based on this work the statistical data for fracture aperture, fracture length, fracture frequency, and fracture orientation have been employed to generate generic discrete fracture networks (DFN) of different scale. These DFNs have been loaded into a numerical software package based on the eXtended Finite Element Method and embedded into a homogeneous poroelastic medium. The determined bulk permeability of fractures and matrix can be used for upscaling issues in order to avoid simulating a great amount of small scale fractures in a large-scale fluid flow simulations as for example common in the geothermal or oil and gas industry.
