Fract_004 Homogenisation of Flow Properties in Jointed Model

Contents

Introduction

The aim of this tutorial example is to recover effective flow permeability based on a target solution of a discrete model using ParaGeoInv, as illustrated below. We demonstrate homogenisation using two methods, i.e., ubiquitous embedded fracture (UEF) approach and spatially embedded fracture (SEF) approach. The latter coincides with the spatial distribution of fractures in the discrete model. Overview of ParaGeoInv and the inverse analysis and data structures are provided in ParaGeoInv Reference Manual. Undertaking of GeoInv Tutorial Examples prior to the present example is also recommended.

The following table shows the fluid volume and flow rate on "west" and "north" geometry sets as target solution. The reference solution used to generate the target measurements is also provided to allow for comparisons. The data and results are in Fract_004\Reference Solution.

Geometry Set	Fluid Volume (m3)	Fluid Volume Flow Rate (m3/Ma)
west	244.439	488.878
north	295.113	590.226
