Abstract

Summary

This paper explores the relationship of permeability to fracture aperature, density and mineralisation in synthetic dual porosity media. Fluid flow is simulated using the Lattice-Boltzmann method which allows for detailed fracture geometries to considered in 3D. The geometry of the matrix part of the media is built using a Voronoi based approach similar to the work in 2D by .

Stress sensitivity can be an important phenomena in dual porosity media. Reductions in reservoir pressure as production proceeds cause decreases in porosity and consequentially decreases in permeability. This effect is explored by considering the impact of fracture compressibility.

While it is not anticipated that full field modelling at this scale will be undertaken in the foreeable future, modelling such as this allows insight to defining appropriate REVs and into upscaling.
