Conference Paper
Full-text available
Intersections between the fractures of a network defines its connectivity and constitute a key component both for the hydrogeological and mechanical behavior of fractured rock masses. Existing analyses of 2D field trace maps provide a framework for analyzing 2D fracture intersection distributions. In this paper, we perform a complete analysis of 3D...

The realism of Discrete Fracture Network (DFN) models relies on the spatial organization of fractures, which is not issued by purely stochastic DFN models. In this study, we introduce correlations between fractures by enhancing the genetic model (UFM) of Davy et al. [1] based on simplified concepts of nucleation, growth and arrest with hierarchical...
Thesis
Full-text available
Les fractures sont des structures géologiques omniprésentes contrôlant les propriétés hydrauliques et mécaniques des roches. La modélisation numérique des réseaux de fractures constitue donc une étape indispensable pour la simulation du comportement physique des massifs fracturés, dans de nombreuses applications industrielles telles que le stockage...

DFN.lab is a modular computational suite to deal with three-dimensional discrete fracture networks (DFN) models from DFN generation to simulation and analysis of connectivity, flow, mechanical and transport properties. DFN.lab is developed by the Fractory, a joint laboratory between the French institute for scientific research (CNRS), the universit...
Article
Full-text available
This paper presents analytical solutions to estimate at any scale the fracture density variability associated to stochastic Discrete Fracture Networks. These analytical solutions are based upon the assumption that each fracture in the network is an independent event. Analytical solutions are developed for any kind of fracture density indicators. Th...

Project
This project aims to quantify the variability associated to 3D fracture densities. Three-dimensional mean fracture densities can be estimated from borehole p10 or outcrops p21 measurements, and stereological rules. What about the associated varviability ?
Project
A common platform to assemble various efforts to address to elusive essence of fracturing in rock, focussing on Dicrete Fracture Modelling (DFN)
