Short description: Three-dimensional systems will be reconstructed from available information, based on the use of serial thin sections for porous media and on the use of trace maps for fracture networks. Experimental measurements will be performed on porous medium samples and compared to the numerical predictions. Fracture connectivity and scaling rules will be analyzed using a 3D fracture model generator that reproduces the main geometrical and statistical properties of natural fracture systems (including a power-law length distribution, and the spatial correlation). Special emphasis will be placed on the clustering properties of fractures. Statistical models of the detailed structure in major fault zones will be used to examine the relationships between fault density, fault rock hydraulic properties, fault connectivity and bulk rock permeability. These analyses will be used as a step towards converting modelled strain fields to bulk rock hydraulic properties. A model will be applied and further developed to predict the spatial variation in brittle deformation in the vicinity of major faults. This model will aid analysis of the type and intensity of small scale fracturing, and help to evaluate effective fractured rock hydraulic properties around major faults. A numerical model will be developed to account for chemically-assisted crack growth in saline and non-saline environments, and to account for poroelasticity effects.
