... of the fracturing pattern is required. DFN models are statistical models which define the density of fractures having given geometrical properties (size and orientation) and which include an intrinsic variability term. One of the main challenging task is to combine all available data. Data remain sparse and scarce...

... properties and the complete fracture network system through its relevant geometrical properties. We show that the resulting effective properties depend on stress regime, fracture size and orientation. We finally apply the model to site statistical DFN models defined from investigations led in Scandinavia...

Using Monte Carlo technique, stochastic DFN models were generated with a large number of realizations with the same fracture density and different aperture patterns when distributed...

... and Kjellbert, 1990). Stochastic continuum models can include a variety of flow and mass transport mechanisms, and are numerically tractable at the scale of the Aspo site. Another alternative is to use discrete fracture network (DFN) models. DFN models (Figure 2) idealize the hydraulically significant fractures...
