Uncertainty quantification in Discrete Fracture Network models: Stochastic fracture transmissivity
We consider flows in fractured media, described by Discrete Fracture Network (DFN) models. We perform an Uncertainty Quantification analysis, assuming the fractures’ transmissivity coefficients to be random variables. Two probability distributions (log-uniform and log-normal) are used within different laws that express the coefficients in terms of a family of independent stochastic variables; t...

متن کاملDeveloping a 3D stochastic discrete fracture network model for hydraulic analyses
Fluid flow in jointed rock mass with impermeable matrix is often controlled by joint properties, including aperture, orientation, spacing, persistence and etc. On the other hand, since the rock mass is made of heterogeneous and anisotropic natural materials, geometric properties of joints may have dispersed values. One of the most powerful methods for simulation of stochastic nature of geometri...
متن کاملImpact of Geological Characterization Uncertainties on Subsurface Flow Using Stochastic Discrete Fracture Network Models
A major issue to overcome when characterizing a deep fractured reservoir is that of data limitation due to accessibility and affordability. Moreover, the ability to map discontinuities in the rock with available geological and geophysical tools tends to decrease particularly as the scale of the discontinuity goes down. Geological characterization data include, but not limited to, measurements o...
متن کاملLimit theorems in discrete stochastic geometry
This overview surveys two general methods for establishing limit theorems for functionals in discrete stochastic geometry. The functionals of interest are linear statistics with the general representation ∑x∈X ξ (x,X ), where X is locally finite and where the interactions of x with respect to X , given by ξ (x,X ), exhibit spatial dependence. We focus on subadditive methods and stabilization me...
