Microtomographic imaging techniques and advanced numerical simulations are combined by digital rock physics (DRP) to obtain effective physical material properties. The numerical results are typically used to complement laboratory investigations with

Three-dimensional flow characterization in a joint with plumose pattern

Autor: Christophe Pascal, Benoit Nigon, Andreas Englert

Publikováno v: Hydrogeology Journal. 27:87-99

This work numerically simulates fracture flow in natural fractures, specifically in a joint with plumose pattern. A natural fracture surface, previously measured in the field using LiDAR scanning, was used to rebuild an open fracture geometry, assumi

Multiscale Characterization of Joint Surface Roughness

Autor: Benoit Nigon, Christophe Pascal, Andreas Englert, Aline Saintot

Publikováno v: Journal of Geophysical Research: Solid Earth. 122:9714-9728

Recent studies provided detailed characterizations of fault (i.e. shear fracture) roughness at different length scales. Similar investigation for joints (i.e. tensile fractures) are seldom and not as detailed. The present study aims at characterizing

International audience; In fractured media, solute transport is controlled by advection in open and connected fractures and by matrix diffusion that may be enhanced by chemical weathering of the fracture walls. These phenomena may lead to non-Fickian
