Shales are ubiquitous rocks in sedimentary basins, where their low permeability makes
them efficient seals for conventional oil and gas reservoirs and underground waste storage …

Argillaceous formations generally act as aquitards because of their low hydraulic
conductivities. This property, together with the large retention capacity of clays for cationic …

Within the framework of feasibility studies for a reversible, deep geological repository of high-
and intermediate-level long-lived radioactive waste (HLW, IL-LLW), the French National …

We used Broad-Ion-Beam polishing in combination with Scanning Electron Microscopy to
study the microstructure and porosity in the Shaly facies of Opalinus Clay (northern …

This paper is devoted to the study of the Thermo-Hydro-Mechanical (THM) responses of a
porous rock with low permeability under thermal loading in the context of deep geological …

The mesostructure (millimeter to micrometer scale) of clay‐rich sedimentary rocks is
generally characterized by a connected fine‐grained clay matrix embedding coarser …

A combination of Broad-Ion-Beam (BIB) polishing and Scanning Electron Microscopy (SEM)
has been used to study qualitatively and quantitatively the microstructure of Opalinus Clay in …

Carbon capture and storage (CCS) is likely to be a critical technology to achieve large
reductions in global carbon emissions over the next century. Research on the subsurface …

Anisotropy in clay-rich sedimentary rocks is receiving increasing attention. Seismic
anisotropy is essential in the prospecting for petroleum deposits. Anisotropy of diffusion has …

In the context of radioactive waste disposal, an underground research laboratory (URL) is a
facility in which experiments are conducted to demonstrate the feasibility of constructing and …
