Advanced geotechnical engineering applications, such as shale gas extraction, CO2 geological sequestration, and geological radioactive waste storage, often involve various types of shales located at significant depths. Shales exhibit mechanical properties ...
Oxford2024Hydro-Mechanical Characterization of a Shale by Unusually High-Pressure Oedometric Tests
Alessio Ferrari, Eleonora Crisci
The note presents selected results of an experimental campaign conducted with the aim to investigate the hydro-mechanical behaviour of a shale recovered at a depth of about 900 m below the ground. High-pressure oedometric tests were performed to investigat ...
Wei Wu, Universität für Bodenkultur2023Insights into the interaction of a shale with CO2
Lyesse Laloui, Eleni Stavropoulou
Caprock formations, such as shales, play a key role in safe underground CO2 storage since they serve as a hydromechanical barrier that prevents migration of the injected CO2 to the surface. While their hydromechanical response is important to ensure their ...
2022Effect of the mineralogical composition on the elastoplastic hydromechanical response of Opalinus Clay shale
Lyesse Laloui, Alessio Ferrari, Eleonora Crisci
Opalinus Clay is the shale currently under investigation as the host formation for geological radioactive waste disposal in Switzerland. Its hydromechanical response has been widely studied, and the experimental results show a range of values whose dispers ...

The testing procedure and results on saturated samples of Opalinus Clay in the work of Schuster et al. (Rock Mech Rock Eng https://doi.org/10.1007/ s00603-021-02474-3, 2021) were conducted and presented using strain rates two to four orders of magnitudes h ...
SPRINGER WIEN2021Experimental assessment of the hydro-mechanical behaviour of a shale caprock during CO2 injection
Lyesse Laloui, Alessio Ferrari, Eleni Stavropoulou, Alberto Minardi, Taeheon Kim
The presented experimental study focuses on the hydro-mechanical characterisation of a shale caprock (Opalinus Clay) in contact with carbon dioxide. The objective of this paper, consists in the evaluation of the material's sealing capacity in terms of entr ...
2021Developing a high capacity axis translation apparatus for gas shale testing
Lyesse Laloui, Alessio Ferrari, Jinwoo Kim
Gas shales are usually partially saturated due to hydrocarbon generation and often have a low in-situ degree of saturation less than 40 %. During stimulation, substantial fluid imbibition into the formation occurs due to high suction. Recent research on th ...
EDP Sciences2020Numerical investigation on water exchange of shale samples
Alessio Ferrari, Sara Incollingo
Interest in the hydraulic and mechanical characterization of shales has grown in recent years, because of their application in the context of energy geotechnics. In the frame of nuclear waste disposal shales are considered as host formations for the placem ...
E D P SCIENCES2020Hydro-mechanical response of Opalinus Clay shale: dependency on composition and burial depth
Shales are sedimentary formation currently studied for their involvement in many geo-energy related applications, such as radioactive waste disposal, CO2 sequestration, oil and gas extraction.
In Switzerland the Opalinus Clay shale has been selected has ho ...
EPFL2019Experimental Assessment of the Impact of Partial Saturation On the Mechanical Properties of Gas Shales
Lyesse Laloui, Alessio Ferrari, Alberto Minardi
The impact of partial water saturation on the mechanical behaviour of clays and claystones has been widely proved. This work aims at demonstrating that also for gas shales partial water saturation has a significant influ-ence on their stiffness and strengt ...
