Evolution of water content and suction of Opalinus Clay from recovery at the drilling site to handling in the laboratory

Lyesse Laloui, Alessio Ferrari, Angelica Tuttolomondo

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 ...

Hydro-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 ...

Effect 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 ...

Experimental 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 ...

Developing 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 ...

Numerical 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 ...

Experimental 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 ...
