On the Fluid Retention Properties of Shales

Lyesse Laloui, Alessio Ferrari, Valentina Favero

The development of engineering activities involving shales such as the extraction of shale gas and shale oil, the nuclear waste geological storage and the sequestration of CO2, has led to an increasing interest toward the geomechanical behaviour of this ge ...

Retention Properties and Permeability of Shales

Valentina Favero

The water retention mechanisms play a major role in either fluid trapping due to the capillary forces present in low permeability formations, as in the case of shale gas reservoir, or in the resaturation of shale formations after ventilation, as in the cas ...

An Insight into the Fluid Retention Capabilities of Shales

Lyesse Laloui, Alessio Ferrari, Valentina Favero

The hydro-mechanical behaviour of shales is becoming one of the most important issues in modern geomechanics, largely driven by petroleum industries (i.e., the extraction of shale gas), the sequestration of CO2 and the nuclear waste geological storage. In ...

Volumetric behavior and consolidation of shales at high confining stresses

Lyesse Laloui, Alessio Ferrari, Valentina Favero, Donatella Manca

The analysis of the volumetric behavior and the consolidation of shales require the involved materials to be tested under high confining stresses. The paper presents the apparatuses and the techniques that have been developed recently for testing shales un ...

Hydrophobic Meshes for Oil Spill Recovery Devices

Francesco Stellacci

Widespread use of petrochemicals often leads to accidental releases in aquatic environments, occasionally with disastrous results. We have developed a hydrophobic and oleophilic mesh that separates oil from water continuously in situ via capillary action, ...

ACMEG-T: Soil Thermo-Plasticity Model

Lyesse Laloui, Bertrand François

This paper addresses an advanced and unified thermo-mechanical constitutive model for cohesive soils. Based on experimental evidence showing the non-linear and irreversible thermo-mechanical responses of saturated soils, the constitutive equations of the d ...
