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 ...

Additive and digital manufacturing of transient sensors and bioelectronics

Nicolas Francis Fumeaux

Transient electronics have emerged as a promising class of devices, capable of breaking down without harmful side effects to their environment. They have tremendous potential as bioresorbable electronics for temporary applications in the human body, and as ...

Insights 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 ...

Hinges for origami-inspired structures by multimaterial additive manufacturing

Jamie Paik, Jian-Lin Huang, Ralph Spolenak

Recent studies demonstrate novel metamaterials featuring unique properties by combining origami-inspired designs with additive manufacturing. In particular, the use of flexural hinges endow distinct advantages toward miniaturization and fabrication; howeve ...

Mechanical and hydraulic transport properties of transverse-isotropic Gneiss deformed under deep reservoir stress and pressure conditions

Marie Estelle Solange Violay, Mateo Alejandro Acosta

In central Europe, many geo-energy reservoirs have revealed to be hosted in transverse isotropic crystalline rock, where the rock's mechanical and hydraulic transport properties are poorly constrained. Here, we performed triaxial experiments on Cresciano G ...

Pore space properties in carbonate fault rocks of peninsular Italy

Marie Estelle Solange Violay

The fault cores of extensional faults in Mesozoic limestones and dolostones are examined by mean of combined microstructural, ultrasonic and petrophysical analyses. Grain-supported fault rocks commonly localize in the outer fault cores, whereas matrix-supp ...

Sensitivity of Simulated Steel Column Instabilities to Plasticity Model Assumptions

Dimitrios Lignos, Albano António De Abreu E Presa De Castro E Sousa, Alexander Riley Hartloper

Current experimental studies on the seismic behavior of steel wide-flange columns under multi-axis cyclic loading reveal that these members, depending on their geometric characteristics, may be susceptible to axial shortening, out-of-plane deformations and ...

STIMDESIGN: Hydraulic stimulation design for deep geothermal reservoirs - a numerical approach

Brice Tanguy Alphonse Lecampion, Federico Ciardo

This report is the third intermediate report of the StimDesign project which will finish in June next year. The focus is here solely on our two dimensional numerical developments. We report advances on the different building blocks of our numerical model: ...

Reservoir stimulation’s effect on depletion-induced seismicity

Lyesse Laloui, Barnaby Padraig Fryer, Gunter Siddiqi

Depletion-induced seismicity can pose a problem in some fluid-producing subsurface reservoirs, in some cases requiring production rate control in order to limit the seismicity. This study investigates the use of reservoir stimulation to reduce the depletio ...

Effect of dilatancy on a frictional weakening fault subjected to fluid injection

Brice Tanguy Alphonse Lecampion, Federico Ciardo

Fluid injection at a pressure below the local minimum principal total stress in a fault may (re)activate shear crack propagation (hydroshearing). Because of the presence of asperities along the fault's surfaces, fault hydraulic width increase with slip. Sc ...
