Ascent and movement of buoyant fluids in the lithosphere
Brice Tanguy Alphonse Lecampion, Andreas Möri, Carlo Peruzzo
Hydraulic fractures are driven by an internal fluid pressure exceeding the minimum compressive stress, propagating in a direction perpendicular to the latter. This class of tensile fractures has gained interest over the last fifty years due to the developm ...

Hydraulic fractures are driven by an internal fluid pressure exceeding the minimum compressive stress, propagating in a direction perpendicular to the latter. This class of tensile fractures has gained interest over the last fifty years due to the developm ...
EPFL2023Refineries in plains and valleys. Debating the environmental problems of oil infrastructure in Switzerland (1958-1966)
As oil consumption surged in Western Europe after 1945, its environmental and sanitary consequences became visible to consumers for whom they had remained largely hidden until then. Indeed, refineries had long been located in the producing countries or, in ...
2023A fully-coupled highly-parallelized geomechanical simulator for assessing induced seismicity
Jean-François Molinari, Brice Tanguy Alphonse Lecampion, Guillaume Anciaux, Nicolas Richart, Emil Gallyamov
Induced seismicity caused by anthropogenic modification of the subsurface effective stress state has been observed in a number of industrial applications -- from hydrocarbon extraction (e.g., Groningen [1]), drilling waste-water disposal (e.g., [2]) to the ...
2023Disentangling 1/f noise from confined ion dynamics
Ion transport through biological and solid-state nanochannels is known to be a highly noisy process. The power spectrum of current fluctuations is empirically known to scale like the inverse of frequency, following the long-standing yet poorly understood H ...
ROYAL SOC CHEMISTRY2023Expansion Work Recovery of Hydrogen for a FC-Truck-Tentative Design of an Expansion Machine
Hydrogen powered vehicles use high-pressure reservoirs from which the gas is transferred to the low-pressure fuel-cell via a classical pressure reduction valve. In these systems no expansion work is recovered and the question is addressed of the potential ...
MDPI2023Shearing and opening of a pre-existing discontinuity in response to fluid injection
Brice Tanguy Alphonse Lecampion, Ankit Gupta, Alexis Alejandro Sáez Uribe
We investigate the fluid-driven growth of a shear crack along a frictional discontinuity and its transition to hydraulic fracturing (sometimes referred to as hydraulic jacking) under plane-strain conditions. We focus on the case of a constant friction coef ...
2023Swelling and shrinkage of partially saturated gas shales: from laboratory tests to an effective stress framework
Gas shale swelling during hydraulic stimulation is one of the major challenges in unconventional gas development. It is hypothesized that the large volumetric strain upon water imbibition is a consequence of dramatic changes in capillary pressure and disjo ...
EPFL2022Hierarchical tensile structures with ultralow mechanical dissipation
Tobias Kippenberg, Alberto Beccari, Amirali Arabmoheghi, Nils Johan Engelsen, Sergey Fedorov
Structural hierarchy is found in myriad biological systems and has improved man-made structures ranging from the Eiffel tower to optical cavities. In mechanical resonators whose rigidity is provided by static tension, structural hierarchy can reduce the di ...
