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 ...
2023Nucleation, propagation, and scale dependence of laboratory frictional ruptures; implications for earthquake mechanics.
Earthquakes are natural phenomena that cause ground shaking and damage to people and infrastructures. Despite significant progress achieved in understanding how earthquakes start, propagate, and arrest, many aspects of their physics and mechanics remain no ...
EPFL2023On the scale dependence in the dynamics of frictional rupture: Constant fracture energy versus size-dependent breakdown work
Marie Estelle Solange Violay, Mathias Alexandre David Lebihain, François Xavier Thibault Passelègue, Fabian Barras, Federica Paglialunga
Potential energy stored during the inter-seismic period by tectonic loading around faults is released during earthquakes as radiated energy, frictional dissipation and fracture energy. The latter is of first importance since it is expected to control the n ...
2022Steadily Moving Semi-Infinite Hydraulic Fracture in a Poroelastic Media
Brice Tanguy Alphonse Lecampion, Andreas Möri
Linear elastic fracture mechanics has been widely used to describe the propagation of hydraulic fractures in rocks [1]. The embedding material is generally considered to be elastic and permeable, but the fluid exchange between the fracture and the media is ...
2022Spatio-temporal patterns of fluid-driven aseismic slip transients: implications to seismic swarms
Brice Tanguy Alphonse Lecampion, Alexis Alejandro Sáez Uribe
Seismic swarms are often interpreted to be driven by natural fluid pressurization in the Earth’s crust, when seismicity is observed to spread away from a common origin and follows approximately a square-root-of-time pattern of growth. On the other hand, a ...
EGU2022On the effects of fluid pressure variations on rock-mass and fault mechanical behaviour
In the past 20 years, the growing interest in deep geo-reservoirs for purposes such as carbon storage, waste water disposal, or geothermal energy exploitation have led to large-volume fluid injections into the upper continental crust. These fluid injection ...
EPFL2021Hydraulic fracture growth in quasi-brittle materials
Hydraulic fracturing is a technique often used in the oil and gas industry to enhance the production of wells in low-permeability reservoirs. It consists of fluid injection at a sufficiently large injection rate to create and propagate tensile fractures in ...
EPFL2021Heterogeneous Dynamic Fracture: Amplitude Scaling of Crack Front Deformations
Jean-François Molinari, Thibault Didier Roch, Mathias Alexandre David Lebihain
We study numerically the deformation of a dynamic crack propagating through a planar heterogeneous interface. We investigate the evolution of the front shape due to variations of fracture toughness, represented by weak and strong stripes parallel to the ru ...
2021Energy budget of laboratory earthquakes: a comparison between linear elastic fracture mechanics approach and experimental approach
Marie Estelle Solange Violay, François Xavier Thibault Passelègue, Federica Paglialunga
Earthquakes correspond to a sudden release of elastic energy stored during inter-seismic period by tectonic loading around fault. The earthquake energy budget consists of four non-independent terms: the energy release rate (by unit crack length), the fract ...
2020Propagation of fluid driven fractures in transversely isotropic material
The propagation of fluid driven fractures is used in a number of industrial applications (well stimulation of unconventional reservoirs, development of deep geothermal systems) but also occurs naturally (magmatic dyke intrusion). While the mechanics of hyd ...
