Fluid thermodynamics control fault heating and weakening under upper crustal stress conditions

Marie Estelle Solange Violay, François Xavier Thibault Passelègue, Mateo Alejandro Acosta

Although fluids are pervasive among tectonic faults, thermo-hydro-mechanical couplings during earthquake slip remain unclear. In particular, fluid induced seismicity is today a subject of major interest for the geo-energy community. We report full dynamic ...

Viscosity fluid influence on stick-slip motions

Marie Estelle Solange Violay, Chiara Cornelio

The Enhanced Geothermal System (EGS) offers a great potential for developing the use of geothermal energy, allowing the creation of hydrothermal reservoirs in deep and hot geological formations, where energy production was impossible due to a lack of fluid ...

Fluid injection in a frictional weakening fracture

Brice Tanguy Alphonse Lecampion, Federico Ciardo

Understanding the mechanism of nucleation of dynamic rupture is an important issue in seismology since it is the key factor in determining the seismic potential of pre-existing faults under long-term loadings. Furthermore, the activation of Mode II crack b ...

Integration of deep geothermal energy and woody biomass conversion pathways in urban systems

François Maréchal, Stefano Moret, Léda Gerber, Emanuela Peduzzi

Urban systems account for about two-thirds of global primary energy consumption and energy-related greenhouse gas emissions, with a projected increasing trend. Deep geothermal energy and woody biomass can be used for the production of heat, electricity and ...

Modelling of fluid injection into a frictional weakening dilatant fault

Brice Tanguy Alphonse Lecampion, Federico Ciardo

Understanding the mechanism of nucleation of dynamic rupture is an important issue in seismology. It is the key factor in determining the seismic potential of pre-existing faults under long-term loadings. Furthermore, the activation of Mode II fracture by ...

Simulating fully three-dimensional pressurized fracture propagation

Brice Tanguy Alphonse Lecampion, Dmitry Nikolskiy

We report the progress on a new computational technique for fully three-dimensional simulation of propagation of hydraulic fractures in the vicinity of a wellbore. One of the components of this technique is the boundary element code for modeling the elasti ...

Underground Potential for Urban Sustainability: Mapping Resources and Their Interactions with the Deep City Method

Philippe Thalmann, Aurèle Parriaux, Michael Robert Doyle

In the process of urban growth, the underground is often only addressed once all surface alternatives have been exhausted. Experience shows that this can lead to unforeseen conflicts (e.g., subsidence, groundwater pollution) and to lost opportunities (e.g. ...

Laminar - turbulent transition in the propagation of height contained hydraulic fracture

Brice Tanguy Alphonse Lecampion, Haseeb Zia

High injection rate hydraulic fracturing can have Reynolds number as high as 10000. For such high Reynolds numbers, turbulent flow is likely to occur. In this paper, we investigate the effect of turbulence on the propagation of hight contained hydraulic fr ...

Geothermal Energy and Biomass Integration in Urban Systems: a Case Study

François Maréchal, Stefano Moret, Léda Gerber, Emanuela Peduzzi, Frédéric Louis-Pierre Raphaël Marie Amblard

Heating, electricity and transportation are the three components of urban systems final energy consumption. Geothermal energy and biomass are two promising renewable energy resources that can be used for the production of heat, electricity and biofuels, th ...
