Towards an open geotechnical data platform in France
Isabelle Halfon, Mickaël Beaufils
An important quantity of geotechnical data is constantly collected for all the new projects of civil engineering. This data includes generally core and destructive boreholes, in wh…
Evidence of localized groundwater flow during thermal response test using distributed thermal sensing
Antoine Voirand, Charles Maragna
Four Borehole Heat Exchangers (BHE) were installed at the BRGM Shallow Geothermal Research Facility (BRGM-SGRF) in Orl{é}ans, France. They are sixty meters deep and eight meters ap…
Planetesimal gravitational collapse in a gaseous environment: Thermal and dynamic evolution
P. Segretain, H. Méheut, M. Moreira +3
Planetesimal formation models often invoke the gravitational collapse of pebble clouds to overcome various barriers to grain growth and propose processes to concentrate particles s…
Multimethod geophysical modelling for granite-related tungsten exploration: example of the Puy-les-Vignes/ Saint-Goussaud district (Limousin, France)
Geoffrey Dubreuil, Matthieu Harlaux, Guillaume Martelet +6
In the last decade, EU became aware of its dependency on mining countries for mineral resources. In that context in 2022, France launched new airborne geophysical surveys in the Li…
Ground electrical and electromagnetic methods for deep mineral exploration -- results from the SEEMS DEEP project
Mathieu Darnet, Bitnarae Kim, Simon Vedrine +10
The transition towards carbon neutral transportation and energy sources increases the global demand for mineral raw materials while easy-to-find near-surface (\< 200 m) ore deposit…
Towards a multi-physics multi-scale approach of deep geothermal exploration
M. Darnet, S. Vedrine, F. Bretaudeau +10
A wide range of geophysical methods is used for the exploration of deep geothermal resources. It aimsat characterizing the deep fractured network and its capacity for fluid/heat ex…
Block-Additive Gaussian Processes under Monotonicity Constraints
M. Deronzier, A. F. López-Lopera, F. Bachoc +2
We generalize the additive constrained Gaussian process framework to handle interactions between input variables while enforcing monotonicity constraints everywhere on the input sp…
Exploration of the deep geothermal potential of Petite-Terre Island in Mayotte
Chrystel Dezayes
In 2017, the electricity mix of the Department of Mayotte included 5% photovoltaic production, spread over more than 70 installations on the island, and 95% diesel thermal producti…
Petrophysical Characterization of Fractured Limestone from Beauce Aquifer Vadose Zone (O-ZNS Observatory, France)
Abdoul Nasser Yacouba, C. Mallet, J. Deparis +4
In recent years, water needs increased, driven by climate change and world population growth. In this context, we study groundwater flow in the vadose zone of Beauce aquifer (O-ZNS…
On the use of time series to improve signal processing of electrical data
Deparis Jacques, Gance Julien, Orlando Leite
Electrical Resistivity Tomography (ERT) has become widely used for engineering and environmental applications in the last couple of decades due to (1) the simplification and automa…
Empirical quantification of rockfall reach probability: objective determination of appropriate topographic descriptor
Marc Peruzzetto, Bastien Colas, Clara Lévy +2
For rockfall hazard assessment on areas more than several km2 in size, the quantification of runout probability is usually done empirically. Classical methods use statistical distr…
