2019 October 30 9th GEOTREF PhD defense

The ninth GEOTREF PhD has been defended by Alexiane Favier, the 30th October 2019, in the Université des Antilles, pôle Guadeloupe In Pointe-à-Pitre: Evolution of hydrothermal fluids in the upper crust of the Lesser Antilles island arc in Guadeloupe: applications to the geothermal systems.


This thesis, as part of the GEOTREF project (a multidisciplinary innovative platform for exploration and development of high-enthalpy GEOThermal energy in Fractured REservoirs), aims to improve the thermo-mechanical evolution of high-energy geothermal reservoirs. The geothermal potential of Lesser Antilles arc is known since the 1980s in the geothermal field of Bouillante in Guadeloupe. In order to develop this resource, it is necessary to identify possible new key targets, and to better understand the modes of fluids and heat transfers in high-enthalpy geothermal reservoirs.

2019 September 25 8th GEOTREF PhD defense


The eight GEOTREF PhD has been defended by Margaux Raguenel, the 25th September 2019, in the Ecole Nationale Supérieure de Géologie (ENSG) In Nancy: Modeling the thermo-hydrolic behavior in fractured reservoirs with unstructured meshes: application to the geothermal Reservoir of Basse-Terre, Guadeloupe.


The quantification of natural geological resources (oil, gas, water, ore depo-sits, geothermal energy, etc) calls for a precise understanding and description of the geological heterogeneities and physical and chemical processes that influence their formation, their settings, their preservation and their recovery.

2019 June 27 7th GEOTREF PhD defense

The seventh GEOTREF PhD has been defended by Dac Thuong NGO at 2 pm, the 27th June 2019, in the Ecole des Mines de Paris: Numerical modeling of hydraulic stimulation and induced seismicity in deep geothermal reservoirs.


Geothermal energy is a renewable resource that can provide base-load energy for electricity production or heating purposes without, or with limited, emission of green house gases. However, the development and the exploitation of deep geothermal power plants is usually accompanied by induced seismicity – a side effect that can raise serious concerns to the public and may prevent large-scale application of geothermal energy.

2018 October 31 3rd GEOTREF PhD defense

The third GEOTREF PhD has been defended by Viven Navelot at 2 pm, the 31st October 2018, in the Ecole Nationale Supérieure de Géologie de Nancy: Structural and petrophysical characterization of a geothermal system in a volcanic subduction arc context. Example of the Guadeloupe archipelago.


Geothermal systems located on active volcanic islands lying above subduction areas are increasingly being prospected and exploited as they represent significant, renewable and accessible energy resources with relatively low operating costs. The Basse-Terre Island in the Guadeloupe archipelago and more precisely the Vieux-Habitants area gathers several indicators allowing to suppose the occurrence of a high-temperature hydrothermal system.

2018 September 28 2nd GEOTREF PhD defense

The second GEOTREF PhD has been defended by Keurfon Luu on septembre 2018 at 2 pm, the 28th September, in the Ecole des Mines de Paris : Numerical optimization using stochastic evolutionary algorithms: application to seismic tomography inverse problems.


Seismic traveltime tomography is an ill-posed optimization problem due to the non-linear relationship between traveltime and velocity model. Besides, the solution is not unique as many models are able to explain the observed data. The non-linearity and non-uniqueness issues are typically addressed by using methods relying on Monte Carlo Markov Chain that thoroughly sample the model parameter space. However, these approaches cannot fully handle the computer resources provided by modern supercomputers.
