GEOTREF will be represented at the World Geothermal Congress 2020 +1 (delayed by one year due to the health context). Exceptionally, the congress will initially take place via virtual sessions, during which the partners will be able to present their work through video recordings (Opening Event – 30/03/2021 ; Business & Environment – 13/04/2021 ; Geosciences – 11&12/05/2021 ; Engineering – 15/06/2021 ; Cutting Edge – 06/07/2021), then in a second step via a session with on-site presentations (On Site Conference – 24 to 27/10/2021).

GEOTREF in the headlines of the FA Guadeloupe newspaper, 2019 november 2nd

Le potentiel géothermique de la Guadeloupe a été sous-estimé

The geothermal power of Guadeloupe has been underestimated.

Scientific researches conducted in the last 5 years in the mark of the GEOTREF project are paying off. Guadeloupe geothermal potential seems to be very high and very promising.

Geothermal energy is endogenous and clean, much less expensive than electricity production based on oil or coal. Obvious Authority’s attraction towards it is enhanced by the actual context of energy transition. Besides, Elisabeth Borne, French minister for the ecological transition, and Frédérique Vidal, French minister for Research & Development, have visited the Bouillante power station on Sunday.
Electricity production based on geothermal energy has been raised up to 15 MW …

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.
