The GEMex project is a cooperation in Geothermal energy research Europe-Mexico for development of Enhanced Geothermal Systems (Acoculco) and Superhot Geothermal Systems (Los Humeros). Los Humeros and Acoculco fields are located at the eastern edge of the Trans Mexican Volcanic Belt (TMVB), a region favourable for geothermal energy exploitation. In the framework of the European H2020 and Mexican CONACyT-SENER project GEMex, several geophysical, geological, and geochemical surveys have been carried out to better understand the structure and behavior of these geothermal reservoirs. In a broader context this acquired knowlegde, will become key for understanding regional geothermal resources for further development.
