GEMex

GeMex is a Horizon 2020 project in which a European and a Mexican consortium joined forces to study two geothermal sites in Mexico: one for the development of an Enhanced Geothermal System (EGS) and the other a high-temperature system (SHG).

The objectives are: 1) the resource assessment at two unconventional EGS and superhot (SHG) geothermal Mexican sites by understanding the geological context and the edifice of geothermal systems; 2) reservoir characterization with conventional and novel geophysical and geological methods by using gravity, magnetics, GPS and InSAR data for joint inversion with seismic active and passive data; 3) concepts for Site Development by using all existing and newly collected information to define drill paths, to recommend a design for well, and to investigate optimum stimulation and operation procedures.

OGS contributed with reprocessing and interpretation of legacy active seismic data, tomographic inversion of newly acquired passive seismic data and numerical seismic wavefield simulations including rock and seismic parameters dependence on temperature and geothermal fluids.
