Project 636 - Characterization and sustainable exploitation of geothermal resources

Brief outline of the project

Geothermal fluids are extracted through deep wells drilled in a geological reservoir, which can be represented by highly heterogeneous volcanic complex, sedimentary basins or deep basement rocks. If the reservoir is not enough permeable for a profitable exploitation of geothermal fluids, it is enhanced through different engineered techniques in order to improve its exploitation.

The main objective of this project is to propose suitable methodologies and techniques for the characterization and modeling of fractured geothermal reservoirs, to ensure their sustainable exploitation and, therefore, ensure acceptation of this kind of energy by local communities.

This goal will be achieved with experiences from the volcanic complex of the Nevado del Ruiz (Colombia), the St. Lawrence Lowlands sedimentary basins (Québec, Canada), the Carboniferous limestone reservoir in the area of Mons (Belgium), the Soultz site and the Ploemeur fractured rock experimental site (France). Further, a site in Chile will also be considered. Ongoing and planned work conducted at these sites from international researchers teaming together will provide field data for modeling purposes of highly heterogeneous geological structures. This work will provide new insights into the construction of conceptual and numerical models for geothermal reservoirs, using available information from sites in Europe, North and South America.
