What drilling engineering? This borehole has the particularity to have a double measuring chamber system: one in groundwater table at a depth of 12 meters and another in a geological layer (clay marls) at - 30 meters from the surface. What is measured with this drilling? Drilling will measure which gases are naturally present in the subsoil and aquifer, as well as their natural variations over time and seasons, outside any industrial activity. The goal is to create a geochemical baseline targeted at the soil gases: carbon dioxide CO2, methane CH4, oxygen O2 et nitrogen N2. What will the drilling be used for? The system will validate monitoring tools and protocols to control and measure the potential environmental impacts of a human activity on the subsoil and aquifer.

Previous Next Photographs: CNRS & GeoRessourcesThe laboratory team had the pleasure of welcoming Dominique Potier, Member of Parliament for the 5th district of Meurthe-et-Moselle on Wednesday, August 28, 2019. This meeting took place as part of the CNRS's 80th anniversary celebrations, an initiative to bring the worlds of research and politics closer together.After a presentation of the GeoRessources laboratory and the Regalor project by Jacques Pironon and Philippe de Donato, Dominique was able to discover the equipment of the platforms on the Artem sites and the Steval pilot plant.From the device used to control the behaviour of underground structures to the pilot plant for the valorisation of mining resources, as well as the storage of CO2 in the subsoil, Mr. Potier was able to appreciate the laboratory's extensive research work on the energy transition.
