The “Reservoirs and Resources” work line is focused on analyzing the potential of critical raw materials present in fluid-hosted reservoirs, as well as studying the dynamic and transient behavior of these geological systems under extraction and reinjection processes. This work line includes the geological, hydrogeological, geochemical, and structural characterization of salt flats, geothermal reservoirs, and other brine-rich systems in order to understand the processes controlling the distribution, concentration, and mobility of elements of interest such as lithium, potassium, manganese, and strontium.
In addition, it incorporates numerical modeling tools to evaluate solute transport, water-rock interactions, and the long-term effects associated with resource exploitation, including clogging risks, hydrochemical changes, and reservoir sustainability. The objective is to generate robust scientific foundations that support the development of extraction strategies compatible with the conservation and stability of natural systems.
