Fluid phases are involved in many geological processes and constitute important issues in terms of resources.
The team's objective is to understand the factors determining fluid transfers, taking into account the evolution at the geological timescale and the often complex architecture of the objects studied. While the approach is fundamental, the subject is conducive to the development of partnership projects. In addition, the team members are strongly involved in teaching, through the Master's courses in Hydrogeology and Reservoir Geology.
The team's expertise in the geology of carbonate systems is the basis of a research activity on the properties of carbonate rocks and massifs, considered as reservoirs or karsts, whether the fluid concerned is a hydrocarbon, water or CO2. On the other hand, we are developing new methods for the in situ study of fluid/mechanical couplings, and we use the results to re-examine the relationships between fluid migration, tectonic and seismic activity, and human activity.
The themes of water as a vital resource for humans and ecosystems represent major societal issues of local and international scope. CEREGE, through its methodological developments combining expertise in hydrology, advanced geochemical tools and numerical modelling, has the skills to play a major role and to have national and international visibility in the study of hydrosystems. The work carried out within the team aims to understand and/or quantify the transfer processes from the atmosphere to the subsoil, in aquifers, and then to surface aquatic environments. In this continuum, the measurement, understanding and modelling of fluxes and biogeochemical processes at interfaces is a priority for many programmes and/or organisations. On a regional scale, the work initiated will strengthen the integration of CEREGE and AMU in the region, through collaborations with regional actors (e.g. the Water Agency, river or aquifer syndicates, etc.). On an international scale, we place particular emphasis on the involvement of team members in projects in the South.
The research themes of the Resources, Reservoirs and Hydrosystems team are organised into 4 themes :
- Evolution of carbonate systems from the global to the reservoir scale
- Dynamics of sedimentary basins and fluid/mechanical coupling
- Water resources, energy resources and storage
- Tracing and quantifying flows at interfaces
