Georessources & Environment

Focuses of research & scientific skills

Sedimentary systems and carbonate reservoirs

To understand the structural and diagenetic sedimentary processes at the origin of the heterogeneity of carbonate systems and reservoirs at different scales by associating the study of the architecture of sedimentary bodies, their temporal evolutions and the different mechanisms of transfer (hydrous, hydrodynamic , thermal, gas, ...)

• Factors controlling the architecture and dynamics of sedimentary systems
• Genesis and diagenesis of carbonate and siliciclastic reservoirs

Hydrogeology and environment

To understand the modalities of pressure, mass and energy transfer within complex aquifers (free or captive) subjected to natural / anthropic pressures by a multidisciplinary integrating approach (hydrodynamics, geochemistry, isotopy ...).

• Transfer and recharge dynamics, interactions & exchanges within complex aquifers
• Transfer of pollutants, decontamination of contaminated sites and soils, geoelectrical methods.
• Imaging - Remote sensing
