The research unit Basins - Reservoirs - Resources (B2R) - UniLaSalle - UPJV - studies the evolution of sedimentary basins, reservoirs and sources of fossil and renewable energies (hydrocarbons, geothermal, water).

The scientific project

The B2R research unit's approach fits into a general context where energy demand is constantly growing due to the increase in world population and the emergence of many new countries. This growth in demand is accompanied, for industrialized countries, by an awareness of the strategic, environmental and societal issues raised by the need for natural resources: energy (oil, gas) or minerals.

On a global scale, it has become crucial to seek a diversification of energy sources. Sedimentary basins play a central role in this quest. They serve as reservoirs and sources for a range of energy resources, including renewable energies such as geothermal, hydrogen and hydropower. In addition, these basins are often used as storage sites for various forms of energy, as well as a CO2 capture and storage zone.

The studies

The B2R team studies the evolution of sedimentary basins, formed several million years ago, as it allows us to predict the evolution of current systems and their natural resource potential.

In these basins, the research unit is interested in the influence of physico-chemical parameters on the evolution of thermo-barometric markers such as: "crystallinity" of illite and chlorite, phyllosilicate reaction series, vitrinite reflectance, fission traces, fluid inclusions.

These physico-chemical parameters are indeed used to determine the pressure/temperature conditions of sedimentary basins to better characterize their evolution.

In the fields of diagenesis and anchimetamorphism, the research team focuses on :

  • question the reliability of the interpretations of the markers used for the thermo-barometric characterization of basins and the reservoirs they contain,   
  • to specify, by studying analogues and modelling, the characteristics of the evolution of these markers over time according to the geodynamic context considered, the lithologies encountered, and the circulation of fluids,   
  • to highlight the geological factors that influence these markers with emphasis on the control methods.

Within the general framework of the studies of sedimentary basin evolutionary processes, the scientific project of the B2R unit focuses on :

  • the integrated and critical analysis of thermo-barometric markers of this evolution,   
  • the correlation of the results from the interpretation of thermo-barometric markers with those from the interpretation of stratigraphic, diagenetic and structural markers,   
  • the highlighting of the modalities of control over time of the various factors on the properties of sedimentary reservoirs.

Research programs

(Multidisciplinary and multi-context demonstration of EGS exploration and Exploitation Techniques and potentials)

The objective of the project is to demonstrate the possibility of small-scale, low-cost production of electricity and heat in geologically diverse areas and to strongly increase the development of geothermal production sites in Europe in the near future, notably by capitalizing on the optimization of existing and non-operated oil wells.


Partners: B2R UniLaSalle - Ghislain TRULLENQUE and 13 other partners from 5 European countries.
