Reservoir characterization

This module is based on theoretical and practical teaching, with the aim of acquiring and implementing the various tools and methods of Geological - Geophysical - Reservoir integration at different scales (from Pore to Basin) essential for understanding the "Genesis and evolution of sedimentary reservoir systems" and necessary for pursuing careers in Georesources (hydrogeology, petroleum systems, geothermal energy, deep storage, geological imaging and modeling, etc.). ).
The genesis of geological reservoir systems is first addressed through theoretical considerations based on current sedimentary reservoir systems. These concepts are then put into practice by means of a field school organized as part of the "internship and field school" module, enabling students to expand on the theoretical concepts acquired during the course on current carbonate sedimentary systems, reservoir systems and diagenesis.
The stratigraphy and sedimentology of carbonate sedimentary systems is studied in the form of a project on rocks analogous to geological reservoirs. During this project, engineering students have the opportunity to make petrographic observations using various techniques: cathodoluminescence, staining, etc.
Diagenesis and the evolution of reservoir systems in general, and carbonate reservoirs in particular, will be taught through a combination of theoretical lectures and practical work in a micromacroscopy room to illustrate the concepts of: compaction, precipitation, dissolution, dolomitization, de-dolomitization, diagenetic environments, typology of pore systems in reservoirs, influence of diagenesis on reservoir quality, etc... Finally, the 10-day "internship and field school" is an opportunity to see first-hand the various aspects of diagenesis and the evolution of carbonate reservoir systems.
Finally, the geochemical aspects of carbonate reservoir systems are addressed through theoretical and practical aspects: isotope geochemical analytical methods, cathodoluminescence, fluorescence, EDS/EDAX, XRD, etc.
Skills to be acquired:

Define sedimentary and diagenetic environments based on the criteria of facies, sedimentary structures, biological elements, etc.
Establish a conceptual model of a platform and identify associated reservoir levels
Know how to use geochemical analytical methods (optical microscopy, SEM, etc.) to quantify reservoir formations
Understand gas-water-rock interaction within carbonate reservoir systems,Present work and results orally.

Basic knowledge of sedimentary systems, petrography, structural geology, mapping, petrophysical properties, etc.
