The aim of this course is to harmonize the knowledge of students from different backgrounds. The course focuses in particular on mineralogy, magmatic petrology and associated metal deposits. These disciplines are approached with a synthetic and global approach, integrating processes and linking the main mineralogical and geochemical reservoirs. The course is supported by practical work in magmatic petrology and metallogeny, involving the study of macroscopic and microscopic rock and mineral samples.

The content of the module is divided into 3 sequences:

1) a sequence to define concepts, get to grips with a tool (R) and review the vocabulary of statistical estimation and its application to the calibration of hydrological parameters;

2) a sequence on uncertainty and sensitivity analysis methods, and

3) a sequence on data assimilation applied to hydraulic modeling. The course will also be introduced by a presentation from a design office executive on the usefulness of this type of approach in engineering.

The emphasis will be on alteration processes and fluid/rock interactions, but above all on structural and textural constraints to propose constrained, innovative and original deposit models. In this course, we will insist on the structural specificity of each deposit and on the dangers of the sometimes blind application of book models.

Definition, typology and in-depth analysis of naturally fractured reservoirs (NRF) in different geological contexts: different rock types (carbonates, clays, basement), burial, diagenesis, exhumation, folding, fault damage, cooling, mineralogical change. Anthropogenic induced fracturing systems (hydraulic, thermal), applications to clay reservoirs (shale plays), cap clays and storage sites.
Integration of this knowledge into the exploration and exploitation of fractured reservoirs.
Concept and workflow for editing DFNs (discrete fracture networks).
Free 2-day talk by Bertrand Gauthier from Total: Static and dynamic properties of fractured petroleum reservoirs.
