Mathematics) during 6 weeks. The goal of this event is to bring together scientists from both the

academic and industrial communities and work on some topics through several lectures and

research projects.

Sonia Benteboula and Alexandra Claisse co-supervised with Abdallah Benali and Pascal Have on the

research project «Co-refinement of fault surfaces».

PROFESSIONAL REPORTS

Integrated basin modeling provides a strategy for optimizing oil exploration in frontier areas and evaluating

new plays within well-explored basins. In these reports, we describe the methodology of 3D basin modeling

developed in the simulator TEMIS 3D. The simulator TEMIS 3D span the entire process of source rock burial,

hydrocarbon generation, expulsion, migration into a potential trap, and assessment of trap integrity
