Description de la mission

As France's national geological survey, the BRGM (Bureau de recherches géologiques et minières) is the country's leading public body when it comes to earth science, responsible for managing resources and risks relating to the earth and the subsurface (www.brgm.eu). The work carried out by the BRGM is geared towards scientific research, supporting public policies and international cooperation.

This thesis project aims to evaluate the performance and safety of geological storage of Hydrogen in deep saline aquifer using CO2 as cushion gas through a advanced open-source simulator code - COMPASS. The work will focus in the good description of the storage concept, then its integration in the simulator and application for conceptual and realistic reservoir models.

Contexte

Hydrogen storage is currently operated in salt caverns; however, salt caverns are relatively small and have a limited distribution worldwide. Deep saline aquifer offers medium to very large storage capacity and are spread worldwide. The geological storage in deep porous media (saline aquifers) is well known by the industry with regard to the storage of CH4 and the town gas, whereas the storage of hydrogen is still a challenge as operating projects do not exist.

An optimal performance for hydrogen storage in deep saline aquifers is a function of the reservoir/seal system in trapping the fluids and having enough working gas capacity to withdraw hydrogen as pure as possible according to the demand. Performance studies imply the calculation of complex equations of fluid mechanics and phase equilibria for the formation water (brine), for the stored gas and for their interaction between them and within the reservoir. To solve these complex calculations, the utilization of 3D modelling and numerical simulations is required.

Profil

The candidate has a Master's degree (or equivalent) in geosciences, geophysics, engineering, mechanics, computer science or equivalent with a strong focus on fluid mechanics and/or reservoir simulation. Although the candidate will not be in charge of the development of mathematical models, an affinity with modelling is expected. The work on the simulation tool involves programing mainly in Python. Some developments in C++ or Fortran could be necessary to improve the routine.

-Knowledge on fluid mechanics and/or reservoir simulation;
-affinity with mathematical modelling is expected;
-Connaissance et maitrise d'outils avancés de programmation (Python, C++, Fortran) ;
-excellent communication skills;
-proficiency in spoken and written English;
-French is a plus;
