  • Leading Geoscience feasibility studies for the Moho Nord development project (Congo): the deep offshore development of two areas, Albian and Tertiary; studies conducted simultaneously by two geology-geophysics-deposit teams as part of an integrated feasibility group.
  • Coordinating redevelopment studies for mature fields in Gabon: compressing additional offshore gas, replacing obsolete living quarters, investigating a minimalist well platform, and studying low-cost pipes.

  • Providing technical monitoring for the entire Yamal LNG project on behalf of Total, one of the shareholders—covering not only the Construction phase, from drilling the wells to building the LNG plant and infrastructure, but also the Operations phase, including the commissioning and start-up of the facilities as well as the actual operations. As such, he takes part in the Yamal LNG technical committees.
