Jean-Pierre Girard


Jean-Pierre Girard - Exploration Production - Total

Jean-Pierre Girard - Expert in Petrography, Diagenesis and Inorganic Geochemistry 

Jean-Pierre is a low temperature geochemist. After earning a PhD in applied geology & Clastic diagenesis from Université de Poitiers and a PhD in Sedimentary geochemistry and petrology from Université Aix-Marseille III, Jean-Pierre spent 7 years at Case Western Reserve University (USA) as a researcher.

Then, he worked for 13 years with the French Geological Survey (Bureau de Recherche Géologiques et Minières).

In 2007, he joined Total Exploration & Production as a specialist and Head of the Mineral Geochemistry Group at the Centre Scientifique et Technique Jean Féger in Pau, France. Today, he acts as a Reservoir geochemistry/diagenesis expert for Total Exploration & Production.

Jean-Pierre’s prime area of interest and research is in sandstone-carbonate diagenetic processes and their impact on reservoir quality. Currently, he is actively involved in projects dealing with:

  • Absolute Dating of diagenesis and fluid flow events in sedimentary basins
  • Reconstructing OVP history in deeply buried reservoirs
  • Analytical developments for the characterization of diagenetic processes at the micro-scale
  • Diagenesis of Presalt reservoirs
