RESEARCH ACTIVITIES

After completing my engineering degree at Ecole des Mines, I wanted to perform research. The year that I spent in the Centre d'Informatique Géologique of Paris School of Mines, gave me the opportunity to learn about hydrogeology and put me in charge of developing an industrial version of BLUEPACK, the first geostatistical software specifically designed for the oil industry (initially developed for Shell).

This experience encouraged me to pursue a research career in geostatistics. I continued the inception and the development of BLUEPACK during a one year military duty that I spent at Geomath in Denver, a joint venture between the Ecole des Mines de Paris and the French Bureau de Recherches Géologiques et Minières (BRGM).

Then I returned to the Centre de Géostatistique in Fontainebleau where I have been actively involved in the development of both the algorithms and the computer code for successive versions of the Centre's geostatistical softwares. Let us mention in praticular:

  • MAGMA which was the first general purpose geostatistical software developed by the Centre.
  • ISATIS which has become the benchmark for scientific software in the geostatistical domain. In 1995 its commercialisation was transferred to Geovariances, a company that specialised in this field.
  • ISATOIL which was designed to calculate hydrocarbon volumes in places and was developed within the framework of a oil industry contract with Statoil.

All these specialized packages were finally regrouped into the first commercial package spacialized in Geostatisticscalled ISATIS. Initially conceived in the Centre de Geostatistics of the Ecole des Mines de Paris, it was entrusted to Geovariances company. My task is now to provide some help in terms of consultancy for the enhancement of this software, which is now upgraded into Isatis Neo platform.

Over the past 20 years I have also carried out many research contracts for companies and governmental agencies (Agip or ENI, Total, Statoil or Equinor, Charbonnages de France, Ifremer). I have been active in teaching, particularly short courses for industry, and in directing theses.

More recently, I initiated the development of the package RGeostats which is considered as the software development and testing plateform of the Geostatistical Team of the Center of Geosciences of Mines ParisTech.

In the last years, I have been involved in the development of SPDE (and its code within RGeostats) which stands as the new avenue for geostatistical applications.
