Special issue: Earth sciences

Olga Vizika-KavvadiasPutting geological structures into equations and describing the processes involved in the formation of rocks, fluids and complex flows, in order to translate the rich diversity of natural media into numerical models: that's the ambition of the Geosciences Division.

Our researchers study geological objects covering spatial scales from the nanometer to hundreds of kilometers, and time scales from a hundredth of a second to a million years. Their aim is to remove the barriers inherent to the multiphysical/multiscale character of the phenomena that govern major natural systems: taking into account heterogeneities and uncertainties, changes in scale, and data acquisition to develop and validate models. 

This work has many applications, from petroleum exploration to enhanced oil recovery and fluid storage, all of which posing major economic and environmental challenges. The examples presented here illustrate the diversity of topics covered, the wide range of skills at work and the scientific quality of the research work carried out.

I hope you enjoy this issue of the newsletter,

Olga Vizika-Kavvadias, Director of the Geosciences Division
