Congratulations to Dr. Marion Parquer who sucessfully defended his PhD on the 5th of April 2018! The video of the defense in now available (in French) on YouTube.

The RING teams wishes you an excellent holliday season, and a happy and peaceful year 2018 !


The animation shows possible grid geometries corresponding to stochastic correlations of the well data. For more detail, see Uncertainty management in stratigraphic well correlation and stratigraphic architectures: A training-based method.

In 1994, the Society of Petroleum Engineers gave Liliane Wietzerbin and Jean-Laurent Mallet the SPE Computer Application Best Paper Award for their article entitled Parameterization of Complex 3D Heterogeneities: A New CAD Approach. This paper proposed the Boolean simulation of channels and lobes represented as a smoothed backbone curve and associated cross-sections (this object is still known as GShape or Channel by Gocad users). That year, the average (inflation-adjusted) oil price was 26$ per barrel (source: 23 years later, the spot oil price is unfortunately much lower than most of us would like it to be, but it is still close to two times the 1994 amount! Both then and now, such descriptions of geological objects are highly relevant not only for thrill of advancing the science of quantitative geology, but also to optimize reservoir recovery. As a matter of fact, the paper by Wietzerbin and Mallet still reflects some essential characteristics of our research for integrative numerical geology: to improve the ability of numerical models to accurately forecast subsurface behavior, we need appropriate geometrical and petrophysical parameterizations of geological objects. Among the main evolutions since this seminal paper, we can mention the emergence of new ways to consider, explicitly or implicitly, the time dimension and the physics to integrate various types of subsurface data while considering uncertainties.

This meeting will, as each year, showcase some recent advances made by the RING team in addressing these difficult challenges.



A 7 minute movie presenting BIOMOre project has been released.
You'll find it here on the BIOMOre website.

BIOMOre is an European H2020 project for developing bio-in-situ-leaching of Copper ore.

This week, Yanis was with us at the RING team lab to discover numerical geology.

During his 3 day internship, he modeled the Solar System in 3D using Three.js
