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: https://inflationdata.com). 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.
