Quatrième de couverture : Shared earth modeling Knowledge driven solutions for building and managing subsurface 3D geological models Over the last two decades, earth modeling has become a major investigative tool for evaluating the potential of hydrocarbon reservoirs. Earth modeling must now face new challenges since petroleum exploration no longer consists in only investigating newly identified resources, but also in re-evaluating the potential of previously investigated reservoirs in the light of new prospecting data and of revised interpretations. Earth models incorporate a variety of different interpretations made on various types of data at successive steps of the modeling process. However, current modeling procedures provide no way to link a range of data and interpretations with a final earth model. For this reason, sharing and exchanging information about the model building process is at present a major difficulty. Recently, the term « Shared Earth Modeling » has been used for expressing the ides that earth models should be built in such a way that experts and end users can have access, at any time, to all the information incorporated into the model. This information does not only concern the data, but also the knowledge that geoscientists produce by interpreting these data. Accordingly, practical solutions must be studied for operating a knowledge-driven approach of Shared Earth Modeling. This is the goal of this book. This study of earth subsurface modeling is intended for several categories of readers. It concerns in the first place geologists, engineers and managers involved in the study and evaluation of subsurface reservoirs and hydrocarbon exploration. Relying on recent progress in various fields of computer sciences, the authors present innovative solutions for solving the critical issue of knowledge exchange at key steps of the modeling process. This book will also be of interest to researchers in computer science and, more generally, to engineers, researchers and students who wish to apply advanced knowledge-based techniques to complexe engineering problems.
Biographie de l'auteur : Michel Perrin is a retired Geology Professor from École des Mines de Paris - Paris Tech. After having acquired an extensive experience in various geological disciplines, he dedicated the last twenty years of his professional activity on the subject of geomodeling, collaborating with BRGM, IFP Energies nouvelles and various computer science research teams in France and other countries. His main concern has been developing practical solutions for putting geological knowledge at the center of the geomodeling process. Jean-François Rainaud is a Doctor in Geophysics. He is presently Senior Project Manager at IFP Energies Nouvelles. In the last fifteen years, he has been the leader of research projects supported by the European Community or by the French governmental authorities and has been at the origin of extensive commercial software for Hydrocarbon Reservoir Characterization. Jean-François Rainaud presently plays a major rote in the Energistics Special RESQML Interest Group (SIG).
