Patent number: 9214041Abstract: The invention pertains to a method for enhancing the determination, from a seismic image of at least a portion of a seismic horizon in a three-dimensional domain. The method comprises: receiving the seismic image; receiving a plurality of related control points; defining pseudo-rectangles; for each pseudo-rectangle applying a diffeomorphic transformation F: defining a new domain; transforming points of the seismic image; transforming said pseudo-rectangle into a corresponding rectangle; applying a horizon reconstruction algorithm to the transformed points, to determine a part of a transformed horizon, the reconstruction comprising solving a Poisson equation; and computing a part of the horizon, said computing comprising applying an inverse diffeomorphic transformation F?1 to the determined part of a transformed horizon.Type: GrantFiled: August 6, 2013Date of Patent: December 15, 2015Assignees: Total SA, Centre National de la Recherche Scientifique—CNRS, Universite de Bordeaux, Ecole Nationale Supérieure des Sciences Agronomique de Bordeaux-Aquitaine, Institute Polytechnique de BordeauxInventors: Guillaume Zinck, Marc Donias, Jacques Daniel, Olivier Lavialle, Sébastien Guillon

Patent number: 8811677Abstract: The invention targets in particular a method for searching for a seismic horizon in a seismic image of the subsoil. The method notably comprises the designation of two points belonging to the horizon sought, the iterative search for the best solution for the equation of the seismic horizon notably by virtue of a breakdown of this solution into two components, a pseudo-continuous component and a jump component.Type: GrantFiled: September 6, 2012Date of Patent: August 19, 2014Assignee: Total SAInventors: Sebastien Guillon, Guillaume Zinck, Marc Donias, Olivier Lavialle

Publication number: 20060269139Abstract: The invention provides a method for finding discontinuities in an image. This method makes it possible to detect discontinuities, i.e. faults, by being based on the heterogeneity of the distribution of the gradients of the points of the image being studied. The heterogeneity of the distribution of the gradients is characteristic of the discontinuities in a stratified medium. The method is based on the characteristics of the discontinuities within the set of geological markers in order to obtain a better determination of these discontinuities.Type: ApplicationFiled: March 28, 2006Publication date: November 30, 2006Applicant: TOTAL S.A.Inventors: Naamen Keskes, Sebastien Guillon, Yannick Berthoumieu, Marc Donias

Patent number: 6771800Abstract: The method uses the image obtained by accumulating continuity curves representative of seismic horizons so as to determine the geological strata constituting the seismic section, such as they were deposited and not such as they are observed today. To do this, the method defines a transformation of the vertical scale of the seismic section, scale measured in seismic times, into a geological vertical scale measured in geological times. This transformation is based on an equalization of histograms. Starting from equalized histograms, the method makes it possible to determine equalized seismic sections which are used to determine the rates of sedimentation which governed the depositions of geological strata. In particular, it highlights geological hiatuses, that is to say erosions and gaps.Type: GrantFiled: April 25, 2001Date of Patent: August 3, 2004Assignee: ELF Exploration ProductionInventors: Naamen Keskes, Sébastien Guillon, Marc Donias, Pierre Baylou, Fabien Pauget
