Title
(EN) DETERMINING THE STRUCTURE OF A TOWED SEISMIC SPREAD ELEMENT
(FR) DÉTERMINATION DE LA STRUCTURE D'UN ÉLÉMENT DE PROPAGATION SISMIQUE REMORQUÉ
Abstract
(EN)
A technique includes obtaining a plurality of sets of measurements of distances between nodes located on a seismic spread element while the element is in tow. Each set is acquired in response to the operation of a different set of sources. The technique includes determining a three-dimensional structure of the seismic spread element while in tow based at least in part on the sets of measurements.
(FR)
La présente invention concerne une technique qui comprend l'obtention d'une pluralité de jeux de mesures de distances entre des nœuds situés sur un élément de propagation sismique pendant que l'élément est remorqué. Chaque jeu est obtenu en réponse au fonctionnement d'un jeu différent de sources. La technique comprend la détermination d'une structure tridimensionnelle de l'élément de propagation sismique pendant le remorquage sur la base au moins en partie des jeux de mesures.
