Title (EN) PROCESSING SEISMIC DATA
(FR) TRAITEMENT DE DONNÉES SISMIQUES
Abstract:
(EN) Embodiments of the invention provide a method of processing marine seismic data, the data having been acquired using a "dense over/sparse under" streamer array having N over streamers disposed at a first depth and M under streamers disposed at a second depth greater than the first depth, where 0 < M < N. The method comprises: a) processing seismic data for one of the over streamer target locations and seismic data for one of the under streamer target locations; b) processing seismic data for another of the over streamer target locations; and c) combining the result of (a) and the result of (b). The one of the over streamer target locations and the one of the under streamer target locations may lie in a vertical plane.
(FR) L'invention concerne, selon des modes de réalisation, un procédé de traitement de données sismiques marines, dans lequel les données sont obtenues en utilisant un réseau de flûtes « dense dessus/clairsemé dessous » comprenant N flûtes supérieures disposées au niveau d'une première profondeur et N flûtes inférieures disposées au niveau d'une seconde profondeur supérieure à la première, où 0 < M < N. Le procédé comprend : a) le traitement de données sismiques pour l'un des emplacements cibles de flûte supérieure et de données sismiques pour l'un des emplacements cibles de flûte inférieure, b) le traitement des données sismiques pour un autre des emplacements cibles de flûte supérieure; et c) l'association du résultat de a) et du résultat de b). L'un des emplacements cibles de flûte supérieure et l'un des emplacements cibles de flûte inférieure peuvent se situer dans un plan vertical.
