Title (EN) METHOD FOR SEISMIC DATA ACQUISITION AND PROCESSING
(FR) PROCÉDÉ D’ACQUISITION ET DE TRAITEMENT DE DONNÉES SISMIQUES
Abstract:
(EN) Methods are described for separating the unknown contributions of two or more sources from a commonly acquired set of wavefield signals representing a wavefield where the sources are laterally located relatively close to each other and fire relatively close in time and where the contributions from different sources are separated using different source encoding techniques in different parts of the frequency band of interest.
(FR) La présente invention concerne des procédés pour séparer les contributions inconnues de deux ou plus de deux sources d’un ensemble de signaux de champ d’ondes communément acquis représentant un champ d’ondes où les sources sont latéralement situées relativement proches les unes des autres et déclenchées relativement près dans le temps et où les contributions des différentes sources sont séparées au moyen de différentes techniques de codage de source dans différentes parties de la bande de fréquences d’intérêt.
