Title (EN) ACQUISITION SCHEME FOR VIBROSEIS MARINE SOURCES
(FR) DISPOSITIF D'ACQUISITION POUR SOURCES MARINES VIBROSISMIQUES
Abstract: front page image
(EN)Control mechanisms, computer software and methods for driving vibrational source arrays underwater. An incoherent acquisition scheme drives individual source elements simultaneously and incoherently while a coherent acquisition scheme drives high-frequency individual source elements simultaneously and incoherently and low-frequency individual source elements simultaneously and coherently. Thus, denser coverage and an increased energy input is achieved for the source arrays.
(FR)L'invention concerne des mécanismes de commande, un logiciel informatique et des procédés permettant de commander des réseaux de sources vibratoires sous l'eau. Un dispositif d'acquisition incohérente commande des sources distinctes simultanément et de manière incohérente pendant qu'un dispositif d'acquisition cohérente commande des sources distinctes haute fréquence simultanément et de manière incohérente et des sources distinctes basse fréquence simultanément et de manière cohérente. Ainsi, il est possible d'obtenir une couverture plus dense et un meilleur intrant énergétique pour les réseaux de sources.
