Title (EN) SYSTEM AND METHOD FOR ACQUISITION OF MARINE SEISMIC DATA
(FR) SYSTÈME ET PROCÉDÉ PERMETTANT L'ACQUISITION DE DONNÉES SISMIQUES MARINES
Abstract:
(EN) In a system and method for acquisition of marine seismic data, an array of N acoustic sources is suspended in a body of water from a float. At least N near-field sensor assemblies are configured between the array of N acoustic sources and the float. These N near-field sensor assemblies are each configured to concurrently measure both a pressure and a vertical pressure gradient of the acoustic wave in the water at any selected time.
(FR) Selon l'invention, dans un système et un procédé d'acquisition de données sismiques marines, un réseau de N sources acoustiques est suspendu à un flotteur dans un corps d'eau. Au moins N ensembles de capteurs de champ proche sont configurés entre le réseau de N sources acoustiques et le flotteur. Ces N ensembles de capteurs de champ proche sont chacun configurés pour mesurer simultanément à la fois une pression et un gradient de pression vertical de l'onde acoustique dans l'eau à n'importe quel moment sélectionné.
