(FR) PROCEDES ET APPAREIL POUR L'ACQUISITION DE DONNEES SISMIQUES MARINES
Abstract: front page image
(EN)Methods and apparatus for acquiring marine seismic data are described. One method comprises selecting tow depth of one or more marine seismic streamers based at least in part on lack of or presence of currents at different depths, and allowing the current to contribute to steering the streamers to desired lateral positions at the selected tow depth. One method comprises: (a) allowing a marine seismic streamer to be carried wi th a current at a first depth in a first lateral direction; and (b) raising or lowering the streamer to a second depth at which there is sufficient current in a second lateral direction substantially opposite to the first lateral direction to allow the current to force the streamer back toward a desired position during seismic data acquisition.
(FR)L'invention concerne des procédés et un appareil pour l'acquisition de données sismiques marines. Un procédé de l'invention consiste à sélectionner des profondeurs de remorquage d'une ou de plusieurs flûtes sismiques en fonction, au moins partiellement, de l'absence ou de la présence de courants à différentes profondeurs ; et à amener le courant à contribuer à orienter les flûtes à des positions latérales désirées à la profondeur de remorquage sélectionnée.
