Method and system of underwater acoustic positioning of seismic streamers based on modulated acoustic signals

摘要

Methods and systems for moving seismic streamer steering devices to target positionsare disclosed. One method comprises calculating forces required to steer oneor more seismic streamer steering devices in a seismic spread to target positions,the calculated forces based wholly or in part on information in modulated underwateracoustic transmissions, and steering the streamer steering devices to the targetpositions using the calculated forces.
