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 positions are disclosed. One method comprises calculating forces required to steer one or more seismic streamer steering devices in a seismic spread to target positions, the calculated forces based wholly or in part on information in modulated underwater acoustic transmissions, and steering the streamer steering devices to the target positions using the calculated forces.
