Abstract:
Method for obtaining zero offset or near zero offset data in a marine seismic streamer survey. An acoustic transmitter (41) is attached to one of the buoys (14 or 16) that provide flotation to each streamer (12) and tow umbilical (13). The acoustic transmitters, or single transmitter in the case of a 2-D survey, may be fired (71-73) before each shot from the survey air guns. The response to the acoustic transmitters recorded by the near sensors in each streamer, or by a water break sensor if provided, will be a near-zero to zero-offset record of the shallow subsurface below the water bottom.
