MARINE SEISMIC SURVEYING

摘要

In order to improve the repeatability of marine seismic surveys carried out over the same subsurface area using a towed seismic source and a towed array of seismic streamers, the source and streamer array used to perform surveys after the first are depth-controlled and steered laterally so that the sourc e and at least some of the sensors in the streamers occupy at least some of th e same positions as the source and sensors of the first survey.
