Abstract
The invention relates to a seismic acquisition process where the streamers are intentionally directed to follow an oscillating sweep pattern behind a tow vessel to counteract the effect of the large gaps between the streamers while acquire a wide sweep of data through each pass over the survey area.
Claims14
A process for acquiring seismic data in a marine environment using seismic receivers mounted to streamers in the water following behind a tow vessel, the process comprising:
- a) installing a series of guidance devices along the length of each streamer, each guidance device having with a steerable element;
- b) directing the tow vessel to follow a path through the water where the path that the tow vessel has taken is a non-oscillating navigated path through a survey area;
- and
- c) steering each of the guidance devices to cause the streamers to undertake an oscillating path of back and forth sweeps across the navigated path.
