Multi-vessel coil shooting acquisition
View Patent ↗Methods for efficiently acquiring full-azimuth towed streamer survey data are described. The methods use multiple vessels to perform coil shooting.
1. A marine seismic acquisition system, comprising:
a first vessel having a seismic streamer array disposed thereon; and
one or more controllers programmed to cause the first vessel to travel along a first coil path during a multivessel coil shoot;
wherein the multivessel coil shoot comprises an acquisition configuration having a second vessel travelling along a second coil path.
2. The marine seismic acquisition system of claim 1 , wherein the first vessel includes a seismic source disposed thereon.
3. The marine seismic acquisition system of claim 1 , wherein the second vessel has a seismic source.
4. The marine seismic acquisition system of claim 1 , wherein the center of the first coil path is at an offset from the center of the second coil path.
5. The marine seismic acquisition system of claim 1 , wherein the first coil path and the second coil path are different.
6. The marine seismic acquisition system of claim 1 , wherein the first coil path and the second coil path are substantially the same.
7. The marine seismic acquisition system of claim 1 , wherein the second vessel travels ahead of the first vessel.
8. The marine seismic acquisition system of claim 1 , wherein the multivessel coil shoot collects full azimuth seismic data.
9. A marine seismic acquisition system, comprising:
a first vessel having a seismic source disposed thereon; and
one or more controllers programmed to cause the first vessel to travel along a first coil path during a multivessel coil shoot;
wherein the multivessel coil shoot comprises an acquisition configuration having a second vessel travelling along a second coil path.
10. The marine seismic acquisition system of claim 9 , wherein the first vessel comprises a seismic streamer array disposed thereon.
11. The marine seismic acquisition system of claim 9 , wherein the second vessel travels behind the first vessel.
12. The marine seismic acquisition system of claim 11 , wherein the second vessel comprises a seismic streamer disposed thereon.
13. The marine seismic acquisition system of claim 9 , wherein the first coil path and the second coil path are different.
14. The marine seismic acquisition system of claim 9 , wherein the center of the first coil path and the center of the second coil path are at an offset.
15. The marine seismic acquisition system of claim 9 , wherein the first coil path and the second coil path are substantially the same.
16. The marine seismic acquisition system of claim 9 , wherein the multivessel coil shoot collects full azimuth seismic data.
