Seismic streamer platform
View Patent ↗A technique includes designing a streamer, which includes a cable and seismic sensors based at least in part on a relationship between vibration noise and a bending stiffness of the cable.
1. An apparatus comprising:
a streamer having multi-component seismic sensors and having a bending stiffness greater than fifty Nm 2 to cause a vibration noise to not be significantly aliased into signals acquired by the sensors.
2. The apparatus of claim 1 , wherein the streamer cable has a diameter of substantially fifty millimeters and the determined bending stiffness is in a range from fifty Nm 2 to five hundred Nm 2 .
3. The apparatus of claim 2 , wherein the streamer cable has a diameter of substantially sixty millimeters and the determined bending stiffness is in a range from one hundred Nm 2 to one thousand Nm 2 .
4. The apparatus of claim 1 , wherein the multi-component seismic sensors comprise particle motion and pressure sensors.
5. The apparatus of claim 1 , further comprising a processor to process data acquired by the sensors.
6. The apparatus of claim 5 , wherein the processor is attached to the streamer.
7. The apparatus of claim 1 , further comprising:
a survey vessel to tow the streamer.
8. The apparatus of claim 7 , further comprising:
a processor located on board the survey vessel, the processor adapted to process data acquired by the sensors.
9. An apparatus comprising:
a streamer having multi-component seismic sensors and a cable,
wherein the cable has a bending stiffness greater than fifty Nm 2 and the sensors having a spacing greater than fifty centimeters.
10. The apparatus of claim 9 , wherein the cable has a diameter of substantially fifty millimeters, and the bending stiffness is in a range from fifty Nm 2 to five hundred Nm 2 .
11. The apparatus of claim 9 , wherein the cable has a diameter of substantially sixty millimeters, and the bending stiffness is in a range from one hundred Nm 2 to one thousand Nm 2 .
12. The apparatus of claim 9 , wherein the multi-component seismic sensors comprise particle motion and pressure sensors.
13. The apparatus of claim 9 , further comprising a processor to process data acquired by the sensors.
14. The apparatus of claim 13 , wherein the processor is attached to the streamer.
15. The apparatus of claim 9 , further comprising:
a survey vessel to tow the streamer.
16. The apparatus of claim 15 , further comprising:
a processor located on board the survey vessel, the processor adapted to process data acquired by the sensors.
