Abstract

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.

First claim

What is claimed is:

1. An apparatus comprising:
a seismic streamer cable, wherein the cable has a bending stiffness of at least fifty Nm 2 ;
at least one seismic sensor; and
at least one rigid mount to secure said at least one seismic sensor to the streamer cable, the at least one rigid mount having a natural frequency higher than 150 Hertz.

2. The apparatus of claim 1 , wherein the at least one seismic sensor is fixed to the streamer cable using at least one of the following: gluing, welding, potting, casting and o-rings.

3. The apparatus of claim 1 , wherein the at least one sensor comprises at least one particle motion sensor.

4. The apparatus of claim 1 , wherein the at least one sensor comprises at least one pressure sensor.

5. The apparatus of claim 1 , wherein the streamer cable is adapted to be towed by a surface vessel.

6. A method comprising:
using a streamer cable to tow at least one sensor;
constructing the seismic cable to have a bending stiffness greater than fifty Nm 2 ; and
rigidly mounting the at least one sensor to the streamer cable, comprising mounting the at least one sensor to the cable using a mounting that has a natural frequency greater than 150 Hertz.

7. The method of claim 6 , wherein the rigidly mounting comprises mounting the at least one sensor using gluing, welding, potting, casting or an o-ring.
