Seismic Sensor Cable

1 . A seismic streamer, comprising:

an outer skin formed in a longitudinally extending tubular shape, an inner surface of the outer skin defining an internal volume;

a strength member that extends through the internal volume in a direction parallel to that of the longitudinally extending tubular shape;

a filler material disposed in the internal volume; and

a sensor housing internally disposing a seismic sensor, the sensor housing located in the internal volume.

2 . The seismic streamer of claim 1 , wherein the filler material comprises one or more of a gas, liquid, gel or foam.

3 . The seismic streamer of claim 1 , wherein the sensor housing is supported in the internal volume by the filler material.

4 . The seismic streamer of claim 1 , wherein the sensor housing comprises a buoyancy element attached thereto, whereby the sensor housing is substantially neutrally buoyant in the filler material.

5 . The seismic streamer of claim 1 , wherein the sensor housing is disposed between a pair of spacer devices that support the outer skin.

6 . The seismic streamer of claim 1 , wherein the sensor housing is disposed between a pair of spacer devices that support the outer skin; and

the filler material between the pair of spacer devices comprises a foam.

7 . The seismic streamer of claim 1 , further comprising a sensor spacer device located within the internal volume having an outer radius that is substantially similar to the inner radius of the inner surface of the outer skin, wherein the sensor housing is co-located with the sensor spacer device.

8 . The seismic streamer of claim 7 , wherein the sensor housing extends from opposite sides of the sensor spacer device.

9 . The seismic streamer of claim 7 , wherein the seismic sensor is one of coupled or decoupled from the strength member.

10 . The seismic streamer of claim 9 , wherein the sensor spacer device is connected to the strength member.

11 . The seismic streamer of claim 7 , wherein the sensor housing is disposed in a passage of the sensor spacer device and the sensor housing physically engages the sensor housing.

12 . The seismic streamer of claim 7 , wherein the sensor spacer device is disposed in a passage through the sensor spacer device and the sensor housing is physically separated from the sensor spacer device.

13 . The seismic streamer of claim 12 , wherein the sensor housing comprises a buoyancy element attached thereto.

14 . A method, comprising disposing in an internal volume of an outer skin of a seismic streamer a longitudinally extending sensor housing that internally carries a seismic sensor.

15 . The method of claim 14 , comprising supporting the sensor housing in a filler material.

16 . The method of claim 15 , wherein the sensor housing is located between a pair of spaced apart spacer devices that support the outer skin.

17 . The method of claim 14 , wherein the sensor housing is co-located with a sensor spacer device having an outer radius that is substantially similar to the inner radius of the inner surface of the outer skin.

18 . The method of claim 14 , wherein the sensor housing is disposed in a passage of the sensor spacer device and the sensor housing physically engages the sensor housing.

19 . The method of claim 14 , wherein the sensor spacer device is disposed in a passage through the sensor spacer device and the sensor housing is physically separated from the sensor spacer device.

20 . A seismic sensor unit for use in a seismic streamer, comprising:

an elongated enclosed housing;

an accelerometer disposed inside of the elongated housing; and

sensor electronic connected to the accelerometer and disposed inside of the elongated housing.
