Abstract
A seismic streamer includes a jacket covering an exterior of the streamer. At least one strength member extends along the length of and disposed inside the jacket. At least one seismic sensor is mounted in a housing affixed to the at least one strength member. A void filling material fills the interstices inside the jacket. The housing is configured to isolate the at least one sensor from pressure variations in the void filling material, and the housing is configured to couple the at least one sensor to a body of water outside the streamer.

A seismic streamer, comprising:
- a jacket covering an exterior of the streamer;
- at least one strength member extending along the length of and disposed inside the jacket;
- at least one housing affixed to the at least one strength member;
- at least one seismic sensor mounted proximate the center of the housing, the housing includes two longitudinally spaced apart end plates and a support structure disposed therebetween, the support structure maintaining the end plates in respective longitudinal position, the support structure defining a chamber in pressure communication with the fluid in which the streamer is disposed, the sensor disposed in the chamber;
- and
- a void filling material filling interstices inside the jacket, the housing configured to isolate the at least one sensor from pressure variations in the void filling material, the housing configured to pressure couple the at least one sensor to a body of water outside the streamer, the at least one strength member laterally displaced from the center of the housing and pressure isolated from the at least one sensor.
