Abstract
An apparatus includes a streamer having one or more seismic data acquisition devices enclosed within a skin. The skin has a modulus of elasticity of at least 30 MPa to attenuate a flow noise.
Claims17
An apparatus, comprising:
- a streamer having seismic data acquisition devices enclosed within a skin, the skin having a modulus of elasticity of at least 30 MPa;
- the seismic data acquisition devices comprising a multi-component seismic sensor, the seismic data acquisition devices being supported within a filler material that is supported within and in contact with an inside surface of the skin, wherein the modulus of elasticity of the skin is selected according to the type of filler material to reduce turbulent noise within the streamer.
A seismic spread, comprising:
- a streamer for use in seismic data acquisition, the streamer comprising:
- a skin having a modulus of elasticity of at least 30 MPa;
- a gel filler material supported within the skin;
- one or more seismic data acquisition devices enclosed with the gel filler material, the one or more seismic data acquisition devices comprising a multi-component seismic sensor, the modulus of elasticity of the skin being selected according to the type of gel filler material to reduce turbulent noise within the streamer;
- and
- a vessel for towing the streamer.

an apparatus, comprising:
- a streamer having one or more seismic data acquisition devices enclosed within a skin, the skin having a modulus of elasticity of at least 30 MPa;
- a filler material supported within the skin during use of the streamer;
- and
- the skin having longitudinally extending ribs on an inner surface of the skin, wherein the skin and the ribs of the skin are together an uninterrupted material in a radial direction, the ribs being arranged to facilitate flexing of the skin under pressure in a manner which also dampens pressure waves produced during stretching of the streamer.
