| abstract |
The present invention relates to streamer cables. Various embodiments are directed to a streamer cable (100) comprising an outer skin (102), at least one sensor (108) positioned within the outer skin (102), and a solid void-filler material (112) positioned between the outer skin (102) and the at least one sensor (108), wherein the void-filler material (112) is coupled to the at least one sensor (108). The void-filler material (112) may partially or wholly encapsulate the sensor (108) and has mobility whereby to shift substantially all bulge wave energy outside of a desired signal frequency range. The void-filler material (112) may comprise a polymer, such as a thermoplastic polymer. The sensor (108) may be one of a directional sensor, a temperature sensor, a hydrophone, and a magnetic sensor. |
