Abstract: A neutrally buoyant seismic hydrophone streamer is constructed by extruding a syntactic foam material comprising an elastomeric material and gas filled microspheres onto a central stress member to form an elongated streamer member. The streamer may then be covered with a suitable water and oil resistant, abrasion resistant covering and be provided with exteriorly affixed hydrophones, or hydrophones can be affixed to the foam core and an outer protective sheath can be extruded or otherwise provided around the streamer and the hydrophones to provide a uniform diameter streamer assembly. Extrusion is effected utilizing a suitable elastoplastic material which can be extruded at temperatures below about 300 psi to avoid bursting the gas filled spheres of the syntactic foam.

Abstract: A hydrophone assembly for use in a marine streamer having a cable core includes a piezoelectric crystal in the form of a cylinder that is mounted in concentric relation on the cable core by cap assemblies. Each cap assembly is formed in two separate halves that can be fitted together and sealed with respect to the cylinder and core after the crystal is in place and has been connected to the electrical conductors inside the core.

Abstract: A marine streamer cable of layered solid construction and having substantially the same composition density as sea water, comprising a flotation layer surrounding a cable core having as a central stress member a polypropylene rope made with paralleled fibers held together by an extruded plastic jacket, the use of which minimizes the weight of the cable and serves to greatly attenuate the propagation along the cable of mechanical noise.
