Abstract: Seismic hydrophone streamer assemblies are constructed utilizing hydrophones which comprise cylindrical segments of crystals disposed with the axis of the crystals transverse to the axis of the streamer cable. This construction permits usage of a crystal having a diameter significantly larger than the diameter of the cable regardless of whether the crystal is disposed internally of a streamer cable. A crystal mounting means is provided which can be affixed to the exterior of a central stress member streamer cable and which supports the crystal solely by the edge of the crystal segment parallel to the cylindrical axis of the cylinder.

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 pressures below about 300 psi to avoid bursting the gas filled spheres of the syntactic foam.
