Abstract: There is provided a solid seismic streamer cable for use in seismic surveying in marine environments. The streamer is characterized by a buffer layer 2 which is provided with a cut-out 50 and a sensor element arranged in the cut-out 50. There is also provided an associated hydrophone for integration into the seismic streamer cable. The hydrophone is characteristic in a split-element sensor base 10, 11 being suited for efficient mounting into the cut-outs 50 of the seismic cable. There is also provided an associated accelerometer for integration into the seismic streamer cable. The accelerometer is characteristic by a split-element sensor base 30, 35 for being efficiently arranged into the cut-outs 50 of the seismic cable. A method of producing a seismic streamer cable according to the invention incorporating a hydrophone or accelerometer according to the invention is also provided.

Abstract: A disclosed survey method includes towing geophysical survey streamers in a body of water and using sensors within the streamer to collect measurements that are then conveyed along the streamer to a recording station using at least one wireless transmission link. In some implementations at least one sensor is coupled to a wireless transceiver in a streamer to transmit geophysical survey measurement data along the streamer to a wireless base station. The base station receives the wirelessly transmitted seismic data and communicates it to a central recording station. Each segment of the streamer may contain a base station to collect wireless data from the sensors in that segment, and each base station may be coupled to the central recording station by wiring (e.g., copper or fiber optic). Other implementations employ ranges of sensors wired to local transceivers that form a peer-to-peer wireless network for communicating data to the central recording station.

Abstract: A method and apparatus for a seismic cable is described. In one embodiment, a method for performing a seismic survey in a water column is described. The method comprises providing a length of flexible cable from a cable storage device disposed on a vessel to a cable handling device adjacent the cable storage device. The flexible cable comprises a specific gravity that is greater than a specific gravity of water in the water column. The method further comprises routing the flexible cable to pass adjacent a workstation disposed on the vessel, deploying a free end of the flexible cable into the water column, attaching at least one of a plurality of seismic sensor units to the cable as the cable passes the workstation, and controlling the motion of the vessel and the rotational speed of the cable handling device to allow the flexible cable to rest on the bottom of the water column.
