Abstract: Techniques are disclosed relating to the determination of a warping attribute related to a difference between an up-going pressure wavefield and a down-going pressure wavefield received from a seismic data acquisition system. The warping attribute is used to determine a pseudo up-going or down-going pressure wavefield. The pseudo pressure wavefield is used to generate a modified record of geophysical data, which is stored in a non-transitory memory medium as a geophysical data product.

Abstract: Method and apparatus for mitigating vibrations in a device towed in water. The apparatus includes one or more tuned elastic sections having a complex spring rate and adapted to attenuate vibrations in a specified frequency range; and a head end coupler adapted to couple the apparatus for vibration mitigation to a component of an electro-mechanical cable or a tow assembly. One of the one or more tuned elastic sections is coupled to the head end coupler with a high impedance material interface.

Abstract: Marine geophysical damper system. At least some of the example embodiments are methods of manufacturing a geophysical data product including obtaining geophysical data by a sensor streamer; and recording the geophysical data on a tangible computer-readable medium. The obtaining may include: towing a sensor streamer and a dilt buoy, the dilt buoy coupled to a proximal end of the sensor streamer by a line, the sensor streamer is submerged in a body of water and the dilt buoy is disposed at the surface the body of water; and during the towing measuring movement of the dilt buoy caused by surface wave action; and selectively damping relative movement between the dilt buoy and the sensor streamer, the relative movement caused by the surface wave action, and the selectively damping by a damper associated with the line.

Abstract: This disclosure presents a streamer filler material that is a low density gel formed from a two-part, mix-curable polymer, and methods of making streamers using such materials. One embodiment of the filler material features a two-part silicone gel mixed with a paraffinic oil. The two-part silicone gel can make up 15% to 25%, by weight or volume, of the mixture. Methods of making such materials include forming a first unreactive mixture having a first reactant, promoter, and/or catalyst and a second unreactive mixture having a second reactant, promoter, and/or catalyst and mixing the first and second mixtures in a paraffinic oil system to make a gel. The streamer can be loaded with the filler by pumping or extruding the mixture.

Abstract: A method of manufacturing a streamer section. The method includes coupling together a plurality of prefabricated harness modules. A harness module includes a plurality of geophysical sensors disposed along a length of the harness module and a sensor node communicatively coupled to the plurality of sensors. A first connector is disposed at a first end of the harness module and a second connector disposed at a second end of the harness module. The first connector is coupled to the sensor node and is configured to couple to a second harness module and receive data from a sensor node in the second harness module. The second connector is coupled to the sensor node and is configured to couple to a third harness module and forward data to a sensor node in the third harness module.
