Abstract: Methods and apparatus are described for reducing noise in measurements made by one or more pressure sensors disposed in a cable having a generally longitudinal axis. Estimated axial vibration noise at a location along the cable is determined based at least in part on measurements from one or more motion sensors disposed along the cable. The estimated axial vibration noise is subtracted from pressure sensor measurements corresponding to the location. The result is noise-attenuated pressure sensor measurements corresponding to the location.

Abstract: Marine survey data can be acquired at a tow line. The tow line is designed to be coupled between a marine survey vessel and a towed object. A receiver is associated with the tow line and designed to receive marine survey data at a location of the tow line. The receiver can be an optical fiber or other type of receiver.

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 seismic pressure and acceleration sensor can include a hydrophone having a volume encapsulated by an enclosure. The enclosure can include, a pressure-sensitive surface and a pressure-insensitive support structure. The sensor can also include an accelerometer positioned within the encapsulated volume. The accelerometer is mechanically isolated from the pressure-sensitive surface and mechanically coupled to the pressure-insensitive support structure.

Abstract: Included are methods and apparatus for marine geophysical surveying. One embodiment of the presently-disclosed solution relates to a method for instantaneous roll compensation of vectorised motion data originating from a fixed-mount geophysical sensor during a marine seismic survey. A streamer is towed behind a survey vessel in a body of water. The streamer includes a plurality of geophysical sensors and a plurality of orientation sensor packages. Vectorised geophysical data is acquired using the plurality of geophysical sensors, while orientation data is acquired by the plurality of orientation sensor packages. The orientation data is used to determine an instantaneous roll angle of the streamer at different positions on the streamer. The vectorised geophysical data is adjusted to compensate for the instantaneous roll angle of the streamer at different positions on the streamer. Other embodiments and features are also disclosed.

Abstract: A system for ocean bottom sensing for performing geological survey. Herein the system comprising a cable further comprising a cable jacket (9), at least one optical fiber (6), and a plurality of detectors enclosed by the cable jacket (9). The latter including at least a first and a second detector (1, 2), the at least first and second detector (1, 2) comprising at least one intrinsic fiber optic sensor (3x, 3y, 3z, 3h, 3g, 3t). The detectors are communicatively connected to the at least one optical fiber (6) for allowing interrogation of the intrinsic fiber optic sensors (3x, 3y, 3z, 3h, 3g, 3t) and the cable jacket (9) has substantially a same cross-sectional diameter (D) and same outer shape at the at least first and second detector (1,2) and in between said first and second detector (1,2).

Abstract: Embodiments, including apparatuses, systems, and methods, for attaching autonomous seismic nodes directly to a deployment cable. The nodes may be attached to the deployment cable by a removable fastener or insert. The fastener may be a staple that surrounds the cable and rigidly couples to the node to securely fasten the cable to the node. The fastener may be secured into the node itself, a housing or enclosure surrounding the node, or into a receiver or mechanism attached to the node. Other fasteners besides a staple may include bands, wires, pins, straps, ties, clamps, and other similar devices that may be inserted around a portion of the deployment line and be removably coupled to the node. After retrieval of the node, the fastener may be removed and discarded.

Abstract: A system can include a first array of hydrophones and a second array of hydrophones. Each of the hydrophones can include a first detector and a second detector. A sensitivity of the first detector can be matched with a sensitivity of the second detector and a combined sensitivity of the first array of hydrophones can be matched with a combined sensitivity of the second array of hydrophones.
