20150219776 | HYDROPHONE - This disclosure is related to hydrophones, for example hydrophones that may be used in marine seismic surveying, permanent reservoir monitoring, downhole acoustic monitoring in a wellbore, and/or various other applications. Some embodiments of a hydrophone according to this disclosure are constructed such that a longitudinal stiffness of the hydrophone is greater than a circumferential stiffness of the hydrophone. In some embodiments, however, the longitudinal stiffness may be somewhat less than the circumferential stiffness. For example, the longitudinal stiffness may be greater than one half the circumferential stiffness in some cases. | 08-06-2015 |
20160109596 | SENSOR RECEIVER NULLS AND NULL STEERING - A method. In one embodiment there is provided a method in which a direction from a sensor position to a noise source is determined. A coordinate rotation is applied to a first set of signal values, wherein each signal value of the first set of signal values is based on an output of a corresponding component of a three-component particle motion sensor at the sensor position. The applying generates a rotated set of signal values. The coordinate rotation comprises a coordinate rotation transforming a first set of coordinate axes to a second set of coordinate axes, wherein the first set of coordinate axes has each coordinate axis aligned with a corresponding component of the three-component particle motion sensor at the sensor position, and the second set of coordinate axes comprises a first axis pointed in a direction opposite the direction from the sensor position to the noise source. | 04-21-2016 |

20150234143 | SUBSEA CABLE HAVING FLOODABLE OPTICAL FIBER CONDUIT - In at least some embodiments, a disclosed subsea cable includes one or more floodable optical fiber conduits each having at least one tight buffered optical fiber for transporting optical signals. Each tight buffered optical fiber may have a relatively limited length. The subsea cable may further include multiple strength members contra-helically wound around or together with the one or more floodable optical fiber conduits. There may also or alternatively be included at least one hermetically sealed optical fiber conduit having at least one protected optical fiber spliced to one of the tight buffered optical fibers. At least some implementations splice each of the tight buffered optical fibers to corresponding protected fibers for the long-haul communications. Flooding of the floodable conduits may be provided via connectors at the subsea cable ends, via breakout locations where sensors are attached, and/or via vents in the conduit wall. Some method embodiments deploy the disclosed subsea cable designs in a body of water, putting the interior of at least one floodable optical fiber conduit in fluid communication with the body of water while supporting extended use for communicating signals, particularly in deep water where temperatures are relatively low. Because the floodable conduits have pressure-equalized interiors they may be formed from plastic or other materials that ease the process of attaching sensors to the subsea cables. | 08-20-2015 |
