Publication number: 20180058193Abstract: A drilling area network hub is located proximate to a drill rig and includes an uphole transceiver in bidirectional communication with a downhole transceiver by utilizing the drill string as an electrical conductor. Certain information is collected including rig-based and/or location information. At least one field report is generated based on the certain information to characterize at least one of an inground operation, an operational condition of the downhole transceiver, an operational condition of the uphole transceiver, and an operational condition of the drill rig. A drilling area network server receives the field report from the Internet at a remote location and can generate a custom report and/or recommended actions based on field data. Region specific parameters can be applied to the operation of a drilling system. The drilling area network hub can transfer data logs to the remote location according to assigned priorities.Type: ApplicationFiled: October 24, 2017Publication date: March 1, 2018Inventor: Thomas J.

Publication number: 20180058196Abstract: Systems and methods for distributed acoustic sensing based on coherent Rayleigh scattering are disclosed herein. A system comprises a pulse generator, an interferometer, a photo detector assembly, and an information handling system. The interferometer comprises a first and second optical switch each comprising a plurality of ports. The information handling system activates one port on each of the first and second optical switches so as to vary the optical path length of the interferometer. A method comprises splitting backscattered light from an optical pulse into a first portion and a second portion, activating one port of a first optical switch and one port of a second optical switch, sending the first portion into a first arm of an interferometer, sending the second portion into a second arm of the interferometer, combining the first and second portions to form an interferometric signal, and receiving the interferometric signal at a photodetector assembly.Type: ApplicationFiled: October 30, 2017Publication date: March 1, 2018Inventors: Mikko Jaaskelainen, Kwang Il Suh, Ira Jeffrey Bush

Publication number: 20180058197Abstract: Distributed optical sensing systems utilize compressive sensing techniques to determine parameters sensed by a waveguide. The system generates light that is sent along a sensing waveguide, thereby producing backscattered light. A compressive sampling filter forms part of the system, and is used to selectively block portions of the generated light or the backscattered light. The backscattered light is received by a receiver and used to determine one or more parameters.Type: ApplicationFiled: December 28, 2015Publication date: March 1, 2018Inventors: David Andrew Barfoot, Safyan Gopal Bhongale, Christopher Lee Stokley, Andreas Ellmaufhaler
