  • Patent number: 11320614
    Abstract: A fiber optic cable includes a plurality of optical fibers and an optical sensor. The optical sensor includes a first optical coupler and a first mirror. The first optical coupler is coupled to a first of the optical fibers and to a second of the optical fibers at a first sensor takeout location. The first mirror is coupled to the first of the optical fibers at a second sensor takeout location. The first sensor takeout location is longitudinally offset from the second sensor takeout location.

  • Patent number: 11243316
    Abstract: A housing for a seismic sensor station has a base and a removable lid, which when assembled together form a shell whereby the base and the removable lid both have a shell side and an exterior side. A sensor spike, protruding outward from the shell, may be attached to the base on the exterior side of the base. The housing is further provided with two cable docking ports, each allowing passage of a fiber optical cable from outside to inside the shell. The two cable docking ports are exclusively provided in the removable lid.

  • Patent number: 10705232
    Abstract: An integrated seismic system and method for monitoring seismic parameters of a subsurface structure is provided. The integrated seismic system includes a base station; a plurality of mobile satellite nodes, each of the plurality of mobile satellite nodes having sensor stations for collecting seismic data from the subsurface structure; and a fiber optic cable extending from the base station to the plurality of mobile satellite nodes and operatively linking the plurality of mobile satellite nodes and the sensor stations; the base station comprising: a light source for sending a light through the fiber optic cable, the light being distributed to the sensor stations and, in the sensor stations, experiencing a change or phase shift related to a physical property being measured; and a seismic acquisition unit for receiving seismic signals from the plurality of mobile satellite nodes via the fiber optic cable and generating seismic parameters therefrom.

  • Patent number: 9664805
    Abstract: A system and method for handling seismic cable having sensor stations thereon is provided. The seismic cable is positionable about the seismic field for measuring seismic parameters of a subsurface structure. The system includes a mobile unit, a reel and a winch assembly. The mobile unit is positionable about the seismic field, and has a platform. The reel is supportable on the platform with the seismic cable disposable about the reel. The winch assembly is carried by the mobile unit and includes a plurality of cable guides. At least one of the cable guides has a passageway with an adjustable dimension for aligning and guiding the seismic cable and the sensor stations passing therethrough.
