    Abstract: Tubing encapsulated cable consists of one or more electrical conductors and possibly one or more fiber optic cables sheathed in a corrosion resistant metallic alloy. However, pumping during the installation of tubing encapsulated cable is required to overcome the capstan effect of the tubing encapsulate cable inside the coil tubing as the tubing encapsulated cable travels through the coiled up wraps of coil tubing. In an embodiment of the invention the tubing encapsulated cable consists of one or more electrical conductors and possibly one or more fiber optic cables sheathed in a fiber reinforced composite sheath. Because there is little drag between the fiber encapsulated cable and the coil tubing, conventional pumping operations used to install braided wireline into coil tubing may not be required when installing fiber encapsulated cable into coil tubing.

  • Patent number: 9704617
    Abstract: A production method for a headline sonar cable (20, 120) that exhibits a high breaking-strength and lighter weight than a conventional steel headline sonar cable. Producing the headline sonar cable (20, 120) is characterized by the steps of: a. providing an elongatable internally-located conductive structure (34, 134) that is adapted for data signal transmission; and b. braiding a strength-member jacket layer (52) of polymeric material around the structure (34, 134) while ensuring that the structure (34, 134) is slack when surrounded by the jacket layer (52). The structure (34, 134) of the cable (20, 120) retains conductivity upon stretching of the jacket layer (52) surrounding the structure (34, 134) that lengthens the cable (20, 120). For one embodiment of the method a conductor (20) wrapped around a rod (24) and enclosed within a sheath layer (32) forms the structure (34, 134).
