  • Publication number: 20160329128
    Abstract: A torque-balanced, gas-blocking wireline cable and a method of making the cable includes an electrically conductive cable core for transmitting electrical power and surrounding inner and outer layers of a plurality of armor wires. Gas blocking is achieved by placing a soft polymer layer over the core before the inner wires are cabled thereon. The inner wires imbed partially into the soft polymer layer such that no gaps are left between the inner wires and the core. A second soft polymer layer is optionally extruded over the inner wires before the outer wires are applied. The second soft polymer layer fills any spaces between the inner and outer wire layers and prevents pressurized gas from infiltrating between the wires. The inner wires have larger diameters than the outer wires such that the inner wires carry approximately 60% of the load and torque imbalance is prevented.

  • Publication number: 20160293298
    Abstract: A technique for manufacturing slickline with a jacket of enhanced bonding. The technique may include roughening an outer surface of a metal core and applying an initial insulating polymer layer to the roughened core in a non-compression manner such as by tubing extrusion. The insulated core may then be heated and run through a set of shaping rollers. Thus, the grip between the polymer and the underlying metal core may be enhanced at a time following the initial placement of the polymer on the core. In this manner, processing damage to the underlying core surface which might adversely affect maintaining the grip may be minimized. Other techniques such as powder spray delivery of the initial polymer layer may also be utilized in a similar manner.

  • Patent number: 8913863
    Abstract: A hydrocarbon application cable of reduced nylon with increased flexibility and useful life. The cable may be of a hose or solid configuration and particularly beneficial for use in marine operations. A power and data communicative core of the cable may be surrounded by a lightweight intermediate polymer layer of a given hardness which is ultimately then surrounded by an outer polymer jacket having a hardness that is greater than the given hardness. Thus, a lighter weight polymer is provided interior of the outer polymer jacket, which may be of nylon or other suitably hard material. As such, the overall weight and cost of the cable may be substantially reduced.
