    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.

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.

  • Patent number: 8563864
    Abstract: A smooth-bore plastic tubing with an outer helical support bead is resistant to collapse and incorporates plural conductors disposed outside of the tubing bore and insulated both from ambient and from one another. The conductors may have a desired relatively high thermal conductivity to tidal air flow within the tubing, while also having a comparatively high thermal resistance to ambient. The conductors may be electrical conductors, or may include fiber optic conductors as well in the same tubing structure. A method for making the tubing includes extruding a molten thermoplastic ribbon. The plastic ribbon is wrapped to form a tubular body, and a grooved plateau portion is wrapped upon the tubular body. At least one conductor is embedded in the groove of the plateau portion.
