  • Artificial lift equipment power cables
    Patent number: 9336929
    Abstract: A power cable for artificial lift equipment can include one or more conductor assemblies, each including a copper conductor, a conductor shield with resistivity less than about 5000 ohm-m surrounding the conductor, insulation, an insulation shield having a resistivity less than about 5000 ohm-m surrounding the insulation, a metallic shield surrounding the insulation shield, and a polymer barrier surrounding the metallic shield. Such a cable may include a jacket molded about the one or more conductor assemblies and optionally armor surrounding the jacket. Various other apparatuses, systems, methods, etc., are also disclosed.

  • Tape adhesion test system
    Patent number: 9335249
    Abstract: Representative implementations of devices and techniques provide a tape adhesion test system. The test system applies a pulling force to an outer layer of tape adhered to an inner layer of tape through an adhesive bond, while the inner layer of tape is secured to a portion of the test system. The pulling force is measured when the adhesive bond between the outer layer of tape and the inner layer of tape breaks.
