    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.

    Abstract: A technique utilizes micro-coil which is formed as a composite to enable use at substantial depths and/or with substantial flow rates. The micro-coil is formed as a tubing with a multi-layered tubing wall. The composite tubing wall provides substantial strength and longevity which allows deployment of the micro-coil in a much wider variety of well treatment applications, such as applications having substantial flow rates and/or applications at substantial well depths.

    Abstract: Embodiments disclosed herein relate to a method and a system to deploy a downhole pump within a well. The system includes the downhole pump disposed in a well, the downhole pump having a motor, and a cable having at least one strength member layer bonded to a cable core, in which a first end is connected to a power source disposed at a surface of the well and a second end is connected to the downhole pump. The cable is configured to support and power the downhole pump in the well.

    Abstract: A powered fiber optic cable for use in a hydrocarbon well of extensive depth and/or deviation. The cable may couple to a downhole tool for deployment to well locations of over 30,000 feet in depth while maintaining effective surface communication and powering of the tool. The cable may be configured to optimize volume within a core thereof by employing semi-circular forward and return power conducting portions about a central fiber optic portion. As such, the cable may maintain a lightweight character and a low profile of less than about 0.5 inches in diameter in spite of powering requirements for the downhole tool or the extensive length of the cable itself.
