  • TORQUE-BALANCED, GAS-SEALED WIRELINE CABLES
    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.

  • SLICKLINE MANUFACTURING TECHNIQUES
    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.

  • Electrically Conductive Fiber Optic Slickline For Coiled Tubing Operations
    Publication number: 20160222736
    Abstract: A slickline that includes both electrically conductive and fiber optic capacity. The slickline includes a fiber optic thread or bundle of threads that may be surrounded by an electrically conductive member such as split half shells of copper elements. Further, these features may be disposed in a filler matrix so as to provide a cohesiveness the core of the slickline. So, for example, the line may be more effectively utilized in downhole applications such as coiled tubing operations, without undue concern over collapse or pinhole issues emerging in the line.

  • DEPLOYMENT AND RETRIEVAL SYSTEM FOR ELECTRIC SUBMERSIBLE PUMPS
    Publication number: 20160186507
    Abstract: Representative implementations of devices and techniques provide a system arranged to deploy and retrieve a device such as an electric submersible pump with respect to a well or other like formation.

Modification to the tube injection device may include addition of cable-gripping blocks to the injection components. Multiple injection devices can be utilized to open and close in coordination in order to let a large connector or termination on the cable pass through an open injector while a closed injector maintains a grip on the cable.
