Abstract: Various cables for cable deployed electric submersible pumping systems and methods of manufacturing such cables are provided. The cable includes a power cable core and coiled tubing formed around the power cable core. The power cable core includes one or more conductors, insulation surrounding each conductor, and an elastomeric jacket extruded around the insulated conductors. Various mechanisms, systems, and methods are described to anchor the power cable core in the coiled tubing and to transfer weight from the power cable core to the coiled tubing.

Abstract: A technique facilitates construction of a sealed electrical connector, e.g. sealed pothead assembly. Depending on the application, the electrical connector may be used to connect a power cable and a powered component such as an electric submersible pumping system. The electrical connector comprises at least one connector component and at least one electrical component. An injection molding process is used to construct an injection molded feature sealed to a corresponding component, e.g. to the at least one electrical component. The injection molded feature is readily formed and located between the at least one electrical component and the at least one connector component to form a simple and reliable seal which prevents unwanted passage of fluids.

Abstract: An electrical connector assembly for electric submersible pumps (ESPs) has a fluid impenetrable seal 3D-printed between the power cable and an internal housing component of the electrical connector assembly. Electrical insulation or dielectric for a conductor of the power cable may also be 3D-printed integrally with the fluid seal. The housing component, such as an internal electrical housing, may also be 3D-printed integrally with the printed seal. Likewise, in an implementation, the 3D-printed seal, the internal housing component, and an outer pothead case may all be 3D-printed as a unit onto the power cable. The 3D-printed seal and associated pothead components may be composed of a variety of chemical-resistant materials, such as printed polyarylether-ketones, printed fluorinated polymers, and metal alloys. The 3D-printed seal may also include barrier materials or reinforcement fillers to enhance strength and chemical resistance to well fluids and gases.

Abstract: An electric submersible pump system can include a shaft; a power cable connector for receipt of multiphase power; a multiphase electric motor configured to receive power via the power cable connector for rotatably driving the shaft; a pump operatively coupled to the shaft; and a power cable that includes a connector for connection to the power cable connector, a row multiphase conductors, a jacket surrounding the row of multiphase conductors that includes a polymer, and an outer coating that includes a fluoropolymer.

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.
