A technique is provided to facilitate monitoring of contaminants which can potentially enter an electric submersible pumping system. A sensor system is used in conjunction with the electric submersible pumping system to detect the presence of specific contaminants which can affect future operation of the electric submersible pumping system. Depending on the embodiment, the sensor system may comprise a sensor or sensors disposed within the electric submersible pumping system and/or in or along components associated with the electric submersible pumping system. Each sensor is used to monitor for the contaminant and to provide data to a control system so as to facilitate decision-making regarding future operation of the electric submersible pumping system.

ESP monitoring system and methodology

A submersible component can include a conductor; and a polymeric material disposed about at least a portion of the conductor where the polymeric material includes at least approximately 50 percent by weight polyether ether ketone (PEEK) and at least 5 percent by weight perfluoroalkoxy alkanes (PFA). A submersible electrical unit can include an electrically conductive winding; and a polymeric composite material disposed about at least a portion of the electrically conductive winding where the polymeric composite material includes polymeric material at at least approximately 40 percent by volume and one or more fillers at at least approximately 10 percent by volume.

Polymeric materials

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.

Cables for cable deployed electric submersible pumps

A method can include extruding polyethylene about a lead (Pb) barrier layer disposed about a conductor to form an assembly; and armoring at least one of the assemblies with metallic armor to form a cable. A power cable can include a conductor; a lead (Pb) barrier layer disposed about the conductor; a cushion layer disposed about the lead (Pb) barrier layer where the cushion layer includes crosslinked polyethylene (XLPE); and metallic armor wrapped about the cushion layer.

Armored submersible power cable

An electric submersible pumping system cable is provided with a plurality of conductors. The electric submersible pumping system cable includes at least one central strength member which may be in the form of a central strength member bundle. The plurality of conductors may be in the form of a plurality of individually insulated conductors arranged about the central strength member. The electric submersible pumping system cable also may include a jacket layer disposed over the insulated conductors.

Alternate deployed electric submersible pumping system cable

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.

High-temperature injection molded electrical connectors with bonded electrical terminations

A technique facilitates forming couplings along a power cable used, for example, to supply power to an electric submersible pumping system. In coupling the power cable to the electric submersible pumping system, a pothead may be provided with individual pothead bodies connected to individual conductors of the power cable. The pothead bodies are held with respect to each other by a plate structure which may be readily secured to a submersible motor of the electric submersible pumping system. If splices are formed along the power cable, individual potheads may be secured to conductor ends of the sections of power cable. The conductor ends are then inserted into corresponding individual adapters in a manner forming a secure and sealed connection.

System and methodology for power cable coupling

A technique facilitates construction and operation of a power cable which may be used to deploy an electric submersible pumping system downhole into a wellbore. The power cable is constructed to provide structural support of the electric submersible pumping system while also providing electric power to the electric submersible pumping system when located downhole in the wellbore. The power cable has at least one conductor and a plurality of layers selected and arranged to ensure long-term support and delivery of electrical power in the relatively harsh downhole environment.

Power cable for cable deployed electric submersible pumping system

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.

3D-printed seals and connectors for electric submersible pumps

An electric submersible pump motor can include a housing; and a hermetically sealed cavity defined at least in part by the housing that includes at least one material susceptible to hydrolysis, and a polymeric material that includes epitaxial co-crystals of perfluoroalkoxy (PFA) and polytetrafluoroethylene (PTFE). Various other apparatuses, systems, methods, etc., are also disclosed.

Equipment including epitaxial co-crystallized material

An electrical power cable for high temperature environments comprises two or more sheathed conductors; each sheathed conductor comprising an electrical conductor, an electrical insulator surrounding the electrical conductor, and a sheath surrounding the electrical insulator; and a bonding material interconnecting the sheaths of the two or more sheathed conductors positioned adjacent to one another to form a cable.

Power cable for high temperature environments

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.
