Abstract: A technique enables protection of electrical conductors in a submerged environment, such as a wellbore environment. A connector system is deployed at the end of an electric cable to enable connection of the electric cable with a submersible component. The connector system comprises a connector body formed of a moldable material that is molded around at least one conductor of the electric cable. The moldable material insulates and protects the at least one conductor when the connector body is engaged with the submersible component.

Abstract: A technique is provided for connecting a power cable to a submersible component. A connector system is used to form the connection and comprises a plurality of individual connectors for connecting power carrying conductors to the submersible component. Each of the individual connectors is separately connectable to the submersible component which enables improved sealing with respect to the submersible component. In multi-phase power applications, individual connectors can be used for each phase.

Abstract: One or more silica optical fibers (22), especially for use in downhole distributed temperature sensing and similar applications, are deployed in a corrosion resistant metal alloy control line (20) which is electrically insulated with, for example, EPDM. The insulation layer may be covered by a fluid resistant sealing layer (26), which may in turn be covered by a mechanical armor layer 28. The resultant composite optical fiber cable exhibits improved resistance to degradation of optical performance at elevated temperatures over about 100 deg. C.

Abstract: A submersible pumping system for use in high temperature, wellbore applications. The system includes an electric submersible pumping unit, having at least a submersible motor, a motor protector and a submersible pump powered by the submersible motor. A uniquely designed power cable is coupled to the submersible motor to provide power thereto. The unique design of the power cable and its connector permit the use of the overall system in high temperature environments or applications where the system is exposed to high temperature conditions.
