Abstract: The embodiments of the present disclosure relate to a thermally-insulated conduit (TIC) for use in conducting fluids from a first location to a second location. The TIC a metal conduit; and at least a first layer of a thermal-insulation material (TIM) that is operatively coupled to the metal conduit for preventing transfer of some, substantially most or all thermal energy between inside the conduit and outside the conduit.

Abstract: A submersible downhole pumping system is provided. The pumping system is designed so that all fluid conduits and electrical signal conduits are internalized within a pumping assembly. This design provides a substantially constant and slim profile to the pumping assembly. The pumping assembly comprises a housing that houses a power assembly, a powered actuator assembly that is operatively linked to a production fluid assembly and a central bore that extends through the pumping assembly to provide fluid communication between the power assembly and a first end of the pumping assembly. The pumping system further includes a flow distributor/connector at the first end or pump head for providing fluids' communication between the pump head and a conducting system that extends from surface to the pumping system. The communication fluids include high pressure power hydraulic fluid, low pressure exhaust hydraulic fluid and pressurized produced wellbore fluid.
