3. The system of claim 2 , wherein the power conductor comprises at least one of an electrical power conductor or a hydraulic power conductor.

4. The system of claim 2 , wherein the data conductor comprises at least one of a fiber-optic cable or an electrically conductive cable.

5. The system of claim 1 , wherein the spoolable composite pipe comprises:

an outer protective layer enclosing the composite layer and inner liner, wherein the composite layer comprises high strength fibers.

6. The system of claim 5 , wherein the at least one energy conductor is at least one of (i) embedded within at least one layer of the spoolable composite pipe, (ii) helically wound around at least one inner layer of the spoolable composite pipe, or (iii) extended substantially parallel with an elongate axis of the spoolable composite pipe.

7. The system of claim 1 , wherein the spoolable composite pipe comprises at least one reinforcing element.

8. The system of claim 1 , wherein the at least one fluid separation device further comprises at least one of a measurement device or a communication device.

9. The system of claim 8 , wherein the measurement device comprises at least one of a flow meter, a pressure meter, a temperature meter, a stress meter, a strain gauge, and a chemical composition measuring device.

10. A method of separating fluids at a below ground location in a wellhole, comprising:

positioning at least one separation device comprising at least one pump at a below ground location in a wellhole;

connecting the at least one separation device to an above-ground location through a spoolable composite pipe comprising a fluid channel defined by a composite layer enclosing a substantially fluid impervious inner layer and at least one energy conductor via a distal mounting comprising a central path and at least one outer path, the distal mounting adapted to couple a distal end of the fluid channel to the at least one pump by passing the composite layer and the inner layer completely through the central path;

providing at least one of a power supply or a control signal to the at least one separation device through the at least one energy conductor extending completely through the at least one outer path exclusive of the central path;

passing a fluid mixture through the at least one fluid separation device;

separating the fluid mixture into at least one first fluid and at least one second fluid;

pumping the first fluid to the surface through the fluid channel; and

releasing the second fluid to an underground formation.

11. The method of claim 10 , wherein the first fluid comprises at least one of oil-rich fluid and a gas-rich fluid.

12. The method of claim 10 , wherein the second fluid comprises a water-rich fluid.

13. The method of claim 10 , wherein the at least one fluid separation device is connected to the spoolable composite pipe prior to positioning the at least one fluid separation device at the below ground location in the wellhole.

14. The method of claim 10 , wherein the energy conductor comprises at least one of a power conductor and a data conductor.

15. The method of claim 10 , wherein both power supply and control signals are provided to the at least one fluid separation device through separate energy conductors.
