ABSTRACT:
A borehole system for operating a downhole generator suspended on a composite coiled tubing string. The coiled tubing has at least two separate longitudinal chambers to provide separate flow paths. A fluid is pumped from the surface through one flowpath to drive a downhole turbine powered generator for operating downhole systems. A second flowpath in the tubing is used to return fluids to the surface. The non-metal environment of the composite coiled tubing provides a non-magnetic environment in which to operate wellbore devices. Data is transmitted to the surface by way of a fiber optic conductor.
