ABSTRACT:
An apparatus and method for communicating electricity from a well surface to a downhole well tool. An electrical conductor is positioned within a sheath, and fluid is placed within a passage extending through the sheath. Electricity is transmitted to the well tool through the conductor, and the fluid prevents well fluid intrusion into the sheath interior. The fluid can be pressurized from the well surface to communicate hydraulic fluid pressure to the well tool and to provide structural rigidity to the cable system. A diverter between the sheath and the well tool can selectively direct electricity or hydraulic fluid pressure to selected portions of the well tool, or to other tools positioned in the well.
