Abstract
Systems and methods for cable deployment of downhole equipment, wherein the conductors of a power cable bear the load of the downhole equipment and jewelry, as well as the cable itself. The power cable includes a set of elongated conductors, an upper coupling and a lower coupling. The upper support coupling suspends each of the conductors from the support structure and electrically couples the conductors to a power source. The lower coupling suspends the downhole electrical equipment from the conductors and electrically couples the conductors to the downhole equipment. One embodiment uses 7075 T-6 aluminum conductors to provide a length of at least 10,000 feet, a yield stress of at least 50,000 psi and a resistance of less than 0.2 ohm/kf. The aluminum conductors are homogeneous and are non-reactive with hydrogen sulfide, so no lead sheathing is required.
