ABSTRACT:
There is provided a well completion for electrical alternating current power transmission that minimizes power losses and related corrosion problems. Casing is used both as the electrode and conductor. Most of the conductor portion is made of nonmagnetic metal, for example aluminum, and is electrically insulated both exteriorly and interiorly. The insulation extends below the point where the nonmagnetic metal ends. Tubing is used to produce or inject fluids. The upper end of the conductor-electrode may be surrounded by a nonmagnetic surface string which is also electrically insulated.
