ABSTRACT:
A system for providing large quantities of power at a selected voltage to a downhole well tool. A conductor extends between a surface regulator and the well tool. The voltage is continuously measured downhole at the well tool, and a signal proportional to such downhole voltage is transmitted to the surface regulator. The power transmitted by the surface regulator to the conductor is increased or decreased depending on fluctuations in the tool requirements and the downhole voltage. The downhole voltage signal can be modulated through the conductor to the surface regulator or can be transmitted through another conductor.
