Well completion with single wire guidance system

Abstract

The present disclosure includes a system. The system includes a current source and a ground terminal The ground terminal is electrically connected to the current source. The ground terminal is grounded at the surface of the Earth. The system further includes a reference conductor. The reference conductor is electrically connected to the current source, and the reference conductor is inserted into a reference wellbore. The system further includes a tubular. The tubular includes a tubular string electrical discontinuity, and the tubular is inserted into the reference wellbore. The tubular has a tubular bottom hole end, and the tubular is electrically conductive between the electrical discontinuity and the bottom hole end. The system further includes an electrical connection between the tubular and reference conductor between the tubular string electrical discontinuity and the tubular bottom hole end. The system also includes an electrical connection between the tubular and the reference wellbore between the tubular string electrical discontinuity and the tubular bottom hole end. The system further includes magnetic sensors located outside the reference wellbore.
