Abstract
A well completion system includes a current source, a ground terminal, and a reference conductor. The reference conductor is electrically connected to the current source, and is inserted into a reference wellbore having a tubular therein. The tubular has a tubular bottom hole end, and the tubular is electrically conductive between an electrical discontinuity and the bottom hole end. The tubular between the tubular string electrical discontinuity and the tubular bottom hole end is electrically connected to the reference conductor. The tubular between the tubular string electrical discontinuity and the tubular bottom hole end is electrically connected to the reference wellbore. Magnetic sensors are located outside the reference wellbore.
