摘要： An artificial toolface reference system includes a power supply providing current to a ground lead and a reference lead. A ground point is coupled to the ground lead and in electrical connection with the ground. A reference wellbore includes a reference conductor in electrical connection with the ground. The reference conductor is in electrical connection with the reference lead. A guidance sensor positioned outside the reference wellbore includes at least one magnetometer. The power supply may be used to provide a current through the reference conductor, the ground, and the ground point such that a reference magnetic field is generated along the reference conductor. The guidance sensor may measure the reference magnetic field with a magnetometer. An artificial magnetic toolface may be calculated therefrom.

摘要： An artificial toolface reference system includes a power supply providing current to a ground lead and a reference lead. A ground point is coupled to the ground lead and in electrical connection with the ground. A reference wellbore includes a reference conductor in electrical connection with the ground. The reference conductor is in electrical connection with the reference lead. The reference conductor includes an uninsulated portion and an insulated portion having an insulating layer positioned thereabout. A guidance sensor positioned outside the reference wellbore includes at least one magnetometer. The power supply may be used to provide a current through the reference conductor, into the ground through the uninsulated portion, and the ground point such that a reference magnetic field is generated along the reference conductor. The guidance sensor may measure the reference magnetic field with a magnetometer. An artificial magnetic toolface may be calculated therefrom.

摘要： A system includes a current source and a ground terminal. The ground terminal is electrically connected to the current source and is grounded at the surface of the Earth. The system further includes a reference conductor, which is electrically connected to the current source and a tubular, which includes a tubular string electrical discontinuity; the reference conductor and tubular are inserted into a reference wellbore. The tubular has a tubular bottom hole end, and is electrically conductive between an electrical discontinuity and a 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.
