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 method of measuring the temperature in a wellbore may include positioning a conductor within the wellbore where the conductor has a temperature-dependent resistivity. By measuring the resistance of the conductor, the temperature of the wellbore may be determined. The conductor may be coupled to a power supply by a wireline. The resistivity of the wireline may be measured or calibrated for changes in its resistivity in response to wellbore temperature.

摘要： 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.
