Abstract:
A system for ranging between two wellbores. The target wellbore includes a conductive body (e.g., casing) disposed within a portion of the target wellbore. A second wellbore includes an electromagnetic field sensing instrument positioned within the wellbore. A current delivered to the conductive body in the target wellbore results in a magnetic field emanating from the target wellbore. The electromagnetic field sensing instrument is utilized to measure an electromagnetic gradient based on the magnetic field, which electromagnetic gradient can be utilized to determine the range between the wellbores.

Claim (Index 35):
A method of determining distance and direction to a target wellbore, the method comprising:\n producing an electrical current with a current source disposed at a surface location; transmitting the electrical current into the target wellbore along an electrical conductor electrically coupled to the current source at the surface location; injecting the electrical current through a direct electrical connection established between the electrical conductor and a conductive body disposed in at least a portion of the target wellbore, wherein the conductive body includes an insulating section therein disposed uphole from the location of the direct electrical connection; and taking measurements of magnetic field data of the electromagnetic field generated by an electrical current in the target wellbore.
