| Abstract | In one aspect a method of drilling a borehole is disclosed, wherein the method includes generating a primary electromagnetic field with a transmitter in a second borehole spaced from the first borehole, the primary electromagnetic filed causing electrical current in the conductive material of the first borehole, measuring a secondary electromagnetic field at a receiver in the second borehole, the electromagnetic field being responsive to the electrical current flowing in the conductive material in the first borehole, and determining a location of the first borehole using the measured secondary electromagnetic field. |
