Abstract
A system and method for drilling a second well with respect to a first well is disclosed. A first drill string having a known magnetic signature is disposed at a first depth in the first well. A second drill string is used to drill the second well. The second drill string includes a magnetometer that obtains a magnetic measurement of the first drill string during drilling of the second well. A processor uses the obtained magnetic measurement and the magnetic signature of the first drill string to steer the second drill string to drill the second well.
