Abstract
Certain embodiments described herein provide an estimate of the magnetic interference incident upon a drilling system using multiple magneticclaim sensors within a downhole portion of the drilling system in a first wellbore. Certain embodiments utilize the magnetic measurements to determine an axial interference resulting from one or more magnetic portions of the downhole portion and to provide an estimate of a relative location of a second wellbore spaced from the first wellbore.
