Abstract
A method for determining the direction and/or range from a drilling well to a target well may include positioning a magnetic source in the target well and a magnetic sensor in the drilling well. The method may include activating the magnetic source in the target well and moving one or both of the magnetic source and magnetic sensors until a location in which the magnetic sensor is not saturated is identified. The method may include determining the direction and/or range to the target well at that location.
