Abstract:
Methods for drilling wells using magnetic ranging while drilling to position the wells with respect to one another are provided. In accordance with one embodiment, a method of drilling a well includes leaving a drill string in position within a primary well, and drilling a secondary well using the drill string as a target for magnetic ranging while drilling such that the secondary well is positioned with a specified orientation relative to the drill string.
