Abstract
A method for drilling a subterranean wellbore includes rotating a bottom hole assembly (BHA) in the subterranean wellbore to drill the wellbore, the BHA including a drill collar, a drill bit, and a triaxial accelerometer set and a triaxial magnetometer set in or coupled to the drill collar. The triaxial accelerometer set and the triaxial magnetometer set make a plurality of sets of synchronized accelerometer measurements and magnetometer measurements while drilling. These synchronized measurements are processed to compute an interference magnetic field which is in turn processed to compute at least one of a distance or a direction to a magnetic target located external to the wellbore.
