Abstract
A drilling assembly, drilling system and method is provided. The drilling system includes a drilling rig with a drill string deployable therefrom and drivable thereby. The drill string has a bottom hole assembly with a drill bit at a lower end thereof advanceable into a subterranean formation to form a wellbore. The drilling assembly includes at least one mandrel operatively connectable to the drill string, at least one sleeve positionable about the mandrel (the sleeve having an offset stabilizer on an outer surface thereof selectively positionable in contact with a wall of the wellbore), and an orienter with a receptacle on an interior of the sleeve and a socket on an exterior of the mandrel. The socket is interlockingly engageable with the receptacle whereby the sleeve is orientable about the drill string. The one mandrel and the sleeve have a mass offset from the drill string whereby rotation of the drill string is affected during drilling.
