  • Patent number: 11047180
    Abstract: A hole cleaning joint for a drill string is deployed into a wellbore penetrating a subterranean formation. The hole cleaning joint includes a tubular body connectable to the drill string and a hole cleaning section positionable about the tubular body. The hole cleaning section has an outer surface engageable with a wall of the well bore. The outer surface has spiral grooves extending therein defining blades therebetween, and an uphole end and a downhole end with a spiral cavity therebetween. The spiral cavity has a width that decreases towards the uphole end of the spiral cavity to define a tapered flow channel to receive cuttings therethrough whereby uphole movement of cuttings is facilitated during drilling.

  • Publication number: 20140008127
    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.
