Patent number: 11459828Abstract: An apparatus for drilling a directional wellbore is disclosed that in one non-limiting embodiment includes a drive for rotating a drill bit, a deflection device that enables a lower section of the drilling assembly to tilt about a member of the deflection device within a selected plane when the drilling assembly is substantially rotationally stationary to allow drilling of a curved section of the wellbore when the drill bit is rotated by the drive and wherein the tilt is reduced when the drilling assembly is rotated to allow drilling of a straighter section of the wellbore, and a tilt sensor that provides measurements relating to tilt of the lower section. A controller determines a parameter of interest relating to the tilt for controlling drilling of the directional wellbore.Type: GrantFiled: September 23, 2016Date of Patent: October 4, 2022Assignee: BAKER HUGHES, LLCInventors: Volker Peters, Andreas Peter, Christian Fulda, Heiko Eggers, Harald Grimmer
