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

Patent number: 10738600Abstract: A method for drilling a borehole penetrating an earth formation includes: drilling a first section of the borehole; notching a wall of the borehole in one or more selected locations with a selected type of notch using a notcher for defined local weakening of the formation; performing a local induced break-out test and/or local fracturing operation on an annulus section of the first section of the borehole between the drill string and a wall of the borehole using a test tool comprising a packer to provide formation stress-state data. The one or more locations is based on the formation stress-state data. The method further includes deriving stress-state of the formation and a fracturing parameter of the formation using the formation stress-state data and drilling a second section of the borehole using the derived stress-state and the fracturing parameter.Type: GrantFiled: May 19, 2017Date of Patent: August 11, 2020Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Joerg Lehr, Harald Grimmer, Stefan Wessling
