Patent number: 11767713Abstract: A top drive for well operations having a gearbox, a traction motor connected to the gearbox so that a motor shaft of the traction motor extends into the gearbox, a quill extending into the gearbox, a gear train positioned within the gearbox and mechanically connected between the traction motor shaft and the quill, and a connector positioned in the gear train, wherein in a coupled configuration the connector communicates torque through the gear train, and wherein in a decoupled configuration the connector does not communicate torque through the gear train. A method for operating a top drive by applying a first torque to a quill with two traction motors, disconnecting one of the traction motors from the quill, and applying a second torque less than the first torque to the quill with the non-disconnected traction motor.Type: GrantFiled: June 23, 2022Date of Patent: September 26, 2023Assignee: Schlumberger Technology CorporationInventors: Brynjulv Aas, Jonathan David Deagle, Peter William Cave

Publication number: 20200048969Abstract: Embodiments of a locking ring assembly of this disclosure may be used to prevent unwanted rotation of a drill stem sub or tubular when another sub or tubular of the drill stem is subjected to a disconnect or reverse torque force. The locking ring assembly may include an upper and a lower rings having two halves connected on one end by a hinge and on another end by a fastener. Each locking ring half may include convexities located along an inner wall surface. When locking ring is in a closed position the convexities at least partly penetrate an opposing surface of the drill stem sub or tubular, thereby maintaining locking force by shear force rather than friction force. One or more keys may be installed between the upper and lower rings to prevent undesired or excessive torque experienced by one ring being transmitted to the other.Type: ApplicationFiled: August 9, 2018Publication date: February 13, 2020Inventors: Brynjulv Aas, Magnus Berg

Patent number: 7887098Abstract: A locking device for locking a threaded pipe connection where two threaded connection units are screwed together. The locking device includes two locking rings which engage each other with corresponding teeth and notches on their first sides. Each of the two rings has a different number of teeth and notches on their second side. The two second sides, which face the connection units, are formed to engage a corresponding number of notches and teeth formed on the shoulder of the connection unit's opposite side, after the rings have been spread apart in an axial direction, while maintaining the engagement between the first and the second ring.Type: GrantFiled: September 17, 2004Date of Patent: February 15, 2011Assignee: National Oil Well Norway ASInventor: Brynjulv Aas
