Generally the apparatus includes pipehandling equipment arranged to interact with an off-floor rack, a preparation opening, a borehole, and a storage area, such that tubulars can be loaded onto the drill floor, prepared at the preparation opening, loaded onto or off of the storage rack, and connected to a drill string while drilling is simultaneously conducted at borehole. In one embodiment, the system includes at least two pipehandling devices for communicating pipe between a storage area off the drill floor, a storage area on the drill floor, at least one preparation opening, and a drill opening.Type: GrantFiled: December 12, 2003Date of Patent: December 20, 2005Assignee: Varco I/P, Inc.Inventor: Joe Berry

Patent number: 6938709Abstract: A pipe running tool for use in an oil drilling system and the like comprises a lower drive shaft adapted to engage a drive shaft of a top drive assembly for rotation therewith. The pipe running tool further includes a lower pipe engagement assembly which is driven to rotate by the lower drive shaft, and is designed to releasably engage a pipe segment in such a manner to substantially prevent relative rotation between the two. Thus, when the lower pipe engagement assembly is actuated to securely hold a pipe segment, the top drive assembly may be actuated to rotate the top drive output shaft, which causes the lower drive shaft and lower pipe engagement assembly to rotate, which in turn rotates the pipe segment.Type: GrantFiled: July 3, 2002Date of Patent: September 6, 2005Assignee: Varco International, Inc.Inventors: Daniel Juhasz, George Boyadjieff, Brian L. Eidem, Hans van Rijzingen, Herman Kamphorst, Dieter Boettger, Guus van Wechem

Patent number: 6935440Abstract: A service rig, comprising a mast, a torque carrier suspended from the mast; and a brace having a torque carrier end connected to the torque carrier for conveying torque from the torque carrier into the brace and an anchored end with a fastener for attaching the brace to a substructure at a well or the back of the service rig. When the service rig is in operation over a well and has a substructure, the anchored end of the brace is horizontally offset from a point on the substructure directly below the torque carrier end of the brace. The anchored end of the brace, when in operative position, is oriented parallel to an extension of the torque carrier. The anchored end of the brace preferably constitutes an offset extension of the torque carrier. If a substructure is not available, the torque carrier extension may be anchored to the back of the service or workover rig.Type: GrantFiled: August 1, 2003Date of Patent: August 30, 2005Inventors: Allan R. Nelson, Vladimir W. Lacika

Patent number: 6920926Abstract: A well casing system is disclosed for the handling and make-up of casing on a drilling rig in conjunction with a top drive is disclosed. The system comprises a top drive, a casing make-up assembly, links, link tilts, and transfer and lifting elevators. The operator can remotely manipulate the elevators to pick up and position a joint of casing above the casing already secured in the drilling hole. The operator can then engage the gripper head and use the rotational capability of the top drive to remotely couple the two joints of casing together.Type: GrantFiled: January 16, 2004Date of Patent: July 26, 2005Assignee: Canrig Drilling Technology, Ltd.Inventors: Lemuel T. York, Allan S. Richardson, Beat Kuttel

Patent number: 6913096Abstract: A top drive well drilling apparatus includes a body with means for suspending the body from a drilling rig. A motor is secured to the body. The motor has a central passage defining a rotational axis. The central passage is adapted to receive a tubular drive shaft. A pipe gripping assembly is provided which underlies and is in axial alignment with the central passage. The pipe gripping assembly rotates independent of the motor for purposes of orientation.Type: GrantFiled: March 28, 2003Date of Patent: July 5, 2005Inventors: Shawn James Nielsen, Sinisa Dobrijevic

Patent number: 6845825Abstract: A control system for a drilling machine is disclosed. The drilling machine includes a rod driver for driving a string of rods into the ground, and for removing the string of rods from the ground. The drilling machine also includes a magazine for storing rods near the rod driver. A rod transfer mechanism moves rods between the magazine and the rod driver. Vices are used to make and break joints between the rods of the drill string. The control system includes joysticks equipped with switches for controlling operational sequences of the vices and the rod transfer mechanism.Type: GrantFiled: January 22, 2002Date of Patent: January 25, 2005Assignee: Vermeer Manufacturing CompanyInventors: Brian J. Bischel, Mark Van Howelingen, Mark R. Stelter, Trail Price, Peter C. Rozendaal

Publication number: 20040256156Abstract: A drill gripping device is shown with an inexpensive and compact design. In one embodiment, an inexpensive and more compact design is possible through the use of a single actuator with a single gripping portion of a drill gripping device. Embodiments of drill gripping devices shown are further reduced in price and size due to a force amplification device such as a camming arm. Alternatively, an increased gripping force is possible using an existing size actuator. A drill gripping device is shown with increased precision in gripping. A pair of gripping jaws are synchronized to improve jaw centering capabilities.Type: ApplicationFiled: January 9, 2004Publication date: December 23, 2004Inventor: Michael Tjader

Patent number: 6832658Abstract: A torque track in conjunction with parallelogram links and a hydraulic cylinder is used for multiple purposes in a drilling rig top drive system. The torque track is rotationally mounted within the mast between the crown and the rig floor and pivotally mounted by the parallel linkages to the sides of a power swivel. The hydraulic cylinder is mounted to an arm at the lower end of the track and it's other end is connected to the fixed rig structure. When the power swivel is supplying torque during drilling, the linkage transmits the torque to the track which is restrained from rotating by the hydraulic cylinder. The torque is thereby transmitted via the hydraulic cylinder to the fixed rig structure rather than the mast. The hydraulic cylinder can also be used as a load cell to allow torque measurement as well as to pivot the power swivel when needed for pipe handling purposes. The arrangement thus provides triple top drive functionality.Type: GrantFiled: October 11, 2002Date of Patent: December 21, 2004Inventor: Larry G. Keast

Patent number: 6821071Abstract: An automated pipe racking apparatus for a drilling rig having an elevator suspended over a well bore. An arm support member is rotatable about an axis parallel to the well bore. A gripper arm extends from the arm support member along an axis normal to the axis of rotation of the arm support member. A gripper head assembly extends from the gripper arm, the gripper head assembly having a pair of opposed, arcuate gripper fingers, each said finger rotatable by a motor.Type: GrantFiled: September 25, 2002Date of Patent: November 23, 2004Assignee: Woolslayer Companies, Inc.Inventors: Joseph R.

Publication number: 20040216924Abstract: A method and apparatus for holding and turning a tubular and string of tubulars, such as casing, for make-up and drilling with the tubulars are disclosed. The apparatus generally includes a spear and a clamping head, both of which are mounted to a top drive. The spear and the clamping head can be engaged to transmit torque therebetween from the top drive. In addition, an aspect of the invention provides variable height wickers positioned on slips to enable use of the slips with variable inner diameter (ID) and weight casing without deformation or rupture of the casing. Still further, a casing collar is also provided to provide reinforcement to the casing in the area of slip contact with the casing ID.Type: ApplicationFiled: March 5, 2004Publication date: November 4, 2004Inventors: Bernd-Georg Pietras, Thomas F. Bailey, Adrian Vuyk,, Carl J. Wilson
