The feed members comprise screw surfaces by which the rods are supported in the magazine. The required feeding movement is produced by rotating the feed members about their rotation axis. In addition, the rod magazine comprises transfer means that allow the rods to be transferred from the magazine to a drilling line or bolting line, i.e. to a centre, and vice versa. The transfer means are provided with gripping means for gripping the rods.Type: ApplicationFiled: December 17, 2008Publication date: December 9, 2010Applicant: Sandvik Mining and Construction OyInventor: Juha Piipponen

Patent number: 7819609Abstract: A module is for use in drilling a borehole in a face of a mine passage using a drilling element and installing a bolt in the borehole once formed. The module may include a bolt holder for holding a plurality of bolts and a drilling element holder for holding a plurality of different drilling elements. A manipulator moves along an arcuate path between the bolt and drilling element holders to deliver the respective components to a drill head positioned along the arcuate path. The drill head may also slide relative to the mast in two different directions, and includes a drill guide for determining the location of the face to be worked. Related aspects of control of the module and methods are disclosed.Type: GrantFiled: July 5, 2007Date of Patent: October 26, 2010Assignee: J.H. Fletcher & Co.Inventors: Gregory E. Hinshaw, Henry E. Wilson, Craig M. Collins, William A. Kyslinger, William B. Schwab

Patent number: 7819207Abstract: A mobile oil, gas and geothermal well drilling rig provides for the rapid placement, assembly, disassembly, and repositioning of various rig components of the drilling rig. The drilling rig includes a support base and working floor which is trailerable and which can be rapidly erected to a working height at the well site. A drawworks trailer transports both the drawworks and the rig derrick. Hydraulic cylinders on the drawworks trailer are used to move the derrick from a horizontal, transport position to a vertical, working position while the weight of the derrick is off-loaded from the drawworks trailer to the base support structure.Type: GrantFiled: September 16, 2008Date of Patent: October 26, 2010Assignee: MD Cowan, Inc.Inventor: Mike D.

Patent number: 7814992Abstract: An apparatus for storing tubulars on a floating semi-submersible drilling or production vessel. The apparatus comprises a storage device for storing tubulars in a submerged position, essentially below a splash zone. The storage device is generally open to the surroundings so that the tubulars are externally exposed to surrounding water. It is also described an apparatus for transporting tubulars between a storage and a derrick on an offshore drilling and/or production platform having a platform deck. The apparatus is situated below the platform deck and is adapted for movement under the platform deck. A method for disassembling a pipe string is also described.Type: GrantFiled: December 21, 2005Date of Patent: October 19, 2010Assignee: Fred. Olsen Energy ASAInventor: Fred Olsen

Patent number: 7802620Abstract: A tool for dropping one or more balls and then one or more darts features a closable ball drop opening that works automatically after the ball release to minimize damage to the subsequently released dart. A retainer keeps the darts from coming back up above the dart launcher in the event of a pressure surge in the well. The dart launcher features a dedicated movable barrel for each dart that can be locked in a fully misaligned and fully aligned position with the casing or tubular. A handle is retained to the dart housing and can be manipulated to defeat the lock and rotate a given barrel. The darts may be inspected in their respective barrels before launch and the launch order is variable.Type: GrantFiled: July 19, 2005Date of Patent: September 28, 2010Assignee: Baker Hughes IncorporatedInventors: David A. Arce, John L. Baugh, Sidney K. Smith

Patent number: 7802636Abstract: A system and method for building and handling oilfield tubular stands while drilling operations are simultaneously and independently occurring with one drilling deck, one derrick, and one rotary system. An offline guided path horizontal to vertical arm lifts and moves in the same plane tubulars stored horizontally on the catwalk and positions the tubulars vertically directly into a preparation hole for assembling and disassembling tubular stands while online drilling operations are simultaneously being conducted. A stand arm lifts and lowers the tubulars into and out of the adjustable preparation hole, and transports the tubulars for storage to an auxiliary tubular racking station in the upper part of the derrick. A bridge racker crane moves tubular stands from the auxiliary tubular racking station to the top drive or another tubular racking station.Type: GrantFiled: February 23, 2007Date of Patent: September 28, 2010Assignees: Atwood Oceanics, Inc., Friede Goldman United, Ltd.Inventors: Mark Alan Childers, Brendan William Larkin, Harvey Mark Rich, Barry M.

Publication number: 20100230166Abstract: A derrickless system for servicing tubulars at a wellhead has a first tubular handling apparatus with a gripper positioned adjacent the wellhead where the gripper grips a surface of one of the tubulars, a second tubular handling apparatus with a gripper positioned adjacent the wellhead where the gripper grips a surface of another of the tubulars, and a slip assembly positioned in the wellhead. The slip assembly has a wedge bowl positioned at the wellhead that is suitable for receiving the tubular therein, and wedges positioned in the wedge bowl that are suitable for positioning between the wedge bowl and the tubular. Each of the grippers of the first and second tubular handling apparatus has a stab frame and three grippers attached to the stab frame.Type: ApplicationFiled: March 12, 2009Publication date: September 16, 2010Applicant: T&T ENGINEERING SERVICESInventors: Axel M.

Patent number: 7753138Abstract: A system for coupling a pipe segment to a pipe string is provided that includes a top drive assembly having an output shaft; and a pipe running tool coupled to the top drive assembly and rotatable by the output shaft of the top drive assembly. The pipe running tool includes an internal gripper for insertion within an internal diameter of the pipe segment and a tapered slip cone section, which slidably receives corresponding tapered surfaces of a plurality of slips, such that a vertical force on the slips causes the slips to move radially outwardly into gripping engagement with the internal diameter of the pipe segment, and wherein the vertical force applied to the slips is sufficient to allow the gripping engagement of the slips with the internal diameter of the pipe segment to transmit a torque from the top drive output shaft to the pipe segment.Type: GrantFiled: June 24, 2005Date of Patent: July 13, 2010Assignee: Varco I/P, Inc.Inventors: Daniel Juhasz, George Boyadjieff, Brian L.
