A torque head for gripping tubular members, in at least some aspects, has a housing, grip mechanism secured within the housing, the grip mechanism for selectively gripping a tubular member, the grip mechanism including at least one jaw selectively movable toward and away from a portion of a tubular member within the housing, the at least one jaw having mounted thereon slip apparatus for engaging the portion of the tubular member, the slip apparatus including die apparatus movably mounted to the at least one jaw, the die apparatus movable with respect to the at least one jaw so that relative movement of the tubular with respect to the torque head is possible to the extent that the die apparatus is movable.

Top drive casing system

An apparatus for facilitating the connection of tubulars, said apparatus comprising a winch, at least one wire line, and a device for gripping the tubular, the arrangement being such that, in use, the winch can be used to winch said at least one wire and said device to position a tubular below said top drive.

Method and apparatus for connecting tubulars using a top drive

The present invention provides for an apparatus and methods to prevent an operator from inadvertently dropping a string (210) into a wellbore (180) during assembling and disassembling of tubulars. Additionally, the apparatus and methods can be used to for running in casing, running in wellbore components or for a drill string.

Apparatus and methods for tubular makeup interlock

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.

Pipe running tool

An apparatus for facilitating the connection of tubulars using a top drive, which apparatus comprises a body (2; 102) connectable to said top drive, said body (2; 102) comprising at least one gripping element (5; 105) radially displaceable by hydraulic or pneumatic fluid to drivingly engage said tubular (30; 110) to permit a screw connection between said tubular and a further tubular to be tightened to the required torque.

Apparatus for facilitating the connection of tubulars using a top drive

During casing running, risks of accidents with the stabber, the stabbing board and around well centre are still existing. In order to reduce the risks of accidents and to streamline the process a new Casing Running Tool is developed. The basic idea of this device is that the Top Drive is used as a torque wrench and that several functions are integrated. A flush mounted spider is used. Integrated in this device are fill up and circulating functions, the power tong function, the top stabbing function and the casing hoisting function. The risk for accidents will be significantly reduced. The driller's operation is simplified and the casing running time is reduced. The Casing Running Tool incorporates additional features, such as the possibility of pushing and rotating the casing string while circulating. The reduction of casing running time, personnel, and risk of accidents create value and HSE benefits. A first prototype is being developed. Design constraints that can be recognised at this stage of the development of the tool are mainly related to mechanized connection making. Both a theoretical and experimental approach are taken in order to define the design constraints. In the development of the Casing Running Tool a step by step approach is chosen. All subsystems are designed as add-on equipment. The Casing Running Tool paves the way to a complete automation of the drilling process.
