Abstract: A connector (301) is provided for coupling a tubular member (303) to a selected apparatus. The tubular member (303) has inner and outer surfaces (305, 307) and terminates at an end (311) with the inner surface (305) at least in-part defining a central bore (309). A central body (313) is provided with first and second ends. A linkage member (315) is disposed at the first end of the central body (313) for connecting the central body (313) to a selected apparatus. A tubing coupler (317) is disposed at the second end of the central body, and is operable in an insertion mode of operation in a radially-reduced position for insertion into the central bore (309) of the tubular member (303) and a coupling mode of operation in a radially-expanded position for grippingly and sealingly engaging the inner surface (305) of the tubular member (303).

Abstract: A flush self-locking threaded connection partially in a non-locking engagement comprises a first and a second tubular component provided respectively with male and female threaded zone at their respective ends. First portions of the male and female threaded zones with varying thread width and root cooperate along a self-locking tightening arrangement. A locking region within the threaded connection is located in the middle of non- locking regions, and radially centered to the pipe body API tolerances in order to withstand high torque and seal performances.

Abstract: An apparatus for transferring torque comprising a pipe handling assembly configured to use fluid pressure to provide torque forces to set or release slips from a pipe. Set down force or other frictional measures on a pipe collar are not required. A method to create reactive torque force comprising a series of gears interconnected with each other through a clutch that can be engaged and disengaged. A link may be provided to a top drive rail via a gripperbox which provides reactive force to stop rotation of a power screw female (threaded nut) to facilitate threading action to set or release slips on pipe. Reactive force may be created using a plurality of axial pistons attached to a moveable half of a hirth coupling. Other friction-creating members (such as, for example, a brake pad material or similar material) may be used to create frictional forcesbetween two surfaces.

Abstract: An alignment sub (100) includes a first sub body part (101) rotatably coupled to a second sub body part (118). The first sub body part and second sub body part are respectively non-rota tably coupled to a first wellbore tool and a second wellbore tool. A lock screw (129) switchable between an unlocked state and a locked state may fix an angular position of the first sub body part (101) relative to an angular position of the second sub body part (118) when the lock screw is in the locked state.

Abstract: A tubular string having a box end and pin end coupled to one another with a threaded attachment and a coupling assembly. The coupling assembly includes an annular outer thrust ring having an axial end abutting a shoulder on a terminal end of the box end. Included with the coupling assembly is an inner thrust ring, which is also annular, and which has an end that axially abuts a shoulder formed along an outer surface of the pin end. An alternate type of the inner thrust ring is made up of two separate semi-circular members that circumscribe the pin end when positioned in the recess so their arcuate ends adjoin. The inner thrust ring inserts into the outer thrust ring, and has a radial surface on its outer circumference that lands on a shoulder formed along an inner circumference of the outer thrust ring.

The drive member having a housing with a bore therethrough and a window formed substantially laterally through the housing. An adapter of the tool is configured to be inserted through the window of the housing. In another embodiment, a method for coupling a top drive to a tool includes moving the tool adjacent to the top drive, the tool including an adapter and the top drive including a housing having a window formed therethrough. The method also includes aligning the adapter with the window and inserting the adapter substantially laterally into the window of the housing, thereby longitudinally and torsionally coupling the top drive and the tool.
