Abstract: A tractor comprises a tractor module (10) coupled at opposite ends to a cleaning or inspection module (11) and a power generation module (12), the three modules being arranged in line within a pipeline (14) such that traction elements (15) on the tractor module (10) engage the wall of the pipeline (14). In operation within a pipeline along which fluid is flowing in the direction (16), drive is imparted to the power generation module (12) by the fluid flow, and the tractor module (10) is driven in the direction (17) by the power generation module (12) by way of a drive shaft (21) and appropriate step-down gearing (not shown). A speed governor is used to control the rotational speed of the drive shaft (21) such that the tractor speed is not directly related to the speed of the fluid flow, and is preferably substantially independent of the speed of the fluid flow. A tractor travelling at a constant and/or controlled speed is found to achieve better cleaining, or to enable more efficient inspections, than a tractor which is propelled along the pipeline at the rate of fluid flow in the pipeline.

Abstract: The present invention provides an apparatus and method for expanding a first tubular (120) against a second tubular (110). In one aspect, an expander tool (300) includes a mandrel coupled to a spline assembly (330, 430) such that an annular space is formed between the same. Seals are placed between the mandrel and the spline assembly to retain a fluid in the annular space. In operation, the mandrel (310) is rotated, which, in turn, rotates the expander members (350). Rotation of the mandrel also causes the spline assembly (430, 330) to extend axially, thereby pulling a first seal (360) closer to a second seal (355). As a result, the pressure in the annular space (340) rises due to the compression of the fluid in the annular space. The rise in pressure extends the expander members into contact with the first tubular and expands the first tubular against the second tubular.

Abstract: A rapid locking tubular coupling device is provided connecting two abutting tubular elements (11, 12) (referred to hereinafter as pipes) which consists of four components as follows: 1) first coupling shell element (13), 2) second coupling shell element (14), 3) sliding sleeve (15), 4) setscrews (16) (or interference pins). Each pipe (11, 12) has two or three circumferential grooves (19) cut into the end of the pipe and extending into the pipe wall to a depth of 1/3 of the pipe wall thickness. Two shells (13, 14) are formed as semi-circular pieces, which have 4 or 6 protruding ridges (20) on their inner surfaces. These protruding ridges match the machined grooves (19) in the tubes (11, 12) such that when the two tubes are joined together, the shell elements (13, 14) will interface with grooves (19) on both pipes (11, 12). The outer surfaces of the shell elements (13, 14) are cut with a slight taper such that the diameter increases as you move from the bottom pipe (12) to the top pipe (11), and a sliding sleeve (15) with an internal taper matching the external taper of the first and second shell elements (13, 14) clamps the shell elements (13, 14) to the pipes (11, 12) and is held in place by setcrews (16).

Abstract: A ball dropping assembly (350) for dropping one or more objects, such as spherical balls, (5,5',5") into a wellbore (7). The assembly comprises a seat (330) for retaining a ball before it is released. The assembly may also comprise a ball feeding channel (380) for feeding additional balls onto the seat. A ball retaining lever (40) is provided to selectively receive and retain balls onto the seat (330), and then to release the balls individually into the wellbore (6). In one embodiment, the assembly is attached to a side bore (4) in fluid communication with a main bore in a cementing head (105). The ball-retaining lever (40) rotates into the bore (6) when releasing a ball (5'). When a plug (8) is released into the bore from a cementing head (105), the plug (8) will trip the lever (40), causing the ball-retaining lever to rotate back towards the ball-retained position. Thus, the ball dropping assembly also serves as a plug release indicator.

Abstract: The present invention generally relates to disconnects for use in a wellbore to separate a tubular string from a stuck wellbore component. In one aspect, the invention includes a disconnect (100) with a first portion (101) and a second portion (109) and a lock nut (146) preventing the separation of the two portions. When a predetermined fluid force is applied to a piston in the disconnect, a tensile sleeve (122) fails and the first and second portions of the disconnect separate, thereby leaving a portion of the disconnect in the wellbore with the stuck component. In one embodiment, the tensile sleeve's failure permits an annular piston (130) to dislodge a wedge sleeve (150) from the lock nut, thereby permitting separation of the first and second portion of the disconnect.
