Abstract: A mobile service rig with an integrated pipe handling assembly is provided. The rig includes an elongate frame, an attached elongate mast, and an attached a pipe handling assembly. The mast base is pivotally attached to the frame for moving the mast between horizontal and vertical orientations. The pipe handling assembly includes a pipe trough and a trough lifting arm pivotally attached to frame and pipe trough to move a pipe between a horizontal orientation and a vertical orientation collinear with the mast in the vertical orientation. The pipe handling assembly may also include a pair of pipe racks pivotally attached to the frame to extend transversely away from the frame.

Abstract: A bed truck having multiple axles has a hydraulic suspension including multiple hydraulic cylinders for each axle, a ride height sensor associated with each hydraulic cylinder, a high pressure hydraulic circuit connecting each of the cylinders and accumulators to a hydraulic pressure source, a low pressure hydraulic circuit connecting each of the cylinders to a fluid tank, and a plurality of valves operable to isolate operation of any one hydraulic cylinder from some or all of the other hydraulic cylinders. A control system is operable to control each of the hydraulic cylinders, either independently of all the other hydraulic cylinders, or in concert with one or more other hydraulic cylinders, such control including locking any one or more of the hydraulic cylinders at a minimum ride height position.

Abstract: A system and method for monitoring and displaying operating conditions of a winch mechanism.

Abstract: A drill pipe assembly includes a tubular body and a roller assembly for reducing friction between the drill pipe and the inner wall of a wellbore. The tubular body includes a substantially cylindrical body outer surface defining roller pockets. Alternatively, the drill pipe assembly may have a sleeve that fits concentrically and rotatably around the tubular body, with the sleeve outer surface defining the roller pockets. Each roller pocket has a roller assembly that includes an axle having opposed ends retained by the tubular body or the sleeve. A roller is retained by and rotates on each axle, partially disposed in the roller pocket and partially projecting outwardly from the outer surface.

Abstract: The present invention is directed to a mobile coiled tubing unit that has a moveable coiled tubing reel and mast. The apparatus itself can be moved laterally using retractable jacks and hydraulic cylinders. The mast is retractable into a mast sleeve. The movable nature of the elements of the apparatus allow for easier alignment with the well head and balanced transportation. The reel can also be raised to increase clearance to facilitate transportation over rough or uneven terrain.
