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: 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: 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.

Abstract: To search for an avalanche victim wearing a radio transmitter continually transmitting at a standardized frequency, the method according to the invention comprises: a victim detection phase during which a rescue worker wearing a receiver methodically covers the zone snowed in by the avalanche during which time the receiver detects the moments when the amplitude of the signal received is greater than a lower threshold, a phase of directional search for the victim during which the rescue worker rotates with the receiver while the latter detects the moments when the amplitude of the signal received is at the maximum, and signals these moments to the rescue worker who is then pointed towards the victim, a phase during which the rescue worker advances towards the victim, during which the receiver checks that the amplitude of the signal remains at the maximum, and detects the moments when the amplitude of the signal received exceeds an upper threshold.
