Abstract: A system for positioning a trailer mounted coiled tubing tensioner either in a first stowed position on the deck of a transport trailer or in a second position resting on an elevated rig floor of a drilling rig is described. The system for selectably elevating a coiled tubing tensioner from its first stowed position to its second position on the rig floor of a drilling rig includes the cooperative operation of the coiled tubing tensioner and its frame, multiple pivotable swing arms attached to the trailer at one end and the tensioner frame at the other end, an elevatable mast, a crown block, a drawworks winch, a top drive, a pair of tensioner lifting winches and multiple lifting lines deployed from the mast and reeved through sheaves mounted on the tensioner frame and the top drive.

Abstract: A threaded tubing end assembly having a tubing with a transverse first end, a tubing through bore, and a longitudinal weld seam; a threaded adapter having an adapter through bore, and an adapter body having a threaded first end having a male thread and an opposed second end with an external transverse shoulder surrounding a reduced diameter elongated shank with an external longitudinal slot; a circumferential weld; and a longitudinal weld.

Abstract: A simple flexible coiled tubing connector couples the ends of two separate sections of tubing so that mutual axial tensile forces can be transferred between the two sections. The tubing connector is intended for use with tubing which may be coiled on a storage reel and freely run through a coiled tubing straightener or tensioning device. The tubing connector is not required to contain pressure, transfer compressive axial loads, torsion, or loads transverse to the axes of the tubes.

Abstract: A simple mechanical height adjustment device adjusts the ground clearance of a trailer. The trailer, having the height adjustment device can selectably and reversibly increase its ground clearance. The trailer, having an adjustable ground clearance, can minimize its load height when operating on improved roads in order to meet local and state height regulation, but can increase its ground clearance on uneven roads.

Abstract: A mobile coiled tubing rig for the drilling and workover of wells is designed to have a control room for the coiled tubing rig positioned within a tank at the forward end of the rig during transport. The control room, stored in the empty tank during transit, is selectably elevated out of the tank to its working position during rig operation. When the control room is elevated, the operator or operators of the coiled tubing rig can see the coiled tubing storage wheel and the coiled tubing injector.

Abstract: A selectably elevatable coiled tubing injector is described that is suitable for a mobile self-contained unitized coil tubing rig for the drilling and workover of petroleum wells. The selectably elevatable coiled tubing injector includes a mechanism for positioning a trailer mounted coiled tubing injector either in a first stowed position on the deck of the transport trailer or in a second position resting on an elevated rig floor of a drilling rig. Furthermore, the selectably elevatable coiled tubing injector includes a further mechanism for selectably elevating the injector above its second position on the rig floor while clamping the tubing in order to provide additional tension on the tubing string or to raise the tubing deployed within a well.

Abstract: A device for applying tension to a string of coiled tubing for the purpose of its insertion into or withdrawal from a wellbore. Specifically, the device is used with a wheel-type tensioner, which contacts and supports the tubing over an arc length of less than 180°. The device enhances the tractive ability of the tensioner by applying forces normal to the tubing to press it into more intimate contact with the surface of the wheel, thereby increasing the normal force and attendant frictional force between the tubing and the wheel.

Abstract: The present invention relates to pins that may be selectably operated to engage and disengage socket bores in the assembly and disassembly of large structures, such as floating offshore platforms for deepwater applications. The pin connections can be engaged or disengaged robotically or under direct operator control. The construction and installation of structures utilizing the pin connections will typically use multiple sets of selectably operable pins to connect, support and stabilize the structural components of the structure.
