20130121801 | System for repositioning a coiled tubing tensioner - 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. | 05-16-2013 |
20130076025 | Threaded end connector attachment for an end of a tube - A simple threaded end connector is easily attached to the end of a tube. One embodiment of the threaded end connector attaches to the end of a coiled tubing string so to allow the coiled tubing string to easily connect to a variety of threaded downhole tools | 03-28-2013 |
20130038051 | Tubing connector and method for coupling two coiled tubing strings - 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. | 02-14-2013 |
20100201101 | Trailer with adjustable ground clearance - 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. | 08-12-2010 |
20100200214 | Selectably elevatable coiled tubing rig control housed within a water tank - 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. | 08-12-2010 |
