Abstract: A coiled tubing injector system which includes transport trailer components for separate transfer to and from a drilling site. Each component is taken to the site with its own transport tractor, a first component including a coil storage reel and a second component including a tubing injector carried on a mast which is raised from a horizontal transport position, through a stabbing and unstabbing position to a raised working position. When the components are arranged together in an end-to-end with the mast in a stabbing position, a tube gripping member is positioned between the storage reel and tubing injector for controlling the handling of a free end of the stored tubing for stabbing and unstabbing of the tubing injector.

Abstract: A drilling rig for use in both coiled tubing injection and rigid threaded pipe operations, and consisting of a number of separably transportable modules which are assembled on site for carrying out the operations. Included in the modules are a substructure component, a mast component and an injector component. In setting up for operation, the mast component is combined on site with the substructure component which supports the assembled rig over the borehole. The mast component in location provides a loading area to support the injector component in a position for ready loading of an injector included in the injector component into the mast when required for a coiled tubing operation.
