Abstract
A first rig comprises a collapsible mast having one open side for receiving conventional sectional tubing and a second open side for receiving the injector of a second coiled tubing injection rig. Accordingly, lengths of sectional tubulars can be bandied or drawn up the first open side from the first rig; and coiled tubing can be introduced from the second side. A combination of strong and dual draw works, the dual open side mast and rotary table of a conventional rig minimize serial handling and enable making up both sectional tubing for assembling BHA's, drilling surface hole and making up to non-rotating coiled tubing from the coiled tubing injector.
