Summary: | Method and apparatus for drilling, completion, well workovers and well control, combining an integrated lifting unit and a coiled tubing unit, the method and apparatus permit running jointed pipe and coil tubing in combination, and standing multiple joints of pipe near the unit. The invention combines a hydraulic pipe hoisting system, pipe handling systems and pipe racking containment apparatus. A hydraulic workover jack is combined with a multifunction injector head and a standpipe for fluid circulation. The invention may also include a rotary table for rotating pipe and/or a rotating power swivel to allow fluid circulation during pipe rotation. Also included are a gin pole, a winching system for jointed pipe, and a traveling head with traveling slips and stationary slips to allow pipe movement in the well. Hydraulic systems allow insertion and extraction of tools in a work string. The apparatus includes spoolable drill pipe including a connector, multi-section reel with core, connection to reel for fluid circulation, reel drive mechanism and a pipe pulling capability. |
