More Information
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 appratus (42). A hydraulic workover jack (11) is combined with a multifunction injector head and a standpipe for fluid circulation. The invention may also include a rotary table (15) for rotating pipe and/or rotating power swivel (16) to allow fluid circulation during pipe rotation. Also included are a gin pole (8), a winching system for jointed pipe, and a traveling head with traveling slips (12) and stationary slips (13) to allow pipe movement in the well. Hydraulic systems allow insertion and extraction of tools in a work string. The apparatus includes spoodable drill pipe (43) including a connector, multi-section reel with core, connection to reel for fluid circulation, reel drive mechanism and a pipe pulling capability.
