Abstract
A method and apparatus for injecting coiled tubing into a submerged well. The end of a coiled tubing is latched in a tubing injector and the tubing and injector are lowered through a body of water together. The injector is latched to the well and the injector moves the coiled tubing through the well. The injector weight is exerted on the tubing during movement through the body of water. The injector may be contained in a bell type or complete enclosure and fluid in the enclosure is maintained at approximately the external pressure. The injector may be connected to a shear, a stuffing box, and a tool receiver.
