ABSTRACT:
A method for introducing reeled tubing into oil and gas wells, in which a relatively stiff pipe segment is connected to the leading end of the reeled tubing before the reeled tubing is introduced into the well. The reeled tubing, with the pipe segment attached to its leading end, is unwound from its reel and the pipe segment reduces damage to the wall of the well and jamming of the reeled tubing in the well as the tubing passes through the well.
