I'm about to workover a well completed in the early 80's with an Otis model 'K' Hydraulic Tubing Hanger. Since the well was completed, almost all the well files have been lost (the asset has gone through three changes of ownership in the last 10 years), and I know nothing about this Model K Hydraulic Tubing Hanger, and even less about getting it out of the *@$*@** hole.
Does anyone have experience of retrieving these things? Is it a simple pull-to-retrieve? Any horror stories, lessons learned? Any idea of overpull needed (and any ideas on overpull now, after over 20 years in the hole!!)? I really do not want to have to start milling!
I've spoken to Halliburton, who are looking through their records, but without a part number sounded a bit dubious as they haven't made this piece of kit for some years, so I'm hoping that someone here can help!
