ThinJackGAP™
Real-Time Gap Data
Preventing Flange Jamming
In well interventions, the upward pull from a drill string and draw works is intended to separate flanges. However, once a flange tilts and jams, this powerful technique can inadvertently become a flange jamming system.
This is particularly relevant in scenarios where an old Christmas Tree, tubing, or casing spool is being replaced on a well conductor that is no longer vertical after 30 years. The vertical upward pull, combined with even a slight angle difference, significantly increases the likelihood of flange jamming.
Our ThinJackGAP™ solution enables real-time gap monitoring, ensuring the flange is removed vertically and preventing tilting and jamming during well interventions.
