What Does
Pipe Sticking Mean?
Pipe sticking is when a drill pipe is stuck in a borehole and cannot be recovered from the bore without damage to the drill pipe. It can occur because of a variety of reasons which are loosely classified as either differential pressure issues or mechanical issues.
Pipe sticking causes time-consuming and expensive disruption in drilling operations. There are warning signs which, if observed, tend to forewarn of pipe sticking. These indicators generally require immediate action from the drill crew to prevent a stuck pipe.
