The running or pulling of tubulars from a well under high pressure with a snubbing unit and the well shut in. Conventional snubbing can be accomplished with mechanical snubbers, a hydraulic snubbing unit, or a coiled tubing unit.
Snubbing is in contrast to stripping in which well pressures are lower and the pipe can be run under into its own weight. Snubbing is required if the pressure-induced forces exceed the string weight. Snubbing will be required initially to get the pipe in the well.
