n: 1. a device that mechanically or hydraulically forces pipe or tools into the well against pressure. 2. a device within some hooks that acts as a shock absorber in eliminating the bouncing action of pipe as it is picked up.

n: A suit of equipment be controled by hydraulic pressure,which can tripping in at definite pressure.

Snubbing usually requires an array of wireline blocks and wire rope that forces the pipe or tools into the well through a stripper head or blowout preventer until the weight of the string is sufficient to overcome the lifting effect of the well pressure on the pipe in the preventer. In workover opera- tions, snubbing is usually accomplished by using hydraulic power to force the pipe through the stripping head or blowout preventer. 2. to tie up short with a line.

n: the process of lowering pipe into the wellbore when the well is shut in on a kick and when the pipes weight is not sufficient to overcome the force of well pressure.

forcing pipe into a well against the effects of wellhead pressure.

a job where the well is workover without killing the well. Usually accomplished by multiple barriers that seal on the tubulars.

a set of pipe seal and blind rams used in the snubbing operation.

n: either a stand-alone device or a rig-assist device that is used to force pipe into the well when the well is shut in on a kick. When the pipes weight is not sufficient to overcome the upward force of well pressure, a snubbing unit must be used. Compare stripping in.

n: a tank safety device that seals the vapor vent manually and prevents vapor from escaping into a fire, thus snuffing out the flame.

abbr: show of oil;used in drilling reports.

oil saturation.
