Condition for working coiled tubing through a pressurized stripper, where wellbore pressure applied against the cross-sectional area of the tube creates an upward acting force greater than the weight of the tubing in the wellbore.

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 stripper.

OBS

snubbing : A term used to describe the process of removing or installing pipe into a pressurized well bore, using specialized equipment including blowout preventers in a special arrangement.

OBS

In this condition, mechanical assistance is required to apply thrust to the tubing while injecting or to maintain control of the tubing when extracting. This condition is commonly called "light pipe operations."

CONT

En cas d'éruption en cours de forage, deux dispositifs de sécurité sont prévus. Les premiers correspondent aux fermetures de sécurité de Shaffer que l'on peut bloquer presque instantanément, soit manuellement, soit au moyen d'air comprimé. Ces fermetures ont des mâchoires semi-circulaires en caoutchouc qui peuvent s'ajuster étroitement autour du train des tiges, de la garniture du forage ou du tubage, de façon à obturer l'espace annulaire environnant.

OBS

mâchoire : Élément de fermeture et d'étanchéité d'un bloc obturateur de puits. Il existe trois types de mâchoires : la mâchoire pleine, la mâchoire de fermeture sur tige et les mâchoires-cisailles que l'on peut monter dans les obturateurs empilés verticalement à l'entrée du puits.

The total footage of casing run in a well.

Casing is manufactured in lengths of about 30 ft, each length or joint being joined to another as casing is run in a well. The entire length of all the joints of casing is called the casing string.

CONT

The upper drill pipe is constantly moving vertically through the marine riser, the blowout preventers, the wellhead, and the casing strings.

CONT

If casing is needed lower down than the bottom of the previous casing, a new string of lining pipe must be extended into the well from the surface. Each additional casing string reduces the internal diameter of the well.

DEF

In drilling, to prevent the threatened blowout of a well by suitable preventive measures(e. g., to shut in the well with the blowout preventers, circulate the kick out, and increase the weight of the drilling mud). In production, to stop a well from producing oil and gas so that reconditioning of the well may proceed.

OBS

In both cases it is usually accomplished by the injection of a dense fluid into the well.

Surface chokes are part of the Christmas tree and contain a choke nipple, or bean, with a small-diameter bore that serves to restrict the flow.

It has been suggested ... that since the thinnest layer of sand to act successfully as an erosion pumping filter was 25 mm, and the slurry penetrated /3mm in this case, then a geotextile with a thickness of 10 mm or more might successfully replace the sand blanket layer. The fact that the most successful sand blanket have voids ranging from 5 to 30 [micrometers] seems to suggest that the geotextile’s voids should be of a similar magnitude. Erosion pumping filters, using a geotextile in conjunction with a sand blanket, are much more effective than geotextiles alone.
