flowing tubing head pressure.

n: a specially fabricated length of casing or tubing usually placed temporarily above a valve on top of the casing- head or tubing head. It is used to run swabbing or perforating tools into a producing well and provides a method for sealing off pressure and thus should be rated for highest anticipated pressure.

n: A long, high-pressure pipe fitted to the top of a wellhead or Christmas tree so that tools may be put into a high-pressure well. The top of the lubricator assembly includes a high-pressure grease-injection section and sealing elements. The lubricator is i

a pressurized shell, mounted above the BOP or master valve, which houses the tool string when entering a live well.

n: an arrangement of slips and packing rings used to suspend tubing from a tubing head.

n: A device attached to the topmost tubing joint in the wellhead to support the tubing string. The tubing hanger typically is located in the tubing head, with both components incorporating a sealing system to ensure that the tubing conduit and annulus are hy

a slip set or donut that suspends and holds the top of the tubing in the wellhead.

n: a flanged fitting that supports the tubing string, seals off pressure between the casing and the outside of the tubing, and provides a connection that supports the Christmas tree.

n: A wellhead component that supports the tubing hanger and provides a means of attaching the Christmas tree to the wellhead.
