n: (NSWA) association of producers of wells that yield ten barrels or less of crude petroleum a day. Its official publication is National Stripper Well Survey. Address: 825 Petroleum Bldg.;Wichita Falls, TX 7630 I;(817) 766-3870.

abbr: National Stripper Well Association.

n: a device with an elastomer packing element that depends on pressure below the packing to effect a seal in the annulus. Used primarily to run or pull pipe under low or mederate pressures, this device is not dependable for high differential pressures. Also called a stripper.

a seal between or around equipment to isolate pressure or areas within the well. .

n: a preventer having a unit of packing material whose closure depends on well pressure coming from below. It is used primarily to strip pipe through the hole or allow pipe to be moved with pressure on the annulus.

n: a device closed around the rods when the well may flow through the tubing while the rods are being pulled. It is a form of blowout preventer.

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: 1. a well nearing depletion that produces a very small amount of oil or gas, usually ten barrels per day or less. 2. a shipper head. 3. a column wherein absorbed constituents are shipped from absorption oil. The term is applicable to columns using a shipping medium, such as steam or gas.

the seal at the top of the BOP around coiled tubing or pipe during snubbing.

n: a blowout prevention device consisting of a gland and packing arrangement bolted to the wellhead. It is often used to seal the annular space between tubing and casing.

n: A kind of blowout hookup,usually used to seal off the annulars space between casing and oil tube.
