n: vapor at its dew point

n: 1. a state of being filled or permeated to capacity. Sometimes used to mean the degree or percentage of saturation (e.g., the saturation of the pore space in a formation or the saturation of gas in a liquid, both in reality meaning the extent of saturation). 2. the condition of air when it contains the largest amount of water vapor it can possibly hold at a given temperature and pressure.

pressure at which vapor and liquid are in equilibrium. For oils, equal to the bubble point. For condensates, the dew point.

n: (SSU) a unit for measuring the viscosity of lighter petroleum products and lubricating oils. See Saybolt viscometel:

n: an instrument used to measure the viscosity of fluids, consisting basically of a container with a hole or jet of a standard size in the bottom. The time required for the flow of a specific volume of fluid is recorded in seconds at three temperatures (IOO.F-37.S.C, 130.F-54.4.C, and 210.F-9S.9.C). The time measurement unit is referred to as the Saybolt Second Universal (SSU).

n: a line or other mark on the scale of an indicating device corresponding to one or more defined values of the quantity measured.

n: the set of numbers marked on a scale that correspond either to the values of the quantity measured, defined by the scale marks, or that indicate only the numerical order of the scale marks.

n: 1. the zone included between the scale marks that corresponds to the maximum and minimum values of the scale. 2. the difference between the maximum and minimum values of the scale.

abbr: standard cubic feet.

standard cubic foot, a measurement at standard conditions of gas volume.

n: see wire-wrapped screen. screw packer n: a packer in which the packing element is expanded by rotating the pipe. It is used when it is not desirable to put tubing weight on the packer. scrub v: to remove certain constituents of a gas by passing it through a scrubber in which the gas is intimately mixed with a suitable liquid that absorbs or washes out the constituent to be removed.

n: The serial casing with mesh,which be situated at the bottom of oil string.
