n: the temperature at which the vapour pressure of a liquid becomes equal to the pressure exerted on the liquid by the surrounding atmosphere. The boiling point of water is 212ﾰF or 100ﾰC at atmospheric pressure (14.7 pounds per square inch gauge or 101.325 kilopascals).

the temperature at which the vapor pressure of the liquid is equal to the pressure exerted on it by the surrounding atmosphere.

n: The pressure of fluid decreases below saturated vapor pressure and forms jet with numbers of air bubble when the fluid passes through special nozzle. The air bubble forms domestic high pressure when striking the solid border.

n: the vapor pressure of a liquid at 100�F (37.78�C, 3l10K) as detennined by ASTM D 323-58, Standard Method of Test for Vapor Pressure of Petroleum Products (Reid Method).

n: condensate that has been stabilized to a definite vapor pressure in a fractionation system.

n: 1. a tool placed on a drill collar near the bit that is used, depending on where it is placed, either to maintain a particular hole angle or to change the angle by control- ling the location of the contact point between the hole and the collars. See packR:d-hole as- sembly. 2. a vessel in which hydrocarbon vapors are separated from liquids. 3. a fractionation system that reduces the vapor pressure so that the resulting liquid is less volatile.

n: A downhole tool which has minor interspace with borehole,usually be fixed on the drill string.

n: pressure measured relative to zero pressure. true vertical (TVD) n: the depth of a well measured from the surface straight down to the bottom of the well. The true vertical depth of a well may be quite different from its actual measured depth, because wells are very seldom drilled exactly vertical.

n: the pressure exerted by the vapor of a substance when the substance and its vapor are in equilibrium. Equilibrium is established when the rate of evaporation of a substance is equal to the rate of condensation of its vapor.

the pressure exerted by the gas phase (vaporized liquid) in equilibrium with the system conditions.
