n: 1. A vertical, cylindrical vessel that recovers heavier hydorcarbons from a mixture of predominantly lighter hydrocarbons. Also called absorption tower. 2. A vessel in which gas is dehydrated by being bubbled through glycol. See absorb.

n: It refers to the row tube holding thezinky
material during the analysis of drilling fluid. Used to survey the content
of H2S.

a vertical, cylindrical vessel that recovers heavier (longer carbon chain) hydrocarbons from a mixture of lighter hydrocarbons.

n: See hydroxy aluminium.

chemicals which prevent hydrate crystals from sticking together and forming a larger mass.

water soluble polymers produced by bacterial action on carbohydrates.

a restriction in a profile near the bottom of the well that allows some gas expansion and holds a backpressure on the formation. Rarely used, but considered for hydrate control.

n: the active ingredient of slaked (hydrated) lime, and the main constituent in cement (when wet). Referred to as lime" in field terminology. Its symbol is Ca(OH)2

n: Ca(OH)2, white powder. The pH value of its saturated solution is 12.4. Usually used for depressant of inorganic salt, calcium mud and clearing excessive carbanion in drill fluid.

Ca(OH)2, slaked lime.

n: The collapsed mud shale due to hydrate expansion.

v: to remove water from a substance. Dehydration of crude oil is normally accomplished by treating with emulsion breakers. The water vapor in natural gas must be removed to meet pipeline requirements;a typical maximum allowable water vapor content is 7 pounds per million cubic feet (3.2 kilograms per million cubic metres) per day.

n: The cake formed by cement slurry leaking off free water.
