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.

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.

n: a group of compounds used to dehydrate gaseous or liquid hydrocarbons or to inhibit the formation of hydrates. Glycol is also used in engine radiators as an antifreeze. Commonly used glycols are ethylene glycol, diethylene glycol, and triethylene glycol.

a hydrate inhibitor or freeze-up preventer.

n: a method of squeeze cementing in which cement is pumped in and the pumps are stopped for a few minutes. Pumping is started and stopped until the desired pressure is obtained.

a cement squeeze technique where the cement is squeezed into a channel or leak at a low rate, then allowed to sit and dehydrate by leakoff, before again raising the pressure. The action gradually builds a dehydrated cement node that blocks the channel.

n: a kind of sealing slurry with high solid content and high filter loss,made from inactive substance and bentonite and when injected into the leaking layer the solid will dehydrate at once so as to pack the leaking formation

a collection of materials including cutting and/or fill that dehydrates or is held by pressure and stops to circulation of fluid in a wellbore.

v: see sand out.

to dehydrate a sand slurry to a point where the sand is no longer moveable.

n: 1. a gas containing water, or a gas that has not been dehydrated. 2. a rich gas.

a hydrocarbon gas with heavier ends (C2+).
