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: The drill pipe made by alloy of titanium and aluminium. It is lighter than the isometric drill pipe made by steel. It improves the drilling depth of rig, has good fatigue resistence and can absorb shake when connected above the drill collar.

gravity n: specific gravity as measured by the Baume scale. Two arbitrary scales are employed: one for liquids lighter than water and the other for liquids heavier than water. This scale is also used to describe the density of acid solutions.

n: either of two arbitrary scales-one for liquids lighter than water and the other for liquids heavier than water-that indicates specific gravity in degrees. bbl abbr: barrel. bbV acre-ft abbr: barrels per acre-foot. bbVd abbr: barrels per day. Bcf abbr: billion cubic feet. Bcf/d abbr: billion cubic feet per day. b/d abbr: barrels per day;often used in drilling reports. BID abbr: barrels per day. BOC abbr: bottom dead centre

breakdown of a heavier oil to a lighter hydrocarbon by bacterial action.

n pi: 1. the liquids and the residue that collect in the bottom of a vessel (such as tank bottoms) or that remain in the bottom of a storage tank after a period of service.2. the residual fractions remaining at the bottom of a fractionating tower after lighter components have been distilled off as vapours.

n: a workover performed with a small-diameter tubing work string inside the normal tubing. Equipment needed is essentially the same as that for a conventional workover except that it is smaller and lighter.

n: the hydrocarbon liquid lighter than kerosene that can be recovered by catalytic or thermal cracking in a refinery.

n: I. the property of atomic nuclei of having the probability of collision with a neutron. The nucleus of a lighter element is more likely to collide with a neutron than is the nucleus of a heavier element. Cross section varies with the elements and with the energy of the neutron. 2. a geological or geophysical profile of a vertical section of the earth.

n: unrefined liquid petroleum. It ranges in gravity from 9. API to 55. API and in colour from yellow to black. and may have a paraffin, asphalt, or mixed base. If a crude oil, or crude, contains a sizeable amount of sulphur or sulphur compounds, it is called a sour crude;if it has little or no sulphur, it is called a sweet crude. In addition, crude oils may be referred to as heavy or light according to API gravity, the lighter oils having the higher gravities.

n: The petroleum which is not being processed.
