a theory of petroleum generation in which petroleum is thought to have formed from hydrocarbons trapped inside the earth’s crust when the earth was forming. See also Biogenic and Organic theories.

v: I. to take in and make part of an existing whole. 2. to recover liquid hydrocarbons from natural or refinery gas in a gas- absorption plant. The wet gas enters the absorber at the bottom and rises to die top, encountering a stream of absorption oil (a light oil) travelling downward over bubblecap trays, valve trays, or sieve trays. The light oil removes, or absorbs, the heavier liquid hydrocarbons from the wet gas. See bubble-cap tray, sieve tray, valve tray.

to fill part or all of the pore spaces.

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.

the wash oil used to remove heavier hydrocarbons from the gas stream.

n: the adhesion of a thin film of a gas or liquid to the surface of a solid. Liquid hydrocarbons are recovered from natural gas by passing the gas through activated charcoal, silica gel, or other solids, which extract the heavier hydrocarbons. Steam treatment of the solid removes the adsorbed hydrocarbons, which are then collected and re-condensed. The adsorption process is also used to remove water vapour from air or natural gas. Compare absorption.

n: A surface phenomenon exhibited by a solid (adsorbent) to hold or concentrate gases, liquids or dissolved substances(adsorptive) upon its surface, due to adhesion.

the attraction and holding of a layer of a chemical on the wall of a formation. Usually held by ionic charge or wetting preference.

remediation technique to strip volitile contaminants from contaminated ground water after a spill. Works to oxidize components and to activate bacteria that can digest hydrocarbons.

n pi: hydrocarbons that have a straight chain of carbon atoms. Compare aromatic hydrocarbons.

n: a series of open-chained hydrocarbons. The two major classes are d1e series with saturated bonds and the series with unsaturated bonds.

straight or branched chain hydrocarbons with single bonded carbon atoms. Describes most oils.

n: the distribution of oil or gas produced from a well per unit of time. In a state using proration, this figure is established monthly by its conservation agency.

the process of determining ownership of hydrocarbons delivered to the meter or LACT unit on a lease.
