n: the theory that minerals such as oil and gas are fully owned in place before they are extracted and reduced to possession. Despite this theory, title to oil and gas may be lost by legitimate drainage and by the rule of capture. Also called ownership in place. See rule of capture.

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 gasoline extracted from natural gas by putting the gas into contact with oil in a vessel and subsequently distilling the gasoline from the heavier oil.

gasoline extracted from wet natural gas by putting the gas in contact with oil.

n: a gas that forms an acid when mixed with water. In petroleum production and processing, the most common acid gases are hydrogen sulphide and carbon dioxide. Both cause corrosion, and hydrogen sulphide is very poisonous.

n: The mixture made by gas and water presents acidity. The gas is acid gas. The usual acid gases are hydrogen sulphide and carbon dioxide in oil and gas drilling. Both of them are acrid and hydrogen sulphide is very toxic.


any produced gas, primarily H2S and CO2 that form an acid when produced in water.

n: an acid treatment in which an acid mixture is circulated through a wellbore to clean it.

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.

an essentially inert mixture of particles of a particular size range.

n: diving in which a diver uses a normal atmospheric mixture of oxygen and nitrogen as a breathing medium. It is limited to depths less than 190 feet (58 metres) because of the dangers of nitrogen narcosis;however, dives with bottom times of 30 minutes or less may be conducted to a maximum of 220 feet (67 metres).

n: the distance from the normal level of the sea surface to the bottom of the hull or base of an offshore drilling platform or rig.

n: The distance from normal sea level to drill platform when marine drilling.

the clearance between the highest water surface that occurs during the extreme environmental conditions and the underside of the deck.

n: a body of air that remains for an extended period of time over a large land or sea area with uniform heating and cooling properties. The air mass will acquire characteristics (such as temperature and moisture content) of the underlying region.
