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.

n: The number of treating chemical of drilling fluid that the adsorbent can adsorb when the adsorption is under balance.

n: The number of treating chemical of drilling fluid that the adsorbent can adsorb when the adsorption is under balance.

n: The process in which the bit continually breaks the formation and deepend the wellbore. It is controled by the driller who operates the brake crank and set down the drilling string to keep definite weight on bit.

n: The new set of journal bearing insert bit presented by America Hughes Company. It has the longer life and higher ROP than many kinds of former bits.

n: a fog caused by the movement of warm, moist air over a surface with a temperature less than the dew point of the air. Also called sea fog.

n: a method of asserting and gaining title to property against other claimants, including the owner of record.
