n: The treating chemical
loss during manufacturing or purifying drilling fluid agent according to the principle of absorption.

n: material of high specific gravity formed during the chemical refining treatment of oils by sulphuric acid and usually separable by settling or centrifuging. Also called acid tar.

n: a method by which petroleum-bearing limestone or other formations are put into contact with an acid to enlarge the pore spaces and passages through which the reservoir fluids flow.

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

v: to treat oil-bearing limestone or other formations with acid for the purpose of increasing production. Hydrochloric or other acid is injected into the formation under pressure. The acid etches the rock, enlarging the pore spaces and passages through which the reservoir fluids flow. Acid also removes formation damage by dissolving material plugging the rock surrounding the wellbore. The acid is held under pressure for a period of time and then pumped out, after which the well is swabbed and put back into production. Chemical inhibitors combined with the acid prevent corrosion of the pipe. acid recovery plant n: plant for therecovery of sulfuric acid from acid sludge.

n: CH2=CHCOOH, colourless and irritant smell liquid, has corrosiveness. It is the important material for treating chemical.

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.
