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: a reaction in which an element has been changed into an unstable isotope during bombardment by neutrons.

near formation area is irradiated with neutrons that transform some nuclei into isotopes. The isotopes produced can be detected by radioactive energy levels and decay time. The original elements can be described from this behavior.

annular isolation sleeve.

n: a process for manufacturing components for 100-octane gasoline. An alkyl group is introduced into an organic compound either with or without a catalyst. Now usually used to mean alkylation of isobutane with propene, butenes, or hexenes in d1e presence of concentrated sulphuric acid or anhydrous hydrofluoric acid.

a reverse cracking process that convents hydrocarbon light ends (olefins) into longer chain, liquid fuels.

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.

a comparable reservoir with many similar characteristics (e.g., lithology, depositional environment, porosity, perm, drive mechanism, produced fluids, etc.) that can be used for behavior projections comparison studies.

differences in rock – segments showing different responses when measured.

n: The character that the formation presents different intension in different direction.
