a multiple completion in which the upper zone flows to the surface through the annulus formed by the casing and the deeper zone tubing. Usually used only in sweet, dry gas upper completions.

n: a hydrocarbon product that contains corrosion-inducing com- pounds in excess of the specification limits for a sweet product.

n: unrefined liquid petroleum. It ranges in gravity from 9. API to 55. API and in colour from yellow to black. and may have a paraffin, asphalt, or mixed base. If a crude oil, or crude, contains a sizeable amount of sulphur or sulphur compounds, it is called a sour crude;if it has little or no sulphur, it is called a sweet crude. In addition, crude oils may be referred to as heavy or light according to API gravity, the lighter oils having the higher gravities.

n: The petroleum which is not being processed.

n pi: chemical compounds containing an -S-S linkage. They are colorless liquids completely miscible with hydrocarbons, insoluble in water, and sweet to the doctor test. Mercaptans are converted to disulfides in treating processes employing oxidation reactions.

n: a qualitative method for detecting hydrogen sulfide and mercaptans in petroleum distillates. The test distinguishes between sour and sweet products.

n: the substant is made by fermenting to get rif of sweet and alkalize with tall and thendepositing and geing rid of calcium sulphate with subphurous acid ferrum and at last being oxidated by sodium bichromate

neutralizing acid production (sour gas) with sweetening agents, etc.

various, but generally the gas send to the pipeline after dehydrating, stripping and sweetening.

adj: having an absence or nearabsence of sulfur compounds, as defined by a given specification standard.

absence of hydrogen sulfide, H2S.
