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.

v: The natural gas which is consisted of a number of hydrogen sulphide and carbon dioxide kick

n: a chemical family of specific organic compounds, including monoethanolamine (MEA),diethanolamine (OEA),and triethanolamine (TEA). These chemicals, and proprietary mixtures containing them and other amines, are used extensively for the removal of hydrogen sulphide and carbon dioxide from other gases and are particularly adapted for obtaining the low acid gas residuals that are usually specified by pipelines.

n: any of several compounds employed in treating natural gas. Amines are generally used to remove hydrogen sulphide from water solutions and carbon dioxide from gas or liquid streams.

n pi: bacteria that do not require free oxygen to live or that are not destroyed by its absence. Under certain conditions, anaerobic bacteria can cause scale to form in water-handling facilities in oilfields or hydrogen sulphide to be produced from sulphates.

n: Used in the condition of countering hydrogen sulphide, usually from surface to 1800m.

n: a method of pairing two persons for their mutual aid or protection. The buddy system is used to ensure that each crew member is accounted for, particularly in situations where hydrogen sulphide may be encountered.

n: a black crystalline compound of iron and sulphur (FeS) produced in petroleum operations from the reaction of hydrogen sulphide (H2S) and the iron (Fe) in steel. Also called iron sulphide.

n: 1. a piece of cloth. rope. or nylon strand used to mart the wireline when swabbing or bailing. 2. an indicator of wind direction used during drilling or workover operations where hydrogen sulphide (sour) gas may be encountered. v:1. to signal or attract attention.2. in swabbing or bailing. to attach a piece of cloth to the wireline to enable the operator to estimate the position of the swab or bailer in the well.

n: the fibaric belt or rope binded on the cable during pumping or fishing


marking the pipe or wireline with a paint stripe.

n: the removal of hydrogen sulphide and carbon dioxide from raw gas or the green gas stream.
