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 process that uses a solution comprising 10 to 30 percent monoethanolamine, 45 to 85 percent glycol, and 5 to 25 percent water for the simultaneous removal of water vapour, H2S and CO2 from gas streams.

form: hydrogen sulphide.

hydrogen sulfide.

n: when drilling in sulphur field,an instrument that monitor the content of H2S alarms at the time of content of H2S exceed the safety level.

n: see trim.

n: responding to the intense corrosion action ,a packer is installed between the oil formation top and casing to protect the casing and a circulating sub is installed on the top of packer to circulate the inhibiter of H2S

high temperature, deep, high pressure or highly corrosive or erosive producing environments (e.g.: depth >20,000ft or 6100m, temp > 325oF or 163oC, pressure >20,000 psi, H2S or CO2 content).

a material that takes another material out of solution or the flow stream. Among most common are oxygen and H2S scavengers.

adj: containing or caused by hydrogen sulfide or another acid gas (e.g., sour crude, sour gas, sour corrosion).

H2S containing.

defined in NACE MR-0175/ISO 15156 as exposure to oilfield environments that contain H2S and can cause cracking of materials by the mechanisms addressed by NACE MR-0175/ISO 15156.
