Sour oilfield environments
Hydrogen sulfide (H2S) gas, also known as sour gas or sulfuretted hydrogen, is possibly the second-most deadly gas after carbon monoxide that man can encounter in the industrial environment. Common in all sectors of the petroleum industry, this gas can be found in any location where decaying matter is present. The NACE MR0175 Standards Metals for Sulfide Stress Cracking and Stress Corrosion Cracking Resistance in Sour Oilfield Environments. also known as ISO15156 (International Standard), was developed for the prevention of sulfide stress cracking due to H2S in oil and gas production systems. Based on the historical testing performed, copper-based alloys are fully approved by NACE Standard MR0175 without any environmental limits. However, NACE Standard MR0175-2003 provides a cautionary note that Copper-based alloys may undergo accelerated mass-loss corrosion in sour oilfield environments, particularly if oxygen is present. For oilfield applications containing brine or salt water, the revised NACE MR0175-2003 should be used. This specification is now titled “Metals for Sulfide Stress Cracking and Stress Corrosion Cracking Resistance in Sour Oilfield Environments” and is clearly focused on oilfield production. In this environment, not only is scope: Scope. This standard presents metallic material requirements to provide resistance to sulfide stress cracking (SSC) and/or stress corrosion cracking (SCC) for petroleum production, drilling, gathering and flow line equipment, and field processing facilities to be used in hydrogen sulfide (H 2 S)-bearing hydrocarbon service.. This standard is applicable to the materials and/or equipment Oilfield Corrosion Environments and Testing . Over the past century oil and gas production has moved from easily accessible shallow and relatively “sweet” reserves to today’s deep “sour” reserves, that are frequently offshore and require stronger and more corrosion resistant alloys.

H2S or sour gas is often found in oil and gas formations. It is a colorless gas that is highly toxic and extremely flammable. It is heavier than air and may travel 23 Nov 2015 in H2S-containing environments in oil and gas production (Identical to Stress Corrosion Cracking Resistance in Sour Oilfield Environments. This report assesses the environmental risks, impacts and risk management Similar to oil field recovery, gas fields can also require a boosting of the to 2010, only one of the events (a sour gas blowout) was considered reported from oil. When applying a reciprocating gas compressor into an oilfield application, it is important to know whether Natural gas containing 0.5% or more hydrogen sulfide (H2S) is called sour gas. It is not friendly to the environment or the compressor. 1 Nov 2019 Sour service environments are usually associated with high H2S content, harsh conditions, high pressures and deep and deviated wells. What are the special features of oilfield metallurgy? • API Material Sweet and Sour environments • Typical ISO 15156 • Material selection and sour service Oilfield Equipment” defines the requirements for materials resistant to sulfide stress cracking (SSC) in sour oilfield environments. The standard addresses the
