Certain oilfield polymers exposed to fluids containing hydrogen sulfide (H2S) will age chemically, with the rate of deterioration determined by H2S concentration and temperature. The resulting irreversible alteration in material property levels can have significant detrimental consequences for the functional performance of the part in an application (e.g., a seal). ²ÝÁñÉçÇø’s dedicated sour service teams can evaluate the performance of elastomers, thermoplastics and composites in sour fluids in accordance with standards such as NORSOK (M-710), ISO (23936, 10423), API (6A, 16C) and NACE (TM0187, TM0296).

²ÝÁñÉçÇø has more than 25 years of experience of delivering testing solutions for polymeric materials used in a huge range of Oil & Gas sector upstream and downstream applications.Ìý

H2S is a toxic gas present in many fields throughout the world, sometimes at very high levels. Seals and other polymeric components must be specified and qualified appropriately to established international standards. In addition, ²ÝÁñÉçÇø can offer significant experience in designing and executing custom sour fluid exposure programs to meet demanding client requirements for both material evaluation/qualification, and functional testing.

Our Engaged Experts can evaluate non-metallic materials used in your offshore, renewable, and oil & gas applications. Our staff have contributed to both ISO and NORSOK standards development and are members of the relevant ISO Working Group committee. ²ÝÁñÉçÇø has run two internationally supported JIPs in the area of oilfield polymers: SOUR and SOUR2.
