Sour Gas Testing

In the O&G industry, chemical environments can be brutal.  Argen has the facilities, expertise and experience to get the job done right.

Selection and qualification of materials in the O&G industry requires subjecting the materials to simulated operating conditions. In many cases the environment comprises sour gas (hydrogen sulfide, H2S), typically in combination with other gases. Argen Polymer LLC carries out sour gas aging of materials at our new 15,000 sq. ft. facility.  We can follow up the aging with mechanical and analytical testing to provide our clients with results to make decisions, whether for standard test qualification or for gaining fundamental understanding of the system.  Our staff have over 25 years of experience handling H2S at high pressure and temperature.

Capabilities

  • Exposures in H2S / CO2 / CH4 and multiphase mixtures
  • Pressures to 15,000 psig
  • Temperatures to 320 °C
  • Temperature and pressure cycling on seals
  • Full datalogging
  • Multiple large vessels capable of aging several materials simultaneously
  • Dozens of smaller vessels for segregated aging

Example Test Standards

  • ISO 23936
  • API 6A conditions EE/FF and GG/HH
  • NORSOK M-710
  • API TR 6J1
  • API 17D
  • Customized sour RGD

Chemical & Mechanical Assessments

Simulated environment aging is typically followed by assessment of changes in physical and mechanical properties, such as tensile, flexural, compression, hardness, specific gravity, and others.

These properties are evaluated according to the relevant ASTM or ISO standards, on state-of-the-art, calibrated instruments. Additional techniques such as TGA, DSC, and DMA can be employed to gain additional insight into polymer degradation.

Safety & Experience

Because safety is a priority, we have invested in proper facilities and environmental controls. We operate a dedicated stand-alone building that is remotely monitored and sensored. All exhaust gases from this building are treated in a 16 ft tall caustic scrubber system.
