Materials, Coatings, Elastomers & Completion Fluids Testing for Oil & Gas, Subsea and Industrial Applications
A single material failure in a high-pressure, high-temperature environment can trigger catastrophic equipment loss, well integrity incidents, and significant financial liability. As one of the leading HPHT autoclave testing laboratories in UAE, we provide precision simulation and evaluation of how materials, coatings, elastomers, and completion fluids perform under extreme downhole and process conditions — before they are deployed in the field. Our advanced autoclave testing facility is equipped with high-pressure, high-temperature testing vessels capable of simulating aggressive sour and sweet service environments in compliance with ASTM, NACE, NORSOK, and API standards. By providing comprehensive characterization of corrosion resistance, material degradation, and coating performance, we help operators and manufacturers qualify materials with confidence. We deliver detailed, data-driven test reports required for material qualification, fitness-for-service assessments, regulatory submissions, and engineering design validation.Our Core HPHT Autoclave Testing Services Include

Why HPHT Autoclave Testing is Important?
Sour Service Material Qualification (H₂S Environments)
Sour service environments — characterized by the presence of hydrogen sulfide (H₂S) — represent one of the most aggressive and dangerous conditions encountered in oil and gas production. Materials exposed to H₂S under high pressure are susceptible to sulfide stress cracking (SSC), hydrogen induced cracking (HIC), and stress-oriented hydrogen induced cracking (SOHIC), which can lead to sudden and catastrophic failure with little warning. At METS Lab, we conduct rigorous HPHT autoclave testing to simulate downhole sour conditions and qualify metals, alloys, and non-metallic materials against internationally recognized sour service standards. Our sour service testing is conducted in compliance with:- NACE TM0177 — Standard Test Method: Laboratory Testing of Metals for Resistance to Sulfide Stress Cracking and Stress Corrosion Cracking in H₂S Environments
- NACE TM0284 — Evaluation of Pipeline and Pressure Vessel Steels for Resistance to Hydrogen-Induced Cracking
- ASTM G111 — Standard Guide for Corrosion Tests in High Temperature or High Pressure Environment, or Both
- NACE MR0175 / ISO 15156 — Petroleum and Natural Gas Industries — Materials for Use in H₂S-Containing Environments in Oil and Gas Production
Coating & Lining Performance Testing
Internal coatings and linings in pipelines, vessels, valves, and downhole tools must withstand extreme combinations of pressure, temperature, chemical exposure, and mechanical stress over extended service lives. Coating failures in HPHT environments result in accelerated substrate corrosion, production contamination, and costly intervention operations. At METS Lab, we evaluate organic and inorganic coatings and linings under simulated HPHT service conditions to verify adhesion, chemical resistance, and integrity prior to deployment. Our coating and lining testing is conducted in accordance with:- NACE TM0185 — Evaluation of Internal Plastic Coatings for Corrosion Control of Tubular Goods in an Aqueous Flowing Environment (HPHT Immersion Testing)
- NACE TM0274 — Dynamic Corrosion Testing of Metals in High-Temperature Drilling Fluids
- ISO 15741 — Paints and Varnishes — Friction-Reduction Coatings for the Interior of On- and Offshore Steel Pipelines for Non-Corrosive Gases
- ASTM G111 — Corrosion Tests in High Temperature or High Pressure Environments
- NORSOK M-501 — Surface Preparation and Protective Coating — qualification and performance requirements for coatings used in the Norwegian oil and gas sector
Elastomer & Non-Metallic Material Testing
Elastomers, seals, O-rings, gaskets, and polymer-based components are critical to well integrity across surface and subsea systems. Exposure to HPHT conditions combined with aggressive chemical environments causes swelling, softening, hardening, and explosive decompression damage in elastomeric materials. At METS Lab, we perform high-pressure fluid immersion and rapid gas decompression testing to fully characterize elastomer performance under realistic service conditions. Our elastomer testing is conducted in accordance with the following standards:- NORSOK M-710 — Qualification of Non-Metallic Sealing Materials and Manufacturers — the primary global standard for qualification of elastomers for subsea and downhole applications
- NACE TM0187 — Evaluating Elastomeric Materials in Sour Gas Environments — immersion and physical property change assessment in H₂S-containing fluids
- ISO 23936-1 — Petroleum, Petrochemical and Natural Gas Industries — Non-Metallic Materials in Contact with Media Related to Oil and Gas Production — Part 1: Thermoplastics
- ISO 23936-2 — Non-Metallic Materials in Contact with Oil and Gas Production Media — Part 2: Elastomers
- ASTM D471 — Standard Test Method for Rubber Property — Effect of Liquids
Completion Fluid & Chemical Compatibility Testing
Completion, workover, and drilling fluids must remain stable, chemically compatible with downhole materials, and non-damaging to reservoir formations under HPHT conditions. Incompatibility between fluids and materials can cause accelerated corrosion, seal degradation, scale deposition, and formation damage. At METS Lab, we evaluate fluid stability, inhibitor performance, and material compatibility through controlled autoclave immersion and dynamic flow testing. Our fluid and chemical compatibility testing is conducted in accordance with the following standards:- NACE TM0298 — Evaluating the Compatibility of FRP Pipe and Tubulars with Oilfield Environments
- API 6A — Specification for Wellhead and Christmas Tree Equipment — material performance and pressure testing requirements for surface wellhead components
- API RP 13B — Recommended Practice for Field Testing Water-Based Drilling Fluids
- ASTM G111 — Corrosion Tests in High Temperature or High Pressure Environments
- ISO 11960 — Petroleum and Natural Gas Industries — Steel Pipes for Use as Casing or Tubing for Wells
Downhole & Wellhead Equipment Material Qualification
Wellhead components, completion tools, packers, valves, and subsea equipment must be rigorously qualified for service in specific pressure, temperature, and chemical exposure conditions. Regulatory requirements and operator specifications increasingly demand documented material qualification data from third-party accredited testing laboratories. At METS Lab, we provide comprehensive material qualification programs aligned with oil and gas industry specifications. Our equipment material qualification testing is conducted in accordance with:- API 6A — Specification for Wellhead and Christmas Tree Equipment — including material class, temperature class, and product specification level (PSL) testing
- API 6DSS — Specification for Subsea Pipeline Valves — material and performance requirements for deep-water service
- NACE MR0175 / ISO 15156 — Material requirements for sour service across all wellhead and completion equipment
- NORSOK M-710 — Qualification of elastomeric seals for subsea wellhead and completion equipment
- API 11D1 — Specification for Packers and Bridge Plugs — qualification and performance testing
