Saint-Gobain Seals to Present Oil & Gas Technical Paper at NACE Corrosion Conference
Saint-Gobain Seals Presenting Oil & Gas Technical Paper On Next Generation of Materials for Sealing Solutions in Extreme Conditions at NACE Corrosion Conference
By: Saint-Gobain Seals
Currently, the oil & gas industry faces challenging requirements for applications within HPHT reservoirs. Sealing solutions have been rated as the technology with the largest gap to overcome these applications, primarily due to the polymers that are used for these applications. As a result, there has been an emphasis on the research and development of new materials that can withstand demanding conditions. In response to such needs, Saint-Gobain Seals has been developing their next generation of materials in order to fabricate the next generation of sealing solutions. Since there are severe limitations when using elastomeric seals, thermoplastic sealing solutions have emerged as a strong alternative due to their thermal and chemical resistant properties as well as their rapid gas decompression resistance. To solve durability issues and withstand HPHT conditions, Saint-Gobain Seals created specific thermoplastic formulations for their spring-energized seals and back-up rings in the form of their commercially available OmniSeal® seals (www.seals.saint-
Their technical paper will address the performance of the materials that are being confirmed by experimental work as well as a proprietary Finite Element Analysis (FEA) material model. The study on the impact of exposure at 30 kspi/250°C on mechanical properties of PTFE compounds as well as the extrusion behavior of thermoplastic back-up rings at HPHT conditions will be shared in the first section of the paper. The selected materials have also been exposed to 25% H2S concentration up to 200°C according to NORSOK M710 rev2 specification to guarantee their chemical resistance. The results of the qualification program at different level of H2S will be covered in the second section. The best performing materials have been selected to be used for the development and validation of sealing solutions on their custom-designed test rig, which strictly follows the testing protocol of API6A, Annex F PR2.
Saint-Gobain Seals has been requested on numerous occasions to share their research at oil & gas conferences;
