EnDura® V91K Now Approved to Shell MESC SPE 85/301
EnDura® V91K has for many years been trusted to deliver reliable sealing performance in the most critical oil & gas applications. EnDura® V91K is now approved to Shell MESC SPE 85/301 following a successful Type Acceptance Test (TAT).
This achievement allows Precision Polymer Engineering to collaborate with partners specifying the Shell MESC SPE 85/301 standard, and represents another technical landmark in the continual development of the EnDura® range of oil and gas sealing materials.
The Shell MESC SPE 85/301 standard concerns explosive decompression (ED) resistance in high temperatures, and subjects test samples to more challenging test conditions than other standards – including ISO 23936-2 and NORSOK M-710. For example, NORSOK M-710 tests are carried out at 100°C, whereas the equivalent tests under Shell MESC SPE 85/301 are conducted at 150°C. Under Shell TAT test conditions, EnDura® V91K O-rings achieved a ‘0000’ rating – which is indicative of zero damage to the sample.
Third party testing carried out for Precision Polymer Engineering on EnDura® V91K was able to show data for sour gas performance at temperatures and time periods greatly exceeding those required for Shell MESC SPE 85/301. Requiring 150°C for 24 hours to pass Shell TAT, PPE successfully tested EnDura® V91K at 150°C for 1344 hours, as well as 175°C for 1296 hours and 200°C for 168 hours.
“Precision Polymer Engineering recognises the need for approvals and qualifications to meet not only industry standards, but those of end users and Supermajors”, said Chris Allan, Product Manager for Oil and Gas at Precision Polymer Engineering.
“EnDura® V91K offers a perfect fit to meet and invariably exceed the requirements set out by Shell Global Solutions for Type Acceptance Testing according to SPE 85/301, and we are now proud to be able to offer this material to markets requiring this most stringent of approvals.”
EnDura® V91K is a high performance fluoroelastomer which combines excellent ED resistance with extreme low temperature performance (operating temperature between -41°C to +225°C), making the material grade an ideal choice for downhole, surface and subsea oilfield equipment. The Shell TAT approval applied to various products manufactured from EnDura® V91K, including O-rings, S-Seals, T-Seals, packers and chevron stacks.
