Peak Well Systems (Peak), a leading specialist in the design and development of advanced downhole tools for well intervention, has reached a major milestone in the development programme for its SIMULTRA range of retrievable bridge plugs with the successful ISO-14310 V0 gas testing of the 4 ½ in. tool in 15.1 lb API pipe at an industry leading 10 000 psi and 175oC specification.
The results of the testing were very impressive showing zero bubble gas capability over a complete test cycle that exceeded 24 hrs in total duration.
Robin McGowan, Chief Technology Officer at Peak Well Systems, said: “This certification brings us closer to extending the operating envelope for plug systems that are vital within our industry and for which there is strong demand.
No other competitor has a plug capable of achieving this specification whilst meeting the SIMULTRA standard for retrievability and running clearance.”
The SIMULTRA range incorporates MetaPlex technology, a unique hybrid metal-elastomer seal that delivers both exceptional performance and improved recovery reliability.
The MetaPlex sealing element expands significantly further than conventional V0 sealing technologies but retracts to a smaller-than-original outside diameter (OD) and does not rely upon the memory of the elastomer to retract the seal for retrieval. It offers a much larger internal flow diameter compared to conventional V0 elastomeric seals, making it ideal for other applications where restricted flow is an issue. Furthermore, the dual metal seal design protects the elastomer element from hostile well conditions maintaining seal integrity even in the most extreme downhole environments ensuring improved reliability and retrievability.
All tests were undertaken at Peak’s new state-of-the-art gas pressure testing facility located in Aberdeen and were witnessed and validated by a certified third-party authority.
