Retrievable bridge plug receives V0 certification

cost in some of its challenging wells. All tests were undertaken at Peak’s new gas pressure testing facility located in Aberdeen, UK, and were independently witnessed and validated by a certified third party authority. Robin McGowan, chief technology officer at Peak Well Systems, said, “Proving V0 performance across such a wide operating range in a single test run without the need to break testing into smaller temperature increments is a huge achievement and demonstrates not only the seal’s robustness but also the technology’s unique capability relative to traditional seals.” The Simultra range was developed in response to an industry need for a high expansion, high performance plug suitable for gas wells and challenging applications. At its core is MetaPlex – a hybrid metal-elastomer seal that delivers both performance and improved recovery reliability. The MetaPlex sealing element expands further than conventional V0 sealing technologies, but retracts to a smaller- than-original outside diameter, and does not rely upon the memory of the elastomer to retract the seal for retrieval. It offers a larger internal flow diameter compared to conventional V0 elastomeric seals, making it suitable for other applications where restricted flow is an issue.

Peak Well Systems, a specialist in the design and development of advanced downhole tools for well intervention, has reached a milestone in the development programme for its Simultra range of retrievable bridge plugs. The range of available plugs has been extended into 5½" applications with the successful ISO-14310 V0 gas testing of the 5½" tool in 20lb API casing. The results of the testing showed repeatable zero bubble gas performance over a single test sequence that ranged from 175°C to 25°C, and from 7,500psi above to 7,500psi below the seal. Additional testing of the same 5½" Simultra plug to 10,000psi was expected to take place at a later date. Peak was commissioned to conduct the testing specifically by a leading international oil operator that is interested in utilising Simultra technology to reduce

The dual metal seal design protects the elastomer element from hostile well conditions, maintaining seal integrity even in extreme downhole environments and ensuring improved reliability and retrievability. Officially launched in November 2015, Peak has now successfully achieved V0 certification for its 4½" plug in 11.6lb to 15.1lb casing, as well as for its 5½" plug in 20lb, which is also suitable for 23lb casing. Peak aims to have the complete Simultra range, which will include a 7" plug, available for sale or rental by Q3 2016. Peak’s portfolio of products includes solutions for flow control, routine and high-deviation well intervention, extending or restoring well integrity, downhole data acquisition, heavy-duty fishing, wellbore clean-up and debris removal. The company has technology centres in Perth (Australia), Aberdeen (UK) and Dubai (United Arab Emirates), supported with sales and rental offices in Kuala Lumpur (Malaysia) as well as distribution agents.
