Aberdeen-based well intervention technology specialists, Interventek Subsea Engineering, have launched an ultra-high pressure, high temperature (HPHT) version of its Revolution safety valve for in-riser landing string systems.
This new shear and seal valve is able to withstand working pressures of 20,000psi and temperatures up to 350 degrees Fahrenheit.
There are currently no other 20K in-riser shear and seal safety valves on the market and the new product line was developed to support the industry as it advances into more challenging HPHT, deep water well environments, particularly in the Gulf of Mexico, Interventek noted.
Gavin Cowie, managing director at Interventek exp,lained: “Our new 20K in-riser Revolution valve is a natural extension of our uniquely reliable shear and seal technology. The 20K device maintains the superior cutting capability of previous Revolution valves and our unique resilient sealing provides the operator with a future proof, flexible HPHT solution, giving peace of mind as operating conditions become ever more challenging.
“As a young company with a game changing disruptive technology, we are pushing against people’s inbuilt preference to choose what they are used to – older, familiar, more conventional technology. But now that we are achieving traction in the market, and our products are proving themselves in the field, we are finding that clients are approaching us to deliver new solutions to industry challenges. Developing the 20K in-riser valve was not only to meet the HPHT need but also to demonstrate how new technology can exceed expectations. Our design is flexible and scalable and doesn’t suffer from the shortcomings of other valves so it was easy and natural for us to develop what we believe is a world-first.”
The 20K in-riser valve has a 5 1/8” bore size and is able to cut wireline and coiled tubing up to 2” x 0.203”, 148ksi tensile strength.
