Aberdeen-based well intervention technology specialists, Interventek Subsea Engineering, have pushed the boundaries of oil and gas industry capability with the launch of their latest new product, an ultra-high pressure, high temperature (HPHT) version of their 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. 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. It uses Interventek’s award-winning Revolution valve technology, providing a step change in performance at a dramatically reduced cost due to a number of unique features.
The Revolution valve uses separate cutting and sealing components so that the seal is never compromised. Resilient seals avoid the use of vulnerable elastomer components for fluid containment, enabling use in HPHT applications. It is easily scaled to meet all well bore sizes, to cut all likely obstructions and its compact size means it is ideally suited to the challenging confines of in-riser interventions. External rotary actuators provide a superior cutting force and hydraulics are kept separate from the wellbore.
