Interventek signs exclusive valve supply deal for Gulf of Mexico with PRT
Interventek Subsea Engineering has signed a two-year exclusive deal with Louisiana, US-based Professional Rental Tools (PRT) to supply its in‑riser Revolution valve for well intervention operations in the Gulf of Mexico.
Interventek’s Revolution shear and seal valve will be used to enhance PRT’s existing subsea systems offering.
“We are delighted that PRT has recognised the significant operational and safety benefits of our unique, next-generation Revolution valve design,” said Stuart Ferguson, chairman at Interventek.
“Deploying our valves in the Gulf of Mexico will allow us to gather additional subsea experience and an operational track record on the back of our already extensive technology trials, testing and application development. This is the first step towards broader subsea market adoption,” he added.
The PRT subsea spanner joint system interfaces with the rig blowout preventers, subsea tree vendor tubing hanger running tool (THRT), and downhole functions during installation, workover or removal of subsea completions.
The system is designed for deep water and high working pressure applications, and the addition of the Revolution valve enables the user to cut wire or coiled tubing introduced into the well and provides a seal from below after the cut.
The valve also offers pump-through capability to facilitate well kill operations.
The award-winning Revolution valve has multiple well control applications, as in a single device it uniquely provides the capability to quickly and reliably cut all types of intervention media whilst protecting the integrity of its seal.
The technology 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 and large bore applications.
External rotary actuators provide a superior cutting force for the very strongest of intervention media, and hydraulics are kept separate from the wellbore.
This simple, reliable design can be scaled to meet all well bore sizes and operating pressures, including 20,000psi, and it is quick to manufacture and provides easy access to components, thus reducing the cost of ownership.
“The design advantage of the Interventek Revolution valve has allowed it to be easily integrated into the PRT existing spanner joint system and offers our customers the additional benefit of being able to cut wireline or coiled tubing and then seal,” PRT COO and president, Patrick Placer commented.
