19/01/2021 - VAM®High pressures. Extreme temperatures. Deep offshore projects present some of the toughest challenges in the oil and gas industry. With reservoir pressures beyond 15,000 psi, equipment manufacturers are being challenged to design specific products for these complex wells, including new pipe dimensions, accessories and connections.
Improving performances on market-known solutionsSince VAM® SLIJ-3 was specifically designed with the requirements of 20K projects in mind, it is the perfect fit for complex well architectures that must handle pressures up to 20,000 psi and temperatures up to 350°F (175°C).
A combination of winning features“The VAM® SLIJ-3 design is qualified to a larger envelope than what was previously available and has passed the latest and most stringent testing programs in the industry – such as API RP 5C5: 2017 CAL-IV,” explains Alan Fothergill, the Product’s Lead Engineer and Designer. “We’ve improved the thread design so it’s better for deep-stabbing and smooth make-up, has better galling resistance, and can withstand higher axial loads.”
The optimized design offers greater stability during loading conditions, so there’s less movement of seals. We’ve also improved the geometry of the metal-to-metal seals so we can have tighter seal contact, which is helpful at high pressures.Alan Fothergill VAM® SLIJ-3 Lead Engineer and Designer
A pragmatic approach to product developmentThe idea for VAM® SLIJ-3 was first explored several years ago, when expert teams were working to identify new concepts for the next generation of semi-flush products. “Our approach was very pragmatic,” explains Daly Daly, Vallourec’s Senior Technical Sales Manager for offshore US operators, who worked on the product from the very beginning.
Putting the connection to the testThe involvement of clients in the development of new products is often crucial. In this case, some of the US oil industry’s biggest operators played a major role in the development of VAM® SLIJ-3.
Looking to the future
Our goal is to make VAM® SLIJ-3 the go-to connection for intermediate and production casing strings where tight clearance and proven gas sealability under critical loadings are required. It complements Vallourec’s full offering for the deep offshore market, which includes specific pipe dimensions and accessories.Daly Daly Senior Technical Sales Manager for offshore US operators
In addition, while it is currently offered with standard dopes, VAM® SLIJ-3 is in the process of being validated with CLEANWELL®, our dope-free solution, reaching a truly rig-ready, next-generation solution. This will simplify the management of the product for our clients and bring them significant added value which, of course, is always our ultimate aim.Céline Sches VAM® SLIJ-3 Project Manager
