THE WOODLANDS, Texas – Sandvik representatives were available at the Deep Offshore Technology International conference and exhibition to discuss the company’s drilling and well completion; subsea infrastructure; and well intervention services.
Within its drilling and well completion line, Sandvik has a strategic alliance with Tenaris to combine its OCTG alloys with Tenaris’ connectors to combat hot and sour drilling environments. As a result, Sandvik SAF 2507 allows for corrosion-resistant tube with thinner tube walls than 316L stainless steel, Sandvik said, noting that a major contractor had achieved 70% weight reduction when using hydraulic tube lengths from the material in a drilling riser.
In its subsea infrastructure product line, Sandvik is working to develop corrosion resistant allows that can withstand 20,000 psi. It currently offers the Sandvik SAF 3207 hyper-duplex allow, which provides for what the company says is greater yield strength, corrosion resistance, and fatigue properties. The company has provided more than 300,000,000 ft (100,000,000 m)
The Clikloc connector is a self-centering device that Sandvik says saves 80% in make and break times during well intervention. It can be produced in the Sandvik SAF 2507 super duplex, and eliminates the hazard of falling nuts and bolts. It also aims to increase efficiency by eliminating the need for threaded and flanged connections on workover risers.
