PolyVolve SWIVEL DS is the world's strongest and most durable swivel. It's patented stackable polymer bearing design allows an unlimited load bearing and durability capabilities.

Inclusion of PolyVolve SWIVEL DS in the drillstring above a liner or casing during deployment allows dynamic rotation to mitigate the negative effects of static friction and can significantly improve deployment capability. This provides operators with the utmost confidence of speedy, accurate and safe placement of their wellbore systems and can allow for longer more complex wells to be planned with confidence and executed safely.

PolyVolve SWIVEL DS is recommended for use in any application where the system deployment may be encumbered or hampered by excessive friction due to well conditions or wellbore geometry. It is ideally suited to assist with the controlled, precise and speedy deployment of liners and sand-face completions, TCPs, casing, perf and wash systems, and wellbore clean-up systems. The compliant nature of the bearing under bending load delivers excellent performance in high dogleg and deviated applications.

Operator Benefits

• Reduced static friction gives better weight transfer for speedy deployment
• Enhanced durability over alternative technology
• Compliant bearing excellent in bending for dogleg applications
• Safe, controlled & accurate deployment
• Reduced operational time
• Increased operational success

Benefits
• Rapid and effective single-trip BOP and riser cleaning
• Reduced BOP maintenance and nonproductive time
• Higher success rate and efficiency of BOP
• Allows short tripping with wellbore clean-up string
• Cleans even deep cavities
