Cflex technology enables high-performancemultistage cementing. Qualified “gas tight” equivalent to ISO 14998 V0:2013 and with a permanent lock system, Cflex performs to the highest integraity standars.

Despite advances in cement technology, annulus integrity is one of the biggest challenges facing the industry, both in terms of frequency and impact. The Cflex cementing system improved annular seal integrity and overcomes the shortcomings of previous stage cementing technology. In designing Cflex, our engineers focused on four key areas, integrity, flexibility, efficiency and performance.

Application
• Controlled, secure and selective access to casing annulus
• Multistage cementing
• Annulus cleanout
• Fracturing

Features
• Sealing system qualified to ISO 14998 V0 equivalent
• High burst, collapse, torque and tensile ratings
• Full bore ID matches casing ID and slim OD
• Closing utilising push/pull movement
• Permanent close function
• Unlimited number can be installed in liner or casing string
• Can be shifted with high differential pressure without damaging seal
• Large port flow area; 4.4 sq.in. minimum
• Inner sleeve hard coated to reduce wear; anti-rotation system

Benefits
• Improved annulus integrity and zonal isolation
• Security and confidence in gas tight sealing capability and mechanical integrity
• Easy installation and single-trip operation of multiple Cflex®
• Precise and conclusive operation for open, close and lock; no risk of accidental lock
• Improved operational efficiency and effectiveness
• Versatility and flexibility for multiple applications
• Slim design minimises ECD effects
• Large flow area ports maximise possible flow rate
