Improved annulus integrity


Cflex® technology enables high-performance multistage cementing. Certified “gas tight” under ISO 14998 V0, and with a two-stage permanent lock system, Cflex® performs to the highest integrity standards.

Installing Cflex® at one or more casing joints gives operators flexibility, reliability and far greater confidence in cementing operations.

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 improves annular seal integrity and overcomes the shortcomings of previous stage cementing technology.
