This paper will focus on well integrity standards and give practical examples on how they are applied for wells in the Norwegian Sea.
Further the paper will review how the standards are used for testing and verifying barriers in a well, and how well integrity on subsea and TLP (tension leg platforms) benefit with the introduction of annulus B monitoring.
Examples will present how barriers can be moved and testing time reduced, while still complying to standards and local regulations as well as making the well design more robust.
Data from a well using the annulus B monitoring system will be presented and explained to give an understanding how this can benefit subsea wells throughout life of well.
