Post Montara/Macondo

Follow these recent accidents the matter of well integrity and barriers have received significantly more attention, and we see an increasing demand for understanding and conveyance of how safety is taken care of. The use of illustrations for this purpose tells a story of more than a thousand words and ensures that everyone has the same picture of the situation.

Well barrier schematics

The concept of making available well barrier illustrations have continuously been improved throughout the years and is now available to the industry as a powerful state of the art web application where the user can perform a large number of well specific adaptations, yet retain a strong and consistent graphical output.

It is believed that the well barrier schematics will add improved understanding to all stakeholders outside those working on the very specific engineering details of the well.

The application

The Wellbarrier web application offer a large library of samples from all types of well activities during the life span of the well, from drilling through well testing, completion, intervention and workover to plug and abandonment of the well.

The user can also build his own well configuration from scratch, making the well illustration 100% well specific.

The web application is today widely used in operations on the Norwegian continental shelf and subscribers in Europe, America and the Far East are now using the illustration tool.
