Abstract
Degradations or interruptions of the original well barrier elements might occur at offshore wells after some time in operation. Experience from the Norwegian Continental Shelf has shown that these prob-lems are not always treated as thoroughly as expected by the parties involved. This paper presents an ap-proach for an efficient visualization and description of interrupted well barriers, basically to increase the well barrier control and management. By mapping the history of operational demands and load picture of the well in combination with the status of well barriers, a consistent basis for evaluations is obtained. The main inten-tion is thus to realize the real well problem and its underlying causes in a controlled and systematic manner. Then, the responsible parties involved can take action more accurately according to the type of failure that has been revealed.
