Definition of Well integrity Well integrity process is:Application of technical , operational and

organizational solutions to reduce risk of uncontrolled release of well bore fluids through out the life cycle of a well, to avoid harm to people , environment and assets and the required barriers and assurance task in place to prevent this .

This well integrity standard addresses the operate phase of the well from well construct hand over to abandonment only.
