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.
