Zusammenfassung:	A method for well integrity management on a well having at least one surface valve and a surface controlled sub-surface safety valve includes closing the at least one surface valve, applying a predetermined pressure to the at least one surface valve, analyzing a pressure loss across the at least one surface valve, and testing the surface controlled sub-surface safety valve for functionality. Functionality testing of the surface controlled sub-surface safety valve includes opening and closing the surface controlled sub-surface safety valve using a control panel. The method further includes classifying the well as operable or inoperable based on the pressure loss across the at least one surface valve and the functionality of the surface controlled sub-surface safety valve.
