8. A method for well integrity management on a well having a tubing annulus, the method comprising:
injecting gas into the tubing annulus via a gas lift mandrel;
analyzing an annulus pressure in the injected tubing annulus;
running a bleed down build up test on the tubing annulus when the annulus pressure is less than a maximum allowable working operating pressure;
analyzing a subsequent annulus pressure after the bleed down build up test;
determining a presence of fluid returns after the bleed down build up test;
running a communication test between the tubing annulus and a casing annulus when the subsequent annulus pressure is greater than an error pressure; and
classifying the well as operable or inoperable based on the annulus pressure, the subsequent annulus pressure, the fluid returns, and the communication test.
