Just imagine if this tank contained the same volume as a gas lift annulus !

"All gas lifted wells shall have two barriers to prevent release of the A annulus gas volume”
I think this video graphically shows why they reached that conclusion and recommendation.
For details of how best to implement the double barrier solution please take a look at:
