Little bit of trivia

Just a small piece of trivia for those interested, and to keep people positive re things to come.
Our purchase of the Roma Shelf assets from Origin Energy should be finalising in the next week or so, all being fair.
The assets contain the Newstead gas storage facility with a current capacity of 7.5 PJ (Ann 2/11/15)
Here's the trivia just to put that storage in real terms:
A cavern, approx. 215 mtrs deep with a diameter of around 80 mtrs, underground, is required to hold that much gas.
Armour will be considering the potential of increasing the capacity to 19 PJ.
