tallaganda reserves 3 tcf plus?

THIS IS ONLY MY OPINION BASED ON PUBLIC INFORMATION. (Please do your own research)

Please focus on the words "after making a huge discovery in the Carnarvon Basin"
More importantly focus on the words "A company spokesperson says it is a world class deposit with significant potential and ..."

Apparently "World Class Deposit" has a definite meaning in the oil industry#

According to my reasoning Tallaganda is a very large gas deposit.
But what is the equivalent of barrels to Tcf?

If "World Class" is half a billion #plus# barrels the Tallaganda Reserves must be 3 Tcf plus #ie 500,000,000 X 6#
Can anyone fault my maths?
PLEASE do your own research.
