bpt vs esg, page-4

can you explain why they say "To put 2 tcf of gas into perspective, it is the equivalent of 330 million barrels of oil, and in dollar terms it has an in-ground value of about $33 billion ? with potentially for more upside because the Cooper Basin shale gas hunt has only just begun."

I am looking at the dollar value of 2 Tcf at 33 billion dollars as it says.

Are they using bad English as it only refers to the 2 Tcf and not the other possible gas in other areas of the land resource?
