Here's an article from last January where the CEO of Linc Energy himself walks back those reported estimates:
http://www.smh.com.au/business/20-tr...124-2d8zf.html
"‘‘That’s not our valution. I don’t know who did that but someone’s got a calculator out and come up with that number ... but we wouldn’t put a valuation on it at this stage. It’s too hard."
‘‘Obviously if you want to stand up there and come up with $US100 times 100 billion barrels, you’ll come up with a big number. That’s not how you value oil resources anyway.’’
‘‘
There is no certainty that any portion of the prospective resources estimated herein will be discovered. If discovered, there is no certainty that it will be commercially viable to produce any portion of the resources.’’
So, yeah.
The article linked by the OP that started this whole thread was written by this retard -
