"Every shale play presents unique geological challenges that have to be overcome. But that can only be done with a mixture of persistence and experimentation."

And therein hangs the long, sad tale of the Falcon. MAKO not the home run it was expected to be because, .....see above. Beetaloo likewise has required test wells and months and months of anaylsis. They all do. In the article it says about 1 in 3 of the shale plays in the US are big producers. That is where our hope has always lain - that at least one of our prospects (especially now that we have three) will ultimately prove itself one of those humongous producers, and preferably sooner than later.

China, Argentina and South Africa are all plausible candidates

Why no mention of Australia?
