tony bourke on lateline

Interesting inteview tonight with Tony Bourke on lateline re. the CSG Industry.
He said each aquifer would be tested to see if it was sealed or porous and thus have artesian water leaking back into the coal seam after the water has been extracted.
If this was the case the coal seam would have to be re pressurised or the water re injected after the gas had been extracted, this would be a very expensive process.
This made me think that BOW is more valuable as it does not have these problems.
We should have a conga-line of companys wanting BOW's trouble free gas ground.
