Huge amounts of Coal Seam Gas bubbling in Australian River

Comment hidden because you are ignoring dag.(show it anyway)

Pretty sure that coal seam gas has been extracted in Australia for a while now.

Where the fuck is this!!???
I didnt think we had this crap in Australia yet...when did this happen??

The Govt. rolled over on this one, CSG fracking has been well under way for a while now in Aus. I read a while back a commission was setup to examine the risks of drilling, and the Greens wanted a moratorium until the commission was complete (5 years), but not sure of the outcomes of that.

I know bugger all about this, but wouldn't this be actually useful for something? Do they just let it get out like this with no care as they're after other things, or can they not control this when using fracking?

Yes, this is part of the new gas extraction craze taking off around the world. In many cases, the natural gas, including methane, isn't worth collecting, it is easier to just burn it then to try and sell it. Usually they are after the liquid hydrocarbons in these new deposits that horizontal mining has allowed access too. One might point to some sinister aim in this kind of venting, but I imagine this offgassing happened outside their control, bubbling up outside of their containment. This can happen if care isn't taken or some geological factor comes into play which you didn't account for...it is a pretty neat science actually, gives geologists something new to do and map out. Generally speaking, if your venting gasses, your also venting the stuff you are trying to collect, which is undesirable, even more so if it is the gasses your after (and depending on the regional prices, that is usually what they are after, australian deposites are usually pretty low in liquid hydrocarbons, meaning they are usually after gas in the land down under). I just posted a very long winded video on the subject if you wish to learn more details about the environmental and health impacts of fracking and new gas extractions technologies. In the end, it might just be a new hydrocarbon to burn and throw into the atmosphere and cause harm. Butin the short term, it might be a good tool for destroying the coal lobby making way for actual low carbon systems to come online like solar, wind and nuclear. Like all things in life, its complicated with benefits and consequences.

My understanding is that the fracking isn't very easy to control. Basically, they're using pressure to fracture shale, but it's impossible to know exactly how it will fracture. You end up with these little natty gas springs everywhere.

That said, it's important to note that this sort of thing can also occur naturally. That's really been the issue with all of the legal challenges is that you need to demonstrate beyond all doubt that the contamination was the direct result of a fracked well nearby, not just natural geological activity.

@bmacs27 it isn't that hard to control if you understand the deposit, and fracking is just one tool in a belt of different options in horizontal drilling gas extraction. We have been doing it in Texas for the better part of a decade. Most of those horror movies we have seen of people lighting their water on fire has all been in Pennsylvania, so it is something kind of specific to those "ass holes" (mining companies). With that said, I an't the biggest fracking supporter, but if it destabilizes coal, perhaps it isn't all that terrible.
