Er, sorry Ralph, but your link is to the report on the Bowland Shale. This is a Carboniferous formation underlying large parts of northern England but Balcombe is in Sussex and the rocks in question there are Jurassic.Ralph wrote:and what it contains of interest....biffvernon wrote:For the geologically inclined here's a good description of what's underneath Balcombe:

Great, that means it will be desolate countryside, so we can frack till the cows come home. Or is it till the chickens come home to roost? As they surely will.biffvernon wrote: Er, sorry Ralph, but your link is to the report on the Bowland Shale.

Oh please...one shale looks just like another...and apparently they contain thousands of TCF of natural gas. The hoopla over this stuff is quite extensive, and unless the Jurassic shales are lacustrine or never reached a thermal maturity window, it is just a matter of time before they are awarded their own TCFs of resource which will then be fought over just like all the rest.biffvernon wrote:Er, sorry Ralph, but your link is to the report on the Bowland Shale.

To you maybe! Of the order of one thousand according to the BGS.Ralph wrote: one shale looks just like another...and apparently they contain thousands of TCF of natural gas.
That's a bit disingenuous.biffvernon wrote:Yep, that's what fracking looks like.
Well, I'd agree about the UK. As for the US, I'd need to see a picture to compare it to the Chinese one.clv101 wrote:It looks the same in the US and the US is about as 'west' as you get. If the UK isn't able to employ high density drilling like this, and in the US, then a lot of the other comparisons like production, cost etc aren't straight forward.
It certainly doesn't look good. However, I would want to know the scales use in the Chinese one versus the yank one. If they are widely differing scales, then they are not as comparable as they might appear.clv101 wrote:See page six of this thread for some photos from the US.
I understand the approach taken. But, the problem with it is that, in the end, those localised issues end up being proven to be unfounded (or far less severe) as the industry marches forward, This, in turn, discredits the critics who employed those localised concerns as the public focus of their critique. Then, we end up with a situation where no-one is prepared to listen to any critique.clv101 wrote:It is an interesting debate. I think the real threat associated with fracking is the additional CO2 emissions associated with adding more fossil fuel resource to the ledger of recoverable reserves.
I'm not actually all that worried about the local issues, issues which I believe can largely be mitigated/controlled, as well as any other industrial process anyway.
However - it's certainly clear that the threat of additional CO2 won't bring middle England out in protest! The issues that motivate regular folk are local noise, local pollution etc. If the activists had focused on the CO2, they wouldn't have anywhere near as much public support as they have now. Sadly, the (frankly ridiculous) threat of earthquakes has proved to be a more powerful motivator than additional CO2 emissions.
