Minor Quakes In the UK Likely Caused By Fracking

Stirling Newberry writes "Non-conventional extraction of hydrocarbons is the next wave of production, including natural gas and oil – at least according to its advocates. One of the most controversial of the technologies being used is hydraulic fracture drilling, or 'fracking.' Energy companies have been gobbling up Google ad words to push the view that the technology is 'proven' and 'safe,' while stories about the damage continue to surface. Adding to the debate are two small tremors in the UK — below 3.0, so very small – that were quite likely the result of fracking there. Because the drilling cracks were shallow, this raises concerns that deeper cracks near more geologically active areas might lead to quakes that could cause serious damage."

Not to mention its potential impact on local groundwater:

My brother in law works on a rig. Last month his crew got a hammerbit stuck in the hole. They pumped hundreds of barrels of "soap" and water into the hole to try to free it. This well was communicating with others which started to leak this fluid. So now you have gas wells that are 50 years old pumping lubricating fluid instead of gas. Since that is another company, they will likely get sued. Had it been a water well they homeowner might not have the resources to do that. They ended up using explosives to free the pipe but they lost the bit and a few collars. The rig started to sink due to the vast amount of fluid pumped into the ground. How much environmental study was involved in all that?

This isn't what I had in mind when I asked for 'firewater'

The movie Gas Land has been discredited and this particular water source had Nat gas in it BEFORE fracking began. They are called hissing wells; water wells that are also souces of nat gas. If anything Fracking will improve the water source since it is removing the nat gas. Peddle your propaganda elsewhere.

Yeah right. Google for affirming gasland. I read through some of the arguments from each side, and it looks like a canonical example of astroturffing by well funding public relations firms.

Even with a major earthquake

[koan]

Even with a major earthquake occurring because of "fracking" it's a non-issue compared to the damage done to the water table by the chemicals used in the process, toxic for centuries afterwards.

Gas reserves are far below water tables in complete different strata...five thousand to 20,000 feet, far , far deeper than any aquifer.

But you keep drinking that Kool Aid.

Yea, 'cause you don't have to drill through that first, and there's no chance that raising the pressure below could force things just under the water table up into it.

It might not be as bad as 'the sky is falling' folks claim, but it isn't good either.

I've never understood why we are so damn eager to extract more substances from the Earth.

It's because capitalism is a one way process; it's not a system.(*)

It takes a finite resource (such as oil reserves, or coal, or iron) which belongs to all of us (we all share one planet) and assigns it to an owner (generally via opaque means rooted in corruption, even in the US). This owner then exploits it to produce a profit. Some of which might come back to us but most of which is shared out amongst an elite as part of their ongoing petty powergames. This is the same elite who have shaped our society for several hundred years now to believe that making profit is an unquestionable good and that growth is something that can happen infinitely.

The damn eagerness is just the effect of long-term greed; and while profit is king this process will continue until all the natural resources are depleted, and the human population falls or otherwise adapts to the level which renewable supplies can accommodate.

But I doubt if many come here for a lecture on Marxism.

(*) Economics, on the other hand, IS a system.
- Capitalism is the dominant processes that currently operates in the economic system. Without a counterprocess to resupply it, however, it will inevitably run down as it's resources run out.
