Fracking in Lancashire suspended following earthquake

Operations have been suspended at the UK's only fracking site following an earthquake - just 11 days after it was given the green light.

Energy firm Cuadrilla said it would halt fracking at the Lancashire site for 18 hours after a tremor of 0.8 magnitude was recorded.

Drilling for shale gas at Preston New Road, Little Plumpton, started on 15 October after a legal challenge failed.

A Cuadrilla spokesman said the "tiny movements" could not be felt.

Not a 'biggy' by any stretch of the imagination but something that will be seized upon by those who are opposed to fracking no doubt.

2004 an oil rig by Taylor Energy was shreddered by hurricane Ivan. Since then, over three dozen leaks showed up at aroiund dwells that were drilled by this platform, and all efforts to seal them off again, mostly failed, less than one third of them got sealed off for sure, the others still leak as always. Since then, in these 14 years, every day around 100 thousand litres of crude oil leak into the Golf of Mexico, which makes this havary more damaging to the environment than the Deepwater Horizon desaster, 20 km offshore the Mississippi delta ending in the Gulf.

The media do not report, almost nobody knows about it, nobody cares, I heard about it just days ago for the first time ever.

And you guys in Britain worry about a little earthquake?

Not me Sky.

The UK has hundreds of earthquakes every week and most are never noticed.

I am against fracking its just a poor attempt to say this is needed and its good for you, just watch your fuel bills come down.

YEA RIGHT THAT OLD CHESTNUT OF A LIE.

Second 0.8 tremor in 24 hours.

Fracking is a two-sided sword. Usually this is only done when the oil/gas will not flow freely anymore (often when the oil well is getting exhausted, pressure drop etc.), it can be used for oil and gas reservoirs.

Those reservoirs are not big caves, but the stuff we want is distributed in cracks and geologic faults, gas like oil. The reservoir is located in stone or sediment, with water, oil and gas filling up the spaces between e.g. sand corns or in smallish cracks. You have a porosity, and a permeability.
To get more out you try to increase the permeability in the reservoir.

To squeeze more out you use what is called hydraulic fracking, you press a fluid down the production pipe, causing the sediment to be "blown up", and widen cracks and pore space, to make the rests of hydrocarbons flow freely again.
The fluid used is mostly loaded with chemical drag reducers like detergents, but also with specially formed plastic, stone or ceramic particles, to keep those opened cracks open, when the remaining hydrocarbons get out. Some of this stuff is toxic.

So the geologic layers being pumped up increase in volume, and decrease again, which of course has an impact on the surface since the whole reservoir structure is "inhaling" and "exhaling" in a way.
Further problems are the chemicals used because regardless how careful you are, a lot of this stuff cannot be regained at the surface, additionally the production pipes of older wells can be badly corroded, and leaking.
So you also lose some of the stuff to groundwater horizons. I guess you can imagine what can happen next, from gas to all kinds of chemical pollution, in the drinking water.

The whole procedure is also expensive, financially.

We have had several cascade earthquakes of signififcant strength in recent years in the Volcanic Eiffel region over here, their frequency is quite high and growing still, and to geologists it is clear that it is magmatic activity deep underground. The depth is the reason why on the surface is only felt little of it, but it also means the threat potential is quite high. Somethign is loading up down there. There is growing concern that a major eruption could take place again anytime in the next 30-300 years, but nobody wants to care for it, nobody wants to pay attention to it. Since the whole Eiffel region is one giant volcano, that pretty much could mean game over for Germany as an integrated state and economic actor.

THAT are concerns, dear Brits...!

After further study, it was found that Britain can no longer support the weight of Jim's diecast collection.

The report was published in the Journal of Geophysical Research: Solid Earth. It found that the 6.0 Napa quake may be tied to a dip in groundwater levels that happens during summer months.

Napa County’s disaster trifecta of earthquake, storms and fire might end up costing county government $80 million to $90 million, though insurance and federal and state reimbursements will remove much of the financial sting.
