Fracking in Lancashire suspended following earthquake

Catfish · 10-27-18, 11:10 AM

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.

WE GOT THE BRICKS TO GO AROUND

; I HAD LOST MY CHIMNEY IN THE 5.8 QUAKE OF '99 WHICH 'EPICENTERED 500 YARDS FROM MY HOUSE AND GOT A GOVERNMENT GRANT FOR A NON-BRICK 'TO CODE' MODERN REPLACEMENT(METAL TUBE AND STUCCO); SO NO HARM IN THE 2014 QUAKE...MOST OF THE SERIOUS INJURIES AND DEATHS COME FROM THE FIREPLACE & CHIMNEY BRICKS FLYING DURING THE TREMORS

HOWEVER I DO LIKE THE CHEAP WINE SALES THAT FOLLOW:

AND THE KIDS 'MAKE DO' WITH OPPORTUNITY AS WELL

In before Reece, is it true the earth moves for you when having hubba hubba during a earthquake?

WHA!!!!.... U NEED MORE ARICEPT LAD; THIS WAS ALREADY DISCUSSED AT GREAT LENGTH IN THE BILGE http://www.subsim.com/radioroom/showpost.php?p=2239154&postcount=329.. .WITH APOLOGIES TO EARNEST HEMINGWAY'S FOR WHOM THE BELL TOLLS:“But did thee feel the earth move?”
