You boys keep on keeping on. We need you, despite what the orange Kool-Aid says!

Not rocket science. You bust the lime stone into sand so the gas can pass through it better, The earths crust on top is now setting on jello and can move as it wants. I thought the government put a stop to fracking as a result of the Fox Creek incidents.

Thanks for the education.

Not exactly, and not exactly.
I won't touch on the first points as everyone nowadays has access to Google.
To answer your question, the AER shut down frac-ing around Fox until it could be determined if there were imminent risks of setting off another sizable quake. Once it was determined that the odds were slim, activity was allowed to commence. Albeit much more closely watched for the first 30 days or so.

Spoken as a true expert in the field.

Fracking can and will cause seismic activity, including earthquakes. That's a fact. Anyone who will tell you otherwise is just burring their head in the sand and doesn't want to deal with the real world.

It can, and does, effect ground water and/or water levels - another inconvenient truth.

The reality HOWEVER is that it rarely leads to seismic events of this size and has NEVER been attributed to major property damage or loss of life.

Keep on Keepin' on boys .......... but let's not deny for the sake of denial and look like a bunch of senseless fools.

I look at it this way ........slaughtering a pig for the freezer isn't pleasant to look at - but the boys need to eat ...... so slay away

Look up DANGER CATS ...........pounding mother earth ....... a good laugh ..... I did not post the link because I think it contravene's this site's policies - but it's pretty funny (and spot on).

X2. Lube up a shallow fault and you will get a shallow localized earthquake as any tension is released. Companies learn what triggers such quakes and mitigate operations to prevent.

This looks fairly close to definitive.

And when you say "possibly has absolutely zero to do with", it's the same thing as saying "possibly has absolutely everything to do with".
Food for thought...

Well considering the earths crust is 20 to 30 miles thick, that is impressive.
I'm guessing your profession isn't rocket science?

I agree with this 100%
To deny reality takes away all credibility.
We're beyond wondering "if", that's already been proven several times.

Everyone in the oilfield is going to have to come to terms with that.

I personally see frac-ing going away all together one day, but for more reasons than just the tremors.
And I'm not anti-frac, I just see it for what it is...a process that has many pros and many cons. Unfortunately the cons are coming to light more and more.

That was a pretty cool event. The icequake at Lac Ste. Anne was due to the significant warming (about 30°C) that occurred during the 24 hours that preceded the 'quake. This caused rapid thermal expansion of the ice (of perhaps meters), which overwhelmed the strength of the frozen near-shore soils.

A few other key factors:

Snow cover on the lake was either absent or very thin, and thus provided very little thermal insulation against the above-mentioned warming.

The preceding late summer and fall were rainier than normal, which had two effects: 1. lake levels at Lac Ste. Anne were a bit higher than normal, so the force from the expanding ice pushed on soils higher up the bank than normal. 2. the soils were contained more moisture than normal, which made them stronger than normal when frozen - and so better transmitted the force from the expanding lake ice. This is why so many structures were damaged.

So, the icequakes and resulting damage seem to have been due to a pretty particular combination of conditions. Cool stuff.

*In addition to Lac Ste. Anne, icequakes were also felt that night at Gull, Wabamun, and Pigeon lakes.

Well said ,im in the field and if you think this is not happing because of fracking .

He was obviously not frac-ing well # 0489617.
That crew wasn't laughing

Contained in the order is reference to a call from Vesta advising their fracking operation at the site was responsible for the event.
Did I read that right?

My understanding is that Vesta’s seismometers were the first to register the earthquake.

My gut suggests they drilled horizontally across a fault and triggered it. 3D Seismic data over area will likely be used to reduce risk in the future.

I was literally sitting on the bumper of a frac pump when I typed that haha.

We have a winner.

[Mr.F]

I like the Fracking debate, nuanced opinions are always better than absolutes. Research, data, and investigations are are worthwhile endeavours.

I think this needs to be clarified, it was not caused by the drilling, it was caused by the frac.
I'm sure that's what you meant though...
