This isn't fracking. This is the Canadian oilsands.
It's almost worse than fracking. They inject far more fluid into the ground.

Yeah, that's scary; the amount of fluid displaced from sand vs. fractured rock. It's incredible they can keep it stable at all.
ChrisFromIT t1_jdim6j1 wrote
With the oilsands, they aren't injecting fluid into the ground.
The sand/dirt containing the oil is dug out, then goes through a process of extracting the oil from the sand/dirt that involves the usage of water.
garlicroastedpotato t1_jdio1xp wrote
You're wrong. I can see what you're saying, but you're wrong on this. They mine the bitumen in a mine then bring it to a facility where it's processed and one of the end products is slurry wastewater. Since the waste water is a byproduct of bitumen it's technically not pollution to put it from where you got it. This stuff is more toxic than the slurry ponds and more toxic than the tailings ponds.
It's called deepwell disposal and its a cost effective means of getting rid of waste water (that otherwise has no way of getting rid of it). It's not fracking (fracking loosens up material making them easier to extract), it's probably worse.

>You're wrong.
Nope. While you are right that there is a thing called deepwell disposal, it happens in other parts of the oil and gas industry. The byproduct of the oil sands isn't disposed of in deepwell disposals. At least when it comes to the surface mines.
When it comes to them having to extract the oil from the ground, yes, deepwell disposal is done. Because the well is already there for them to use.

It's so flippin' cool to me that we're learning how to make earthquakes.
Do you know if there are any serious plans yet to start deliberately taking preventive measures to head off the Big Ones that we know are inevitable at certain fault lines?

When the US government dumped waste from the production of nerve gas into the ground near Denver, it was the first time that humans were known to have caused an earthquake of this kind. One day in the 1980s, my mother casually brought up the subject as if it weren't a big deal. Rocky Mountain Arsenal is now a wildlife refuge on the property.
Tirannie t1_jdj0is0 wrote
That kind of strip mining is only done on shallow sites. Since most of Alberta’s deposits are deep well, they use thermal in-situ extraction methods (usually either SAG-D or CSS).
Most oil sands sites in Alberta use SAG-D (steam-assisted gravity drainage). They drill two wells on the site, one slightly higher than the other, then inject high-pressure steam into the site to decrease the viscosity of the bitumen, which then gets pushed up the higher well. The bitumen gets processed after that (because we can’t use oil with sand in it), which creates a lot of waste water.
What this article is talking about it the disposal of the waste water after, which is injected into deep well sites. Though I’d be interested to see if there’s more research into “induced seismicity” from the extraction process as well.

The following is provided from the USGS:
>FICTION: You can prevent large earthquakes by making lots of small ones, or by “lubricating” the fault with water.
>Seismologists have observed that for every magnitude 6 earthquake there are about 10 of magnitude 5, 100 of magnitude 4, 1,000 of magnitude 3, and so forth as the events get smaller and smaller. This sounds like a lot of small earthquakes, but there are never enough small ones to eliminate the occasional large event. It would take 32 magnitude 5's, 1000 magnitude 4's, OR 32,000 magnitude 3's to equal the energy of one magnitude 6 event. So, even though we always record many more small events than large ones, there are far too few to eliminate the need for the occasional large earthquake.
>As for “lubricating” faults with water or some other substance, if anything, this would have the opposite effect. Injecting high-pressure fluids deep into the ground is known to be able to trigger earthquakes—to cause them to occur sooner than would have been the case without the injection. This would be a dangerous pursuit in any populated area, as one might trigger a damaging earthquake.

The issue is that there is an misunderstanding of what is happening and location.
Based on u/garlicroastedpotato first comment of this
>This isn't fracking. This is the Canadian oilsands.
He is very likely referring to the open pit mining/surface mines of the oilsands. It is pretty much what everyone refers to when they say the oil sands.
The article is talking about the oil sands formation. It is actually fairly large, it goes so far south that the oil fields in Montana and North Dakota are part of that oil sands formation. To get access to the oil in that formation, if you are not doing open pit mining you are pretty much doing drilling which is part of the process of fracking. On top of that Fracking and Steam-assisted gravity drainage is very similar in nature.
And considering u/garlicroastedpotato said it isn't fracking in his comments, he has to be referring to the open pit mining commonly referred to as the Canadian oilsands.
And if you look at the article, the earthquake is around the the Peace River oil sands deposit. Very far away from the open pit mines.
Ergo, u/garlicroastedpotato is both right and wrong. He is right in what is happening, but wrong terms and locations. And because he used the wrong terms and location, he is overall wrong.

Not many seismologists get geologist accreditation because it's not really in the same field, and because certified geologists often deal more with industry/resources than research.

I stull suspect contamination to groundwater is going to be the larger issue in the long run.
Yes, If the wells are dug correctly and don't get damaged, there is a low chance of contamination. The problem is that the wells don't always get dug correctly, and even then damage is still possible.

Less wild than you're probably imagining.
It's more akin to lubrication, really. The potential energy for the quake was already built up; the injected liquid just gets things moving.
It's roughly analogous to a match starting a forest fire or a yell causing an avalanche.

The problem is also that you can't necessarily control the magnitude of your induced earthquake. There would always be a chance that trying to trigger a bunch of M4's would accidentally get you an unexpected M5 or M6, and it's likely that the chance is unacceptably high given the number of quakes you have to induce to release enough energy for preventing the bigger ones.

They occurred in Oklahoma to a much greater degree, and the Oklahoma Geological Survey (the state level USGS) published information demonstrating it was the fault of fracking.
If course, that was after oil companies (specifically Harold Hamm) and the University of Oklahoman's President, David Boren, attempted to stop them from publishing.
