Does drilling cause earthquakes?

[Mott the Hoople]

I frankly cannot see a mechanism to cause liquifaction to occur, you would need earthquakes of at least magnitude 7 and above for that to happen. I wouldn't advocate injecting shitloads of water into the San Andreas fault but then I assume that nobody is stupid enough to even try. One thing I would say though is that a lot of the regulatory powers are at state level, I think they should all be brought under federal control as that is the only way to ensure best practice throughout the USA.

I tend to agree. Geological surveys can be required as part of the permit requirements for fracking that it be determined with BADT that no drilling be permitted in the region of faults.

If people like Rune were around in the early days of flying machines, he would have had those banned as well.

Explain to me how the hell you can use HF with water, that would result in a hugely exothermic reaction probably resulting in an explosion. It also baffles me why you would want to use aromatic hydrocarbons such as benzene or toluene.

I could probably dig you up a link on that but trust me. They do use HF in fracking fluids. I've seen the MSDS's and I've reviewed the analytical to obtain approvals from permitted disposal facilities to treat the stuff. As for the aromatics, I don't know if they are used in the front end of fracking but they are a component of natural gas and it would be my guess that that is why they are present in produced waters. Having reviewed the analytical of produced waters, I've seen both of these aromitics present. As for how to use HF...hell all mineral acids are exothermic when mixed with water. The answer to your question is that they are premixed. They just don't pour reagent grade HF down a well casing.

 

[Mott the Hoople]

Totally agree apart from your spelling of aluminium!!

LOL

 

[Mott the Hoople]

In the UK wells are all triple lined, that is best practice and it is surely easy enough to specify the same in the US. What seems to be happening is that the whole industry is being maligned because of one or two cowboys in the early days.

Yea, that's something the PIA has to consider. I know my thinking about increased regulation is NOT, and I mean really IS NOT, what they want to hear. They have to either consider that or consider that the poor public plublicity may lead to greater public pressure for banning that may be heeded by public officials.

I have done a little research and it seems that diluted HF is indeed used sometimes, I may be wrong here but I believe its molarity is less than is present in the stomach which is typically around 0.15M maybe you know more on the subject? I guess that there may be some traces of aromatics coming back from the well but I can't imagine that we are talking vast quantities. I suspect it is trace amounts which show up in the IR and UV spectroscopy results.

I can recall any MSDS's for any specific fracking products (I see far to many MSDS's to remember them) but tyipcal analytical for returned waters have Flourine and/or Chlorine in the 0.01 to 0.5% w/v range.

What research did you need to do? It was listed on the DoE chart you pretended to link to earlier. In fact, it's the first fucking item listed. Of course, the chart you actually posted from the lovely people at the American Petroleum Institute didn't list it.

Damo it's too late for winky faces. After the last debacle Grind has cemented his place as my favorite mod, ever, and he can do no wrong in my book putting him up there with Cawacko. You are a distant second and Billy doesn't even place, sorry!

I have to say that my opinion of you has really gone down, I have already told you that you cannot copy from the pdf on the DoE website. I hadn't realised that you were subject to the same hysteria that seems to affect so many when talking about the subject. It seems to me that what you are most pissed off about is that your gotcha fell flat on its face. As to the first item it says hydrochloric (HCl) or muriatic acid it doesn't mention hydrofluoric acid (HF). Muriatic acid is an archaic name for hydrochloric acid. I suspect that truth is that HF is only used as a last resort if HCl proves ineffective.

Water table contamination does occur from fracking. Mainly from faulty well casings that leak. That can easily be managed by specifying well casing construction (and that may all ready be the case) and requiring leak detection devices and inspections (again, as far as I know those could all ready be requirements). Also water table contamination has occured from storing return or produced water in open pits and other substandard methods that lead to contamination.

Bingo! The return water is a major problem.

See this is why I have a low opinion of you, Mott didn't say that at all. He said that it could be a problem so you instantly grabbed that and decided it was a major problem. You are not really interested in the facts, you have already made up your mind and will only filter info that you think confirms your ill informed views.

Flat out wrong.
I have been pointing to return water as being a major problem for days. Read my posts in your fracking thread.

End of discussion right here. The fact is that while only 11% of the fracking fluids return during the creation of the well, ALL of the fluids will return to the surface during the life of the well.

Since you are clearly unaware of the actual science involved in fracking, your opinion is of less than little consequence.

There is a massive shortage of regulations here shill. Once the gas company declares the well to be in production, the fracking fluids become termed "produced water". 500 millions gallons of water and chemical unaccounted for.

From your link:

New water treatment
technologies and new applications of existing technologies are being developed and used to treat
shale gas produced water for reuse in a variety of applications. This allows shale gas-associated
produced water to be viewed as a potential resource in its own right.

You have to be kidding. Next time you give me something to read, read it yourself first.

And harm those who use water for drinking.

Mott, what of the fluids which return out of the well? You know, the so called produced water?

Can you prove that? According to Dr. Ingraffia, Proff. of Fracture Engineering at Cornell, "of course it all comes back out. Where else would it go?"

But that isn't what is happening now, is it Mott? In fact the so called "producer water" is in fact the water/chemical mix which was injected during the fracturing process isn't it?
And due to the exemptions from enviromental laws, it isn't being treated at all is it? Furthermore (and you should already know this) public water treatment plants are incapable of processing said water, since the contaminents are so far removed from the design parameters of the treatment plants, right?

Cite? Never mind the fact that (according to you at least) the water is locked up thoudands of feet below the surface?

Mott? A little more "clock cleaning"needed.

OH ok, I have better things to do, I need to talk to my niece on Skype, she is trying to find another teaching job in Bangkok. Frankly you can do what you like over there, just so long as you don't export your bullshit over here.

Since I knew you wouldn't bother to verify your ineptness, I linked to my comments on produced water, above.

All 9 of them, not counting 3 videos I posted also detailing return water disasters.

Thank you Rune...damn...I live in PA, not known to be a geologically active area and we've had earthquakes and guess what...it happened after fracking started. This has been noticed in many areas...I won't even go into how unsafe pumping the waste into the ground is. How incredibly stupid are we?

You are incredibly stupid. That is indisputable. Glad we agree on something

[Guns Guns Guns]

Geologists say recent earthquakes in Colorado and elsewhere were induced by a drilling procedure to dispose of wastewater, and regulators in Colorado have started to look for seismic risk in permit reviews...
