Does anybody know the name and/or formula of the chemicals they inject into the ground when hydrofracking?

Asking it here because there is a resident expert on this board.

The cocktail they use is confidential information. Only the drilling folks know which toxic blend to inject. Various forms of benzenes and
other contaminents. There are many reports showing the chemicals found after drilling has started.
I am not the resident expert. Just feel fracking is shortsighted greed. Water is way too important to risk for money.

I think they should not be using proprietary blends of poison chemicals, they should have to declare the chemicals so we can regulate them. I think they can frack with plain water.

Natural gas isn't the greatest thing anyway. Can't use it in cars, imagine your gas tank has 6000 psi in it.

A natural gas vehicle or NGV is an alternative fuel vehicle that uses compressed natural gas (CNG) or liquefied natural gas (LNG) as a cleaner alternative to other fossil fuels. Worldwide, there were 14.8 million natural gas vehicles by 2011

in my opinion, its all about what level of risk we can accept. Generally speaking, the leaking rusty 30 year old gasoline storage tank at your local qwik-e-mart is doing a hell of a lot more damage to our groundwater than frack fluid in a properly cased well. Most of the backlash against fracking originates from piss poor early fracking done without regulation. I'm not an expert, but I have informed myself enough that I think mining our own resources (if done safely) is much better than the alternatives.

Marty,
Glad you weighed in...
Have you read the USGS studies that support the hypothesis that fracking has lead to numerous injection-induced earthquakes in the mid-west? If you haven't you, as a USGS employee, might appreciate them.
That, coupled with the regular contamination of groundwater by the fracking slurry and the retaining pools of the byproducts tells me that fracking is far to risky a technique to pursue.

zip-

I'll take your tone and wash it down with a beer. I have seen that study. linked from here:
http://www.usgs.gov/blogs/features/usgs ... rthquakes/

Quote:
USGS’s studies suggest that the actual hydraulic fracturing process is only very rarely the direct cause of felt earthquakes. While hydraulic fracturing works by making thousands of extremely small “microearthquakes,” they are, with just a few exceptions, too small to be felt; none have been large enough to cause structural damage.

also:
Quote:
of the tens of thousands of deep injection wells in use by the energy industry across the United States, only about eight locations have experienced injection-induced earthquakes, most too weak to feel and none causing significant damage.

source(more info here, written by penn state prof): http://www.nytimes.com/2013/03/14/opinion/global/the-facts-on-fracking.html?pagewanted=2

It's the injection of water that's apparently causing them, not fracking itself. Proper fracking fluid disposal is key and of most importance--agreed. With modern techniques, and proper oversight and regulation, it can be done safely. I have talked to groundwater specialists in my office who've actual testified in court as experts. I'm not representing the agency I work for when I say any of this stuff by the way. I'm by no means saying there haven't been bad things that have happened as a result of poor management and bad practice with regards to fracking--that would be silly.

Natural gas isn't going to go away any time soon. Energy independence is what we should be striving towards. I just think there are many equally "risky" issues at hand both domestic and overseas to be not putting our efforts behind safe fracking. There are tons of things polluting our groundwater--We pump sewage into our surface water, pharmaceutical companies dump chemicals into rivers, we have leaking fuel storage tanks, PCB's in our rivers. I mean we've done a lot of damage. We learn from these things and improve them with technological innovation, good science and regulation. Sorry for the rant, I'm gonna check out on this topic now. :geek:

I hate when I ask a question and people answer a different question. I asked if it were possible to frack with plain water or regulate the chemicals so they don't use poisonous ones, and somebody answers that fracking is bad because they use a poison chemical slurry. Anybody know the answer to my question? Is it possible to frack without poison chemicals?

Greg did answer your initial question-- the concoction is 'confidential' company secrets, and I think they vary it depending on the subsurface geology. you can frack with plain water (and most of the solution is plain water), but my understanding is that its not as effective at breaking up shale. Working on regulating the concoction is what is happening via EPA. Key to the process is disposing of the fluid once its pumped back to the surface.

When they were drilling my water well they had to hydrofrack to open the veins in the rock. They obviously used nothing but water because it's a water well for household water, but it worked just fine.
