All companies, at all location, are required to have on site the MSDS for every chemical being used on site. So in every location, there is access to what chemicals are being used, but not the exact amounts.
Some states, like Texas, have required that companies have a public online database where individuals can access what chemicals are being used for hydraulic fracturing.
Railroad Commissioners Adopt One of Nation's Most Comprehensive Hydraulic Fracturing Chemical Disclosure Requirements

That disclosure must be made at a web site the industry had already started where multiple companies at many different locations had already started listing those chemical to put the public more at ease.
At Fracfocus.org, you can look up individual wells just by a geographic map. However, it is not yet used by everyone and is still a growing database.
Other major companies that actually perform the hydraulic fracturing (not the oil company, but the company hired for that stage of the well completion) have started their own online database for people to search. For example, you can search what Haliburton has used in some different areas.

I don't know if a mere 50 or 60 year track record is good enough for a process that could conceivably render an area uninhabitable in 100 year's time....
100 year time??? Do you understand that after a well is hydraulic fractured, that fluid removed so the well can now flow out the cracks made during fracturing? Not every drop will initially come out, but nearly all does. However, the flowing gas/oil is pushing that remaining hydraulic fluid back up the well. It isn't going to stay down there. The pressure of the reservoir is pushing that fluid back out. It is not going to stay down there and spread out; there field pressures are pushing it the other direction.
Thanks. Exactly the kind of info I was looking for.
“Do you understand that after a well is hydraulic fractured, that fluid removed so the well can now flow out the cracks made during fracturing?”
No, I did not know that. Again. thanks.
If these folks were truly concerned about the environment they would be PROMOTING drilling and mining in the U.S.A. where we have so many rules and regulations regarding environmental and worker’s safety. But by shutting down activities here it shoves it off to places like China, Indonesia and Nigeria where neither the worker or the environment gets a second look.
I was at a mine in Indonesia and they had something in the company news letter about their highly rated safety rating. I was there for only three months and there were two deaths!
