It may be used in fracks (news to me), but I know it isn’t used in drilling. Can you provide links to your information? I’m always willing to learn more. I’d rather get it right.
We’ve never used it on a frac job and I can’t think of any reason why one would.
I checked several of the articles and they do mention acetone but they are all of the anti fracking type. Nothing from a source not involved in trying to stop fracking. From what I read the oil companies don’t disclose what they use in their fracking fluid. The EPA just issued a new ruling that says the drillers will have to disclose that information after a well is fracked so I guess we will all know soon enough.
