We're students blogging research on "Fracking in the Oil and Gas Industry," Spring 2011 in Prof. Tom O'Donnell's OSU (The Ohio State) course on Global Oil and Geopolitics (501 Social Studies/Science/Economics,Class #28147).
Great article. It says that fracking was first successfully performed in 1949, and that some estimates indicate that 60% of all wells drilled today use the process. I had no idea that fracking was so old or so widespread, and the fact that it is makes me wonder why it has suddenly grown so controversial.Is the fracking taking place in more sensitive locations? Are they using different, more harmful chemicals? Or has it always been this controversial and I've just never noticed?
I think what's new about fracking is that it's being used to get natural gas, but I really need to do some more work on that.
