The term hydraulic fracturing — the injection of high-pressure water into shale rock to create fractures that enable trapped gas or oil to flow out — has been part of the language since 1948. It was originally shortened to hydrafrac (1948), but the short-form-of-choice these days is fracking. This feels like a relatively new addition to the lexicon, but it's actually more than 60 years old, with the OED showing a first citation from a 1953 edition of Oil and Gas Journal.
