The majority of all wells will get a hydraulic fracturing treatment sometime in the life. Too many pretend that only shale play wells are hydraulically fractured.
By some estimates, up to 90% of today’s producing wells were stimulated by fracking.

I agree. Just noting that the way language works is that words change their meaning based on the way they are commonly used.
I could be wrong, but from what I can see, the term “fracking” is presently used primarily to reference the complex of modern methods developed over the last 10 years or so.
