In my primitive petroleum engineering mind, you don't produce any oil & gas from a shale formation without fracturing it in the first place. Trying to compare hypothetical water cuts before and after fracking is really meaningless. Without the combination of long horizontal laterals into shales and fracturing each well, there's no renaissance of US oil & gas production that we've seen in the Permian or anywhere else. @Armybrat's chart is interesting. I didn't plot out the number of earthquakes over time, but they don't seem to be increasing in frequency. Is this quake related to/caused by water injection secondary to hydraulic fracturing? Who knows? Does it matter? Honest questions here. Geopolitical forces have most certainly changed as a result of the shale production revolution, aided by hydraulic fracturing.
I happened to be on a wellsite south of Odessa at the time of the quake, and did not perceive it. Was in Mentone the next day. I didn't see any widespread damage, at least related to earthquakes. Mentone itself is kind of an ongoing disaster.
Old chart, but shows the impact of fracking in Permian:
