Study Links Swarm of Quakes in Texas to Natural Gas Drilling

So...maybe fracking does cause earthquakes.

There appears to be little doubt about the conclusion that the earthquakes were in fact induced," USGS seismologist Susan Hough, who wasn't part of the study team, said in an email. "There's almost an abundance of smoking guns in this case."

Class II injection wells, are now related to drilling? Or fracking? As opposed to what the article said, which is that this is wastewater injection? is anyone else here aware that wastewater injection ISN'T fracking…but wastewater injection? And has been going on for industrial waste, industrial ag, and produced waters, for more than half a century? I suppose we can't let the facts get in the way, I mean really what fun would THAT be...

The article is saying the wastewater and/or brine being injected is coming from the gas production process.

In order to have a gas production process, you need to drill.

Once you have drilled in this area, in order for the well to be "productive" you then need to frack.

Fracking, by itself, does not cause these earthquakes, but they would not occur if there were no drilling and fracking.

Yes the quakes are primarily caused by injection of brine and wastewater,  and secondarily by the removal of brine from the wells when the gas is produced.  But a layman can be excused of viewing it as one process and calling it fracking.

 In your expert opinion, what are they (as the entire operation) doing wrong.  Bad siting of injection wells or what?

Are you familiar with any component of rock mechanics perhaps?
