Why do folks seem to think hydraulic frac’ing of wells is a new thing? Wells have been frac’ed in Oklahoma since the 50’s. The big change is horizontal drilling. These wells require much bigger fracs but still the same process. Water injection has been around since the industry began here as well. Does it play a role in earthquakes along fault lines? Perhaps.
But think about it it, when you are producing a well, you are removing fluids (oil, gas, water) from a producing zone and typically injecting the produced water back down into the ground in a non - producing zone (or perhaps the same zone). Simple material balance says there are changes taking place underground. Removing weight, pressure, and volume from the producing zone leaves open pore space in the rocks and reduces overburden pressure on everything below. Injecting it elsewhere, adds pressure and weight and causes expansion of pore space. This injected volume will take the “path of least resistance” and travel down any natural fractures in the rock that are there. Will/can movement take place causing small earthquakes? Likely.
Not thinking Oklahoma is going to quit producing wells anytime soon so I’m guessing these small earthquakes that are possibly caused by the industry will continue indefinitely.
Same as the earthquakes that occur “naturally” and have nothing to do w/ oil and gas.
Well said. The left can take any word, make it a dirty word, and a good number on our side will take the bait

In What post number did you post the IPCC mean temp “hockey stick” graph?
Besides the link you just posted.
Middle of pg 2 if you have the long page setup.


Anyway, my point was the Standford funded study by the earthfirster liberal pukes that illustrates the "rapid increase " in Oklahoma earthquakes looks very similar to the hockey stick graph the global warming pukes used 20 years ago.

It is a very common liberal tactic to take a small amount of data, (which usually is a load of crap in itself), show a sharp increase in something and use that as a bludgeon to change public policy in a way they want.
