Read the article carefully. Its generally not the fracking that causes earthquakes...its (maybe) injection wells. And most injection wells in Oklahoma dispose of fluids from conventional wells.
Ergo, when the media scream ‘fracking causes earthquakes’, they are not being honest.
What (may) have happened is that an uptick in oil production in Oklahoma due to a period of high oil prices caused more injection well use. That’s what ‘magically’ made OK an earthquake zone - not fracking my hair’s on fire fracking.
This is 100% correct. It’s not fracking that’s causing the earthquakes.
There are literally no earthquakes in Colorado, Wyoming, North Dakota, anywhere else that fracking is occurring.
The cause of all of it is the high pressure injection wells in the flint, limestone, and sandstone in Kansas, Oklahoma, and Texas.
Most of these wells have a pressure of 1/2 psi per foot of depth, if you have a well that’s 4000 feet down, that’s 2000 psi fracturing this type of rock and causing the earthquakes.
But thanks to our good ol buddies at the EPA, (/s)
these wells are the only method they let these companies dispose of the brine used in these type of drilling.
