Site of next injection earthquake?
I have some hope for this site in Texas (with the fresh red earthquake). It's just down the megathrust from OK, so it's a good site. People don't realize that it is a risky thing to drill an injection well when you don't know a thing about the Precambrian basement. Between the megathrusts you have very high stresses (like the Niagara Tunnel!), and you can't inject a drop. Many such wells have been abandoned. But if you hit the active hanging wall of the megathrust, water goes in like a sieve. Soon, many more injection wells are joining you for the party.
Just like Arkansas, OK and the rest, I have great faith that they will continue to inject until they get a big earthquake. Since this is in the middle of nowhere, I hope they break the record!
