Wait. Am I getting this right? They want to inject high-pressure steam and chemicals into a massive underground natural gas reservoir. Then set off a big fire + explosion.
Surely, nothing can go wrong.
It’s called in situ combustion and apparently it’s a well established practice in the petroleum industry: https://glossary.slb.com/en/terms/i/in-situ_combustion
So is coal extraction. How long has that coal fire burned under that town? 60 years?
You can read all about the Centralia mine fire here. ISC for oil extraction, as referenced by the paper, is not applicable to coal mining.
You miss their point
I do. I hope they will explain.
To spell it out for you, Just because something is well established in the industry does not make it good.
I never said it was good. I said it was a well established practice in response to @fubarx@lemmy.ml who seemed surprised that anyone would even consider it. I was surprised to learn about it as well, but it makes sense to use the oil or gas in the deposit to directly help fuel the process.

The alternatives are the status quo or severely restricting natural gas extraction. I won’t say the latter isn’t doable, especially if we can ramp up nuclear power capacity, but there’s a lot of baggage there. We should welcome a solution that effectively makes natural gas an emissions-free resource.

I don’t understand what you mean. As described in the article, the process leaves the CO trapped in the ground.

Not sure what direction to point you in. Gas storage in geological formations has been successfully practiced in the helium and natural gas industries for a while. Subterranean storage of carbon dioxide has also been successfully demonstrated. Apparently, there’s a big gas field being used for this purpose off the coast of Norway since 1996.

Yes because igniting fires underground is a GREAT idea!
Centralia,PA would like a word…
