Can't drill into a red-hot high-pressure slurry. That's why the millimeter laser that forms it's own casing is being evaluated.

Quaise
Quaise, Inc was founded in 2018 to develop a millimeter-wave drilling system for converting existing power stations to use superdeep geothermal energy. The system repurposes existing gyrotron technology to drill 20 kilometers beneath the surface, where temperatures exceed 400 °C. Wikipedia

Hole in the ozone? It's back and bigger than ever.

Also speaking of the epa after decades of abuse the epa lost their defacto law making power known as "chevron deference" the land mark mistake as a result of chevron v epa, back in like the 1970s. West bi god Virginia vs epa corrected that. So the epa will no longer be able to make up laws that ban something like, oh say a refrigerant or plant food.

I've never seen it specifically mentioned.
For six-months I was involved pulling shallow wells. The thought of lifting 10-miles of drill stem, just to change out a drill bit makes my skin crawl.

Presumably the rod at the top of the rig has to support the weight of the miles of rod that's attached below it? Is there an engineering solution to the problem of supporting an increasingly heavy drill rod?
One could fill the hole to help float some of that weight, but that would only cover about 1/8th of it.
EDIT:
Turns out, things get hot pretty quickly with depth;
Only need to go about 3 miles deep to start hitting boiling temperatures.
Seems like we need more boring.

After the hydrocarbons were extracted from the brine, the remnants would require injection down a second hole for enhanced-recovery, plus, perhaps CO2 injection, working against hydrostatic pressure of an inflated crust undergoing isostatic crush.

I Thank and reload the page and there's another one. 'Celisus'?
