What did the Soviets discover in the Kola Superdeep well at a depth of 12,262 meters?

We know so little about the structure of the Earth. For example, our planet is not fully spherical, as it slightly flattens when rotating. Therefore, its equatorial diameter (12.754 km) is 43 km larger than the polar one (12.711 km). Our planet is the densest celestial body in the solar system, followed by Mercury among other planets. Different layers of our planet's core, crust, and mantle rotate at different speeds relative to each other. Oxygen makes up about 50% of the entire mass of the earth's crust, which is found in bound form in almost all minerals. About 25% of the crust is silicon, and the remaining 25% is everything else.
The continental crust is on average 35-45 km thick but it can reach 75 km under mountain ranges. The matter density in the center of the Earth's core reaches 12.5 tons per 1 m³, and the pressure there is about 3.7 million atmospheres.
Humanity has dived deep into oceans, flown to the moon, and even sent its robotic explorers to Mars. We have studied the surface of the Earth quite well, but as always the most interesting thing lies deep inside. And although these depths are literally under our feet, we know little more about them, if not less, than about the deepest space. A whole "expedition" is needed to look even a little into the earth's crust, just like flying to the moon. And there have been such projects that brought some amazing data.
Well, it's time to find out what lies deep down in the ground. Is there life out there? And what interesting things have already been found there?
Today we'll look at three of the most interesting ultra-deep wells that became one of the first projects exploring extreme depths of the earth's crust.
What was found in the deepest wells?

Hi. Do you think there's anything interesting out there?

[totalbliss]

My ex-wife's dark, black heart is somewhere deep down there. Please return it to her if you come across it.

I once dug a 6ft hole in my backyard, so I can understand these challenges.

I’ve worked in the oilpatch in Western Alberta for 25 years and have a bit of an infatuation with Deep Wells and the challenges associated with them. I’ve been aware of both the Kola & Bertha Rogers wells for 20 odd years now and despite much research, this vid has the best & most images of the Kola drilling operation. I had never heard of the Swedish well so thanks for the tip. The temperatures we were encountering around here at 3000-3800 meters were in the 100-130 degrees Celsius range.

I'll save you 20 minutes: Dirt, rock, some water, but mostly nothing

Exploring deep holes. Man's fascination since the beginning.

[mattcheshireify]

12.75km? I think I’ll walk around the planet tomorrow.
Might want to check the decimal place there..

[captainzeppos]

Someday they'll discover a sleeping Balrog down there and we'll all quickly come to regret this.

[alexmitchell]

Came for a wild Soviet story. Stayed for the fantastic nap that this video facilitated.

As an exploration driller who regularly drills to about 1km deep I’ve always been fascinated about drilling much deeper. It is already a difficult job drilling beyond a K and I have no idea how the drillers were able to go so deep and keep the equipment working.

Everyone knows if you dig deep enough, you come out in China feet first.

[maraxussrafhael]

Well, another wonderful channel I've discovered around here.

[nicholasm]

My favorite parts of the video are where they explain exactly what the earth's makeup is and then say everything we thought was true about the earth's interior isn't.

i live near the appalachian mountains at an elevation near 300 meters. i had a surprise when we drilled a deep well and at a depth of 80 meters what was dredged up was sea shells.

[wmgthilgen]

The one and only thing, though they didn't actual see it. Was the fact that at the distance they bored down to was limited by the constant melting of the drill bit. They utilzied various materal's and regardlessly, none of them were able to cause the bore hole to go any deeper, when they basically just melted.

[berndp]

I think that from a certain point on, temperature becomes a problem. And also the so-called lithoplastic deformation events set in. Further down you need temperatureproof drilling heads, eventually need of coolant. Water starts evaporating at 100°C, so thereafter something else would be required. But finally and even all this will reach a point from where everything won't remain solid, also the well diameter, equal what expensive superhard drillhead material you have in operation and undergoes permanent deformation, thermal thread, from where a "mechanical drilling" no longer can be done properly or even work because you are literally kneading your drillhead forward into lithoplastic mineralic masses, merely sooner or later transitioning into a consistence of lava.

When I was a kid we were digging a "foxhole" in my backyard playing Army and hit this weird black seam of what appeared to be coal in red clay. I dug up this weird bronze or brass colored bell with a nude lady on it wearing a weird cone shaped hat with flaps or horns hanging down on the sides and a cape or bat wings. It was half encrusted in the coal and I chipped it off. It had weird symbols on it that looked like what I now realize must have been futhark runes or some kind of pre-sanskrit. It was handmade and had no cast lines or maker's marks on it but you could faintly see where it had been hammered. It had no connection point inside for a tongue or anything. However, if struck with a stone it would put out this unusual tone that would last about 20 seconds that you could feel in the center of your brain like a tickle. I thought this odd because the tone seemed to last much longer than it should have but it was so satisfying and..enticing. Over the course of just a few minutes I sorta became addicted to that tone and wanted more. I kept dinging it and before I knew it the sky was getting dark and I looked over at the kids that were with me and they were frozen like in a trance. Time had gotten away from us. I wanted to take it to school for show and tell but my mom confiscated it due to the naked voluptuous woman and told me she would put it away for when I was an adult. A couple of nights after that I had a bizarre dream where a scantily clad and gorgeous woman with bat wings came to my window sort of humming or singing a sort of lullaby and I went to the window and let her in. She whispered something in my ear in a language I couldn't understand but somehow I knew she wanted me to lie back down in bed. I couldnt renember what happened after that. The next morning my Mom woke me up and asked me why there where flower petals on my pillow. I had no clue. There was dried blood on my lips but I had no wounds anywhere.
When I was 18 I asked for the bell back and she said she couldn't find it. Later my Grandmother told me that my Mom admitted to selling it at a garage sale along with a set of corelle dishes I won in a drawing when I was 9. I remember grammy saying it was for the best as the bell belonged to "the devil's bride".
Somewhere out there is an extremely important artifact found in Bossier City, LA in 1979 and some mook in the Shreveport Bossier area has it on their curio shelf. Way to go Mom. I could have rewritten history if you hadn't robbed your own son to get money to buy more giant spray cans of Aqua-Net hairspray, tupperware, and Benson&Hedges cigarettes.

Greetings from Sweden.

Thank you so much for this upload!
I love this topic!

[pieterprinsloo]

this is an amazing presentation. many thanks

At 17 seconds into the video, we are told (verbaly) that Earth's diameter at the equator is "twelve point seven five four" kilometers, not the true value of twelve thousand seven-hundred fifty-four kilometers. The problem, I think, is that the computer voice read the 'dot' as a decimal point (American usage) and not as a separator between the thousands and the hundreds place (European).
