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

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

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

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.

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

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

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

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.

Thank you for this. Very interesting!

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.

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.

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.

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.

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

I was lucky to meet the lead mechanical engineer of the design of the drilling equipment for the Kola peninsula site. We had a business meeting where we needed to establish the requirements for the electric motor we wanted to sell them for the new oil drilling equipment. The drilling equipment for the Kola peninsula had it´s type designation, but I forgot the full name. I only remember that there was number 15000 in the type designation, depicting the maximum depth of 15km, while we worked for 7500 type (7,5km). So, once we finished the main topic of the meeting, they asked us to try to consider development of electric motors for their new version of 15000 equipment. It was literally double the power of the one we just finished the discussion about. So, we initiated this interesting topic. They told us that they tried their equipment only once (in this particular experiment) and lost around 12 drilling heads with kilometers of drilling pipes left in the soil. One very interesting point they shared with us: the drilling pipe column made 30-40 turns in reverse after they switched off the motors and prepared themselves for pulling the coulmn out. So, the main purpose for the equipment was - drilling the earth for those very deep oil sources (10km+), and the secondary to investigate the Earth´s mineral content at that depth. The manufacturer company of the equipment is URALMASH, located in Ekaterinburg, Russia. I was more than happy to see some of those people, and last but not least: we finished the discussion about the topic by debunking the myth - there was no microphone going down the hole and there were no screaming voices coming from down deep. You need to search for the hell in a different place.

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.

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

this is an amazing presentation. many thanks
