Why did Russia stop digging the Kola Superdeep Borehole?
Drilling was stopped in August 1994 at 8,578 metres (28,143 ft) of depth due to lack of funds and the well itself was mothballed.
The Kola hole was abandoned in 1992 when drillers encountered higher-than-expected temperatures—356 degrees Fahrenheit, not the 212 degrees that had been mapped. The heat wreaks havoc on equipment. And, the higher the heat, the more liquid the environment, and the harder to maintain the bore, said Andrews.
The temperature of the rock at 12 kilometres deep was much higher than scientists thought it would be. They had prepared for temperatures close to 100 degrees Cecius. But the rocks were much closer to 180 degrees Celsius! They weren't prepared for this extreme heat, so they had to stop digging.
Upon falling to about 200 kilometers deep (3% of the way to earth's center), your dried up bones and remnants of flesh encounter a temperature of about 1200 Kelvin and are completely incinerated into dust. Your dust remains then fall the rest of the 6200 kilometers (97% of the way) to the earth's center.
In a word, no. The center of the Earth is roughly 3,959 miles (6,371 km) down. The deepest hole that was ever drilled was the Kola Superdeep Borehole, at 7.6 miles (12.26 km) deep. That's 0.19% of the way to the center of the Earth.
Deeper than the deepest point of the ocean - the Mariana Trench. In fact, this is the deepest hole we've ever dug into our planet. It's called the Kola Superdeep Borehole, and for once, it has nothing to do with extracting fossil fuels. The borehole exists purely for the wonderful science of it all.
The world's deepest oil well, known as Z-44 Chayvo, goes over 40,000 ft (12 km) into the ground – equal to 15 Burj Khalifas (the tallest skyscraper) stacked on top of each other. That's also equal to 2x the record height for air balloon flight.
The deepest hole by far is one on the Kola Peninsula in Russia near Murmansk, referred to as the "Kola well." It was drilled for research purposes beginning in 1970. After five years, the Kola well had reached 7km (about 23,000ft).
So scientists rely on seismic waves—shock waves generated by earthquakes and explosions that travel through Earth and across its surface—to reveal the structure of the interior of the planet. Thousands of earthquakes occur every year, and each one provides a fleeting glimpse of the Earth's interior.
The reason that U.S. oil companies haven't increased production is simple: They decided to use their billions in profits to pay dividends to their CEOs and wealthy shareholders and simply haven't chosen to invest in new oil production.
Why won't the US drill more oil?
The biggest reason oil production isn't increasing is that American energy companies and Wall Street investors are not sure that prices will stay high long enough for them to make a profit from drilling lots of new wells.
That would cause you to fall at terminal velocity, and you'd end up stuck at the center of the Earth, completely weightless and helpless. I'm sure the engineer in you is screaming obscenities at the screen right now. We can barely dig a tunnel just a few kilometers into the reasonable outer crust of the Earth.

Well, it depends what you mean by “bottom.” Earth is a ball, so if you want to dig to the center of it, it's 3,958 miles. But if you want to dig all the way through and pop out the other side, it's twice as far, or 7,916 miles.
A scenario often presented to introductory physics classes is that of a "gravity tunnel" — a tube drilled from one side of the Earth to the other through the planet's center. The answer taught for nearly a half-century for how long a fall through such a hole would take was about 42 minutes and 12 seconds.
Solving the problem numerically, Klotz found that an object should fall through Earth in 38 minutes and 11 seconds, instead of the 42 minutes and 12 seconds predicted assuming a uniform planet.
Deep in the centre of the planet is the 'inner core', which we think is made of solid iron and nickel. This is surrounded by the 'outer core', which is also made of iron and nickel, but is molten. Convection currents in the outer core create Earth's magnetic field.
"Our new findings indicate that the core may contain as much as 1,200 parts per million potassium -just over one tenth of one percent," Lee said. "This amount may seem small, and is comparable to the concentration of radioactive potassium naturally present in bananas.
No. The Earth has a lot of mass and moves extremely quickly in its orbit around the Sun; in science speak, we say its 'momentum' is large. To significantly change the Earth's orbit, you would have to impart a very great change to the Earth's momentum.
These maps clearly indicate the Mariana Trench as the deepest of its kind, and so far the Challenger Deep is its lowest measured point. Chances are, if the depth or the location of the world's deepest point ever does change, it won't be by much.
Challenger Deep is the deepest point in the world ocean. Located within the already-deep Mariana Trench in the western Pacific Ocean, the actual deepness of Challenger Deep strains the imagination.
Has anyone been to the bottom of the Mariana Trench?
While thousands of climbers have successfully scaled Mount Everest, the highest point on Earth, only two people have descended to the planet's deepest point, the Challenger Deep in the Pacific Ocean's Mariana Trench.
Oil Reserves in the United States
The United States has proven reserves equivalent to 4.9 times its annual consumption. This means that, without imports, there would be about 5 years of oil left (at current consumption levels and excluding unproven reserves).
The deepest well drilled in the U.S., the Lone Star Bertha Rogers No. 1, was completed in 1974 as a dry hole in the Anadarko basin in Washita County, Oklahoma. The well was drilled as a wildcat to a depth of 31,441 ft.
Petroleum refineries in the United States produce about 19 to 20 gallons of motor gasoline and 11 to 12 gallons of ultra-low sulfur distillate fuel oil (most of which is sold as diesel fuel and in several states as heating oil) from one 42-gallon barrel of crude oil.
'Kola Superdeep') is a 2020 Russian horror film directed by Arseny Syuhin, based on the real-life Kola Superdeep Borehole. The film focuses on a group of researchers and soldiers who investigate the mystery surrounding reports of a disease outbreak at a secret underground research facility in 1984 Russia.
