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.
Perhaps more importantly to the operator, Exxon Neftegas Ltd., the wells on this shelf are expected to produce a total of 2.3 billion barrels of oil.
That’s Some Serious Depth
Before the Z-44 Chayvo Well and other holes like it were drilled on the eastern side of Russia, the famous Kola Superdeep Borehole held the record for drill depth.
Located in western Russia, this time just 10 km from the border with Norway, the Kola Superdeep Borehole was rumored to have been discontinued in 1992 because it actually reached “hell” itself. At its most extreme depth, the drill had pierced a super-hot cavity, and scientists thought they heard the screams of “damned souls”.
All folklore aside, the Kola Superdeep Borehole is super interesting in its own right. It revealed many important things about our planet, and it still holds the record today for depth below the surface.
