The deepest well ever drilled by humans is the Kola Superdeep Borehole in Russia. It reached a depth of about 7.62 miles (12.262 kilometers). The borehole was started in 1970 and drilling continued until 1994, primarily for scientific research purposes to learn more about the Earth's crust. | Rodney Keith Copley
