The Kola Superdeep Borehole (Russian) is the result of a scientific drilling project of the Soviet Union in the Pechengsky District, on the Kola Peninsula. The project attempted to drill as deep as possible into the Earth's crust. Drilling began on 24 May 1970 using the Uralmash-4E, and later the Uralmash-15000 series drilling rig. Boreholes were drilled by branching from a central hole. The deepest, SG-3, reached 12,262 metres (40,230 ft; 7.619 mi) (Needs verification. According to written markings on the borehole, the depth is 12,226 m, 1989 in depth) and is the deepest point on Earth, as of May 2019. The borehole is 23 metres (9 ft) in diameter.In terms of Earth's crust. Drilling began on 24 May 1970 using the Uralmash-4E, and later the Uralmash-15000 series drilling rig.
