The Kola Superdeep Borehole SG-3 (Russian: Кольская сверхглубокая скважина СГ-3, romanized: Kol'skaya sverkhglubokaya skvazhina SG-3) is the deepest human-made hole on Earth (since 1979), which attained maximum true vertical depth of 12,262 metres (40,230 ft; 7.619 mi) in 1989. [1]
The "Well to Hell", also known as the "Siberian hell sounds", is an urban legend regarding a putative borehole in the Siberian region of Russia, which was purportedly drilled so deep that it broke through into Hell. It was first attested in English as a 1989 broadcast by an American domestic TV broadcaster, the Trinity Broadcasting Network. [1]

This will be China’s second deep well after commencement of Asia’s deepest well in May
The Kola Superdeep Borehole was the longest and deepest borehole in the world for nearly 30 years. However, in May 2008, a new record for borehole length was established by the extended-reach drilling (ERD) well BD-04A, in the Al Shaheen oil field. It was drilled to 12,289 m (40,318 ft), with a record horizontal reach of 10,902 m (35,768 ft) in ...
