The project attempted to drill as deep as possible into the Earth's crust . Drilling began on May 24 , 1970 on the Kola Peninsula , using an "Uralmash-4E" and later an "Uralmash-15000" drilling rig. A number of boreholes were drilled by branching from a central hole. The deepest, SG-3, was completed in 1989, creating a hole 12,261 m (about 40,226 ft or 7.62 mi) deep, [1] which is still the deepest hole ever drilled. The longest hole ever drilled is the 12,290 m (about 40,320 ft or 7.64 mi) long Maersk Oil BD-04A well at Al-Shaheen field in Qatar. [2]
