Deep drilling poses major problems when high temperatures, high pressures, and acid gases are encountered. A combination of these items usually requires extensive planning, exotic materials, long drilling times, and heavy expenditures. Only 2 wells have been drilled below 30,000 ft in the US, the deeper a 31,441-ft hole in 1974. The deepest well in the world is reported to be in the Soviet Union, recently drilled below 34,895 ft, with a target depth of 15,000 m (49,212 ft). A review of current deep drilling technology and its capabilities is given.
