Maquinaria Lorenzana S.A.

Proposed as scientific project in 1962 the hole was a scientific excavation whose objective was to achieve a very deep layer of Earth about 15 kilometers deep. Started the excavations in the year 1970 with the use of two units of huge machinery, of around 64 meters, the "Uralmash-4E" and later the improved "Uralmash-15000″, the project resulted in several branches of a central branch, of which the SG-3 proved to be the most deep reaching 12,262 kilometers of depth." Although the initial intention was to reach the 15 KM, factors, unexpected, as the reconfiguration of the rock layers incredibly faster than those of the surface, made it impossible to move forward. Among the significant discoveries that left stunned geologists, include "youth water", i.e. deep water, in a liquid state when it was theoretically impossible for water to exist in liquid to these depths; it was also discovered that temperature increases in depth at a much higher ratio than it was believed. However one of the biggest discoveries was finding fossils of plankton whose molecular composition varied greatly compared with the fossils of the surface.
