Taking a Look Inside the Earth

APEGGA, the Canadian Society of Petroleum Geologists, and the geology and geophysics departments at the University of Calgary invited two Russian researchers, Dr. Youri Kouznetsov (left) and Dr. Andrei Karakin, to present (on Nov. 23) their methods of investigation and the basic results from studying the Kola Superdeep Borehole in Russia.

Drilling of the borehole began in May 1970 in the northern part of the Baltic shield and was performed in three stages. The first stage, from 1970-1975, resulted in a drilled depth of 7,263 metres. The second stage, from 1976-1980, the depth moved to 10,636 metres deep and the final stage, from 1981-1995, the drilling reached a depth of 13,000 metres into the earth.
