A number of deep and superdeep wells have been drilled in Russia. The wells where all drilling activities have been finished, but the research activities still continue, are of a great scientific and practical interest for studying the present-day geological processes taking place in the Earth's interior. Vorotilovo deep well (VDW), drilled in a central part of Russian platform, is one of those wells-geolaboratories. The depth of the well is 5374 m, the temperature at the bottom is 95°C, open borehole in the range 689–5374 m. |
