The Project of the Deep Well Drilling in the Pauzhetsky Geothermal Area


[Institute of Volcanology and Seismology FEB RAS, Russia]

The well of the Icelandic project RN-15 / IDDP-2 in Reykjavik has reached supercritical geothermal conditions. The research and practical results of this project are of exceptional interest for similar projects in other volcanic regions. Kamchatka is one of the promising regions. Eichelberger J. and Kiryukhin A. proposed a scientific drilling project at the Mutnovsky volcano (Eos, Vol. 87, No. 50, 12 2006, p 569). The implementation of this project is very difficult, since the well site is at a large absolute elevation. Often there is stormy weather and most of the year there is a thick cover of snow. Pauzhetsky hydrothermal-magmatic system in the Southern Kamchatka is the best variant for this project. This area is located in the transition zone from the Kuril island arc to the continent. Geology and hydrological-geothermal conditions are studied here in detail, using several dozens of geothermal wells. The maximum depth of one of them is ~1200 m. The maximum temperature of formation of hydrothermal minerals is ~330°C. The Ministry of Education and Science of the Russian Federation supported the project No. 14.W03.31.0033 “GEOPHYSICAL RESEARCH, MONITORING AND FORECAST OF THE DEVELOPMENT OF CATASTROPHIC GEODYNAMIC PROCESSES IN THE FAR EAST OF THE RUSSIAN FEDERATION” supported the grant and allocated funds for the installation of 75 seismic stations which will record information about deep activity under the Far Eastern volcanoes, including the volcanoes of the Pauzhetsky geothermal area. Its structure contains volcanoes with magmatic chambers in the Earth's crust. A pilot industrial well is planned to be drilled close to the extrusion into the zone of influence of a magma chamber in the upper crust. The supercritical heat transfer agent can be used to increase the capacity of the Pauzhetsky geothermal power station and for the transmission of electricity to Petropavlovsk-Kamchatsky.
