Nine oil and gas fields have been discovered in the Severny district of the Novosibirsk region. The Verkh-Tarskoye field is the largest one. The most active mining operations were carried out from 2004 to 2011. As a result of super-intensive recovery techniques the “health” of the Verkh-Tarskoye field was undermined, and the production began to plummet. At that, the district is characterized by unique variety of geological conditions. There is oil in Jurassic sandstones (Verkh-Tarskoye field), in the carbonate Paleozoic (Maloichskoye field) and even in Mezhovskie granites. The author assumes that this is the most promising target for geological and geophysical observations and field studies, testing and duplication of innovative technologies across the entire spectrum of oil and gas production. For reliable field simulation it is extremely important to conduct research based on continuous monitoring of all main parameters of living fluid-rock system; birds are preferably to lower directly into the payout bed. The study of high-temperature deep-seated focuses is of particular interest. The Maloichskaya 4 well (near the Verkh-Tarskoye field) has the temperature of 160°C at the depth of 4500 m. A lot of wells in West Siberia have the temperature of more than 100°C in oil reservoirs. The use of deep heat means getting a new large-scale source of energy. With assistance of state authorities and oil companies, the mentioned district can become an international providing ground for solving a number of scientific and technological problems with obligatory participation of SB RAS institutes.
