Viktor Ryabchenko, Director General of OAO Slavneft-Krasnoyarskneftegaz, and Sergey Shlenkin, PhD in Technical Sciences, Chief Executive of OOO Slavneft-Nauchno-Proizvodstvenny Tsentr (OOO Slavneft-NPTs), became the 2008 winners of the Russian Federation Government Prize for Science and Technology.
V. Ryabchenko and S. Shlenkin were awarded with the Prize for their participation in creation and implementation of the innovative seismic and acoustic technologies for oil and gas fields’ exploration and development.
The above-mentioned technologies were created on the basis of the results of theoretical and experimental research carried out since mid 1980-ies by the group of scientists and specialists under the guidance of Oleg Kuznetsov, Professor, and Doctor of Engineering Science. For the years of the teamwork, the corporate authors, including Sergey Arutyunov, Candidate of Geological and Mineralogical Sciences, Boris Melchuk, PhD in Technical Sciences, Igor Chirkin, Candidate of Geological and Mineralogical Sciences, Valery Dyblenko, PhD in Technical Sciences, Sergey Karnaukhov, Candidate of Geological and Mineralogical Sciences, Yury Kuryanov, Doctor of Engineering Science and Yriy Lukyanov, PhD in Technical Sciences, along with O. Kuznetsov and Slavneft representatives, enabled to create the following fundamentally new seismic methods for exploration of oil-and-gas bearing zones:
 
- Seismic Locator for Lateral Survey Technology (SLBO-technology) was created for exploration of open fracturing zones and geological environment of oil fields;
 
- ANCHAR Low-Frequency (Infrasonic) Seismic Survey Technology is based on the effect of elastic energy absorption by oil and gas deposits and on further activation of natural oscillations within the sub-audio range. It enables to discover directly the hydrocarbon accumulation at the surveyed area;
 
- Technology for Seismic Location of Emissions Chambers (SLOE-technology) was created for diagnostics of the geological environment state and characteristics. This technology is based on the use of seismic emission waves induced by natural or industrial processes in the sedimentary section what enables to evaluate the heterogeneity of oil content in hydrocarbons traps, the efficiency of formation stimulation and to control the flood front advance;
 
- The complex of technologies for Seismic and Acoustic Effect on the Productive Area was created to increase the oil recovery efficiency. The harmonic and impulse effect on the productive area through elastic vibrations within the seismic and acoustic range together with hydrodynamic and thermodynamic impact is used to enhance the wells productivity and the recovery of reservoirs with difficult oil.
 
For several years OAO NGK Slavneft has successfully applied the SLBO-technology to the license areas in Krasnoyarsk region. In cooperation with Innovation and Research Company Geoacoustic (Moscow), the Company’s Subsidiaries, OOO Slavneft-NPTs and OOO Slavneft-Krasnoyarskneftegaz, developed the effective technique for geological survey of subsurface resources within the Kuyumbinsky and Tersko-Kamovsky Blocks. The combination of the two-dimensional seismic profiling (2D seismic survey) and the specific SLBO- technology (3D seismic survey) enabled to detect the main geological aspects of the territory and to forecast the most fractured and, as a consequence, the most productive zones of the Riphean deposits.
The integrated use of the received data enhanced the efficiency of exploration activities at these fields. Drilling efficiency significantly increased production and amounted to 90%. The results of the seismic surveys also allowed proving the new model of the Riphean productive complex structure and defending the data related to C1 and C2 oil reserves in the State Reserves Commission.
At present, OOO Slavneft-Krasnoyarskneftegaz is an oil industry leader by the rates of oil recoverable reserves increment in the region. Starting from 1998, the Subsidiary enabled to increment over 115 mln tons of C1 category oil reserves and 147 mln tons of C2 category oil reserves.
