Abstract
Due to the high degree of production of oil reserves in Western Siberia, geological exploration has been carried out mainly on complex objects for the last 10 to 15 years. The complexity of the task increases because of the fact that the predictive properties of seismic data on such objects are not high. All this leads to low efficiency of geological exploration.
In order to increase the efficiency of geological exploration of complex objects, we have proposed a methodology, in which, based on the results of a comprehensive analysis of diverse geological and geophysical information, a model of the quality of hydrocarbon reserves has been built. The ranking of the zones of the quality map of reserves will justify the most effective strategy of geological exploration, that is, the strategy with the least risks. In proposed methodology, special attention is paid to assessing the economic impact of involving reserves in industrial development. Testing of the methodology on reservoir rocks of the J2/1 layer within the Surgut arch has showed its rather high forecast properties.
