The paper is dedicated to the balance selection in maximum production and minimum amount of injected steam based on the field data analysis. The preliminary technology analysis of efficient exploration of deposits with heavy and high-viscous oil applying thermic methods was carried out. The dynamics of steam injection and oil production was reviewed. The uncertainty of the processes taking place in formation system during steam treatment is marked. In addition, it is necessary to make decisions in the availability of a few criteria. The application of the methods known from the fuzzy-set theory and meant for decision-making in these conditions enables to achieve efficiency improve of steam treatment due to the oil production increase in minimum injected vapor.
