The operating conditions of oil and gas production and processing industry require improvement of information-analytical and statistical-methodological support of the project efficiency analysis. The paper gives theoretical and practical recommendations for setting the optimal price for economic weighted calculations. A set of criterion evaluations and the mechanism of multilateral evaluation of projects are defined. Methods for evaluating projects and optimizing their portfolios under conditions of scarcity and risk are proposed. The application of this methodology in oil producing domestic companies at all stages of exploration, production and processing of hydrocarbons will reduce the likelihood of economic losses, increase profitability of production, the material well-being of engineering and service personnel, which is especially relevant in conditions of falling oil prices.
