The new approach to forecasting economic growth of the region, showing minimal requirements to a supply with information, is offered in clause. It is based on combinatory likelihood modelling of dependence of a parameter of economic growth from its reliability. The method we shall apply to regions with the expressed branch specialization for the period before realization of structural reorganization of economy. In the conclusion the forecast of growth of Republic Komi VRP up to 2020 is given − is shown, that it will make 4 − 6% a year at preservation of energy raw specializations.

In paper the investment’s forecast on the Timano-Pechora province hydrocarbon resources further exploration on purpose to transformation ones to stocks is given. Investment values are makes under forecasting resource low validity particularly their unexplored part. Various geological-mathematical methods and resource-capacity formula are used.

In this paper the existence of two equally main groups of the uncertainty of data (economical and geological) factors are fixed. The choice’s procedure of the mostly effective variants of the region’s hydrocarbon resources usage is offered. It based on the combinatorial-probabilistic technique of the economic evaluation and gas and oil usage movement choice, added by geologic-mathematical methods. The forecast of the gas and oil output in the Komi Republic after 2020 based on the unexplored resources are given.
