The purpose of scientific work is the development of range of tools and methods for the formation of opportunities rating of the Gazprom Neft, and for preparation of optimal business cases of basic production at operating fields of the Company. Due to a new approach of the assessment of oil production potential, there is an opportunity to promote an aggregate value of portfolio of Company’s Exploration and Production Unit through the development of the best complex decisions and research ways for increased efficiency of the basic production.

In this paper, the way of top-level assessment of the current state of reserves recovery considering geological and infrastructural complications, as well as technical features of well fund operating, was considered. This assessment allows to receive two rates: the rate of complexity and the rate of development, which provide an opportunity to assess not only the current state of object in general, but to use it as a factor when forecasting oil production in short and long terms. The modification of these rates allows to raise or to low the production of residual oil both on integral and experimental-industrial works levels. Automation of this module involves constant monitoring of all fields of the Company, which, in turn, allows to make a decision for the development of an additional program of well interventions techniques in time, in case of changing of actual oil production profile from the planned one. This module suggests reducing the load on product engineers and allows to present all aspects of the field (considered object) in a single format for monitoring.
