Key words: geological model, facies, integrated approach, risks evaluation, decision trees, oil fields development.

The article considers the experience of application conceptual geological models in Gazprom Neft JSC. Gazprom Neft pays great attention to developing integrated fields development plans, including the study of the geological basis. Under low quantity of data seismogeological and facies models has a big importance. An integrated approach to the understanding of modern geological deposits on the basis of the history of its formation, ways of hydrocarbons migrations is an important phase in the life of the oil and gas project.

Key words: seismic inversion, forward modeling, petrophysical study.

Recently, a tendency of state-of-the-art technologies designed for prediction of HC reservoir properties basing on seismic and well log data to fail producing the expected results has been observed. This may be due to a number of objectively reasonable causes, namely, complexity of seismic and geological characteristics, reservoir is not enough contrast in terms of elastic properties, and insufficiency of input geological and geophysical information. This paper discusses the questions of seismic inversion feasibility assessment in the stage of planning a work and setting a problem. Before carrying out inversion transformations, the integrated performance of such procedures as seismic data quality assessment, petrophysical substantiation of seismic inversion, and forward modeling is recommended. All this will allow to eliminate unreasonable time and financial costs.

The maps have been built using recent facial classifications and method of lithological number. North-eastern and eastern areas of investigated territory have been revealed as most perspective for further oil prospecting.

Integration of service market in Russian petroleum industry develops mainly due to penetration of foreign companies with new equipment and technologies. There are only few examples of Russian service companies that propose and perform research and design products on foreign markets. Today Russian research and design institutions use the same software, methodic of data processing and analysis of field information but nevertheless procedure of work management, consideration differs from foreign approach. An experience of design work on oil field development for foreign operators is presented. The main issues and differences of foreign approaches to research and design of oil field development (Field Development Projects, Full Field Review) are considered in the paper.
