“…Effective use of resources in fractured-porous reservoirs requires an integrated approach, including geological modeling, hydrodynamic analysis, geophysical studies and technical expertise. Continuous research and development of new analysis, modeling and production methods are helping to improve the understanding and control of filtration flows in fractured porous reservoirs [9][10][11]. This includes the development of new geophysical methods, modeling of hydrocarbon migration processes and production technologies.…”

Currently, solving the problems of choosing a strategy for managing the process of oil deposits development with fractured-porous reservoirs is associated with a number of difficulties due to changes in the filtration and capacitance characteristics of the formations along the section and area, the presence of nonequilibrium effects, insufficient geological and field information, and the complexity of technological processes of offshore oil production etc. In this regard, increasing attention is being paid to the use of methods that make it possible to analyze the processes occurring in formation systems by processing indirect but accessible information, for example, flow rates of individual wells, production from areas and horizons, etc. The article discusses the problems of diagnosing the state of development of oil deposits with fractured-porous reservoirs and the principles of process regulation based on the cybernetic approach to the analysis of geological field information by an indirect method, such as analysis of the Gini coefficient. The Gini coefficient is used in economics to measure inequality in the distribution of a society's total income and the standard of living of different segments of the population. By analogy, it was used to determine the inequality in the distribution of oil and water withdrawals among the wells of the field under consideration during different periods of development. It has been established that the use of the Gini coefficient when interpreting geological and field information significantly increases the reliability of diagnosing the current state of the development process, which allows timely to make decisions on regulating the technological process. Based on a dynamic approach to the analysis of geological and field data, the article proposes principles for managing the development process of a fractured-porous reservoir of the oil field in question. The proposed analysis method for managing the process of developing oil deposits with fractured-porous reservoirs had good adaptation in the process of developing the field in question

“…2, b). In view of the fact that core studies revealed fracturing and the accepted average permeability for the reservoir identified by well logging is characterized by low values and amounts to 2 mD, and the WFT recorded an average value for the reservoir equal to 123 mD, it can be concluded that filtration mostly occurs via a well-developed system of fractures [19,20]. To approximate the HDM to the characteristics of a real reservoir, it is necessary to construct a dual-medium HDM, which considers filtration via the matrix and fractured components of reservoir [21].…”

Issues related to the influence of reservoir properties uncertainty on oil field development modelling are considered. To increase the reliability of geological-hydrodynamic mathematical model in the course of multivariate matching, the influence of reservoir properties uncertainty on the design technological parameters of development was estimated, and their mutual influence was determined. The optimal conditions for the development of the deposit were determined, and multivariate forecasts were made. The described approach of history matching and calculation of the forecast of technological development indicators allows to obtain a more reliable and a less subjective history match as well as to increase the reliability of long-term and short-term forecasts.
