To carry out reliable calculations to determine the quantity of commercial products and the parameters of the collection system in the area from the bottom of the well to the point of delivery to the consumer, there is a need to use both training models and collection system models, each of which describes its part of the process. An integrated approach to modeling allows us to describe the production process in more detail and to get away from the assumptions that are characteristic of generally accepted approaches to modeling. As a result, iterations aimed at coordinating the decisions on the development of the reservoir with the decisions adopted on the surface infrastructure are minimized. Using an integrated modeling approach allows you to quickly perform calculations of the forecast profile of hydrocarbon production, taking into account all the elements of the reservoir - well - collection system - gas processing facility system, find bottlenecks in the collection and preparation system, and optimize the system according to various criteria.

To date, Rosneft Oil Company has created an integrated model that includes a hydrodynamic simulator of the license area in the format of the Eclipse E100 simulator, a gas collection network model in the IPM GAP software, and a gas treatment model in the HYSYS software package. The article describes the integrated model used and provides examples of solving practical problems that arise during the development of a gas condensate field: forecasting and optimization of technological modes of well operation, optimization of field operation in accordance with given restrictions, calculation of gas-gathering system reconstruction options, conceptual design of compressor equipment, calculation of the optimal mode work apparatus training installation. The article also presents the advantages of an integrated modeling approach in comparison with traditional industry approaches.
