Integrated modeling is a tool for managing hydrocarbon extraction process from a production facility which consisting of both subsurface and surface elements. The main purpose of the work is to optimize the operation of the infrastructure and plan procedures by using the integrated model of the Cenomanian reservoir. The present article is concerned with the stages of development an integrated model of a gas field of the Cenomanian reservoir of one of the fields in the Tyumen region, setting the elements, which include: 3D-hydrodynamic model, well models and a surface infrastructure model. The software package Petroleum Experts (Prosper, Gap, Resolve) is used. The hydrodynamic model and well models were adapted to the results of well test for correct integration. The stages of constructing the elements of the network, as well as specifying the compressor models by using gas-dynamic characteristics, are considered. The article analyzes the predicted technological parameters of the gas field operation according to the basic option, on the basis of which optimization approaches to the development of the Cenomanian gas field are formed – the use of reserve compression capacities, the construction of additional pipelines. The authors have proposed an additional algorithm to regulate the forecast calculation of gas production. The input data for the algorithm are the maximum gas production at the PK1 deposit and technological constraints for wells – the maximum and minimum gas production rate, the maximum drawdown. The program controls wells by selecting choke diameters to maximize gas production. In conclusion, a technical and economic estimation of the basic and alternative options was carried out, based on the results of which the most rational option for the development of the PK1 formation was determined.
