Abstract: Purpose: The work is devoted to the numerical implementation of the filtration model of reservoirs and the algorithmic model of compressor stations operated at underground gas storage facilities. Design/Methodology/Approach: For this, fast-converging methods and algorithms of minimum complexity are proposed for calculating the hydraulic parameters of the gas filtration process in heterogeneous reservoirs with concentrated sources and modes of operation of multi-shop compressor stations with various types of gas pumping units. The proposed methods and algorithms became the basis for the development of mathematical methods and software, which is operated by the dispatching service of underground gas storages. The time parameters of the proposed methods and algorithms made it possible to formulate the optimization problems of dispatch control of processes at underground gas storage facilities and to solve them effectively. The developed software are separate modules of the integrated complex that ensured: optimal planning, analysis of UGS operating modes and calculation of technical productivity; use it for optimal daily balancing of gas in the GTS. Findings: Among the advantages of this research (compared to similar ones known at this time), two should be highlighted, representation of the filtering area by different models and a combinatorial optimization method with adjustable complexity was developed. Practical Implications: Special attention is paid to the problems of model adaptation based on the results of numerical experiments. The main difficulty in carrying out adaptation lies in the significant uncertainty of the parameters of the studied facilities and, accordingly, their models, as well as input data and parameters of empirical expressions. The performance of the developed mathematical methods and software was confirmed by the results of numerical experiments and work in the mode of industrial operation for six years. Originality/Value: The article presents methods and tools for the effective dispatch contro of underground gas storage facilities.
