Development of software for creating and visualising technological schemes of gas flow in underground gas storage facilities for forecasting their operation modes

<ns3:p>The objective of the study is to develop software for analysing the performance characteristics of individual technological facilities of underground gas storage (UGS) facilities. The software will determine the forecasted performance indicators and operating modes of gas storage facilities.The paper provides an in-depth analysis of the technological processes involved in withdrawing and injecting gas from/into underground gas storage facilities. Following an analysis of the initial data from the technological equipment, a database structure was developed and created. The software provides an object-by-object analysis of performance characteristics for individual technological units of gas storage facilities, enabling users to determine their predicted performance indicators, technological limitations, and optimal operating modes. Modules were developed to collect, process, and view data, as well as perform the necessary calculations.Based on the results of the work carried out, specialists will be able quickly to solve problems related to determining the forecast indicators of operation of UGS facilities and conduct an object-by-object analysis of their operation mode to identify the least efficient sections of the technological scheme in terms of hydraulic efficiency and productivity in different operating modes.To enhance the efficiency of UGS operations, it is recommended that the necessary software be implemented to calculate the predictive modes of operation of UGS technological units and to create a catalogue of their performance characteristics.The results of the work carried out allow specialists to create design schemes for UGS facilities that provide the ability to conduct a detailed, facility-by-facility analysis of the performance characteristics of individual process units. The analysis allows users to determine the forecast performance of both individual process facilities and UGS facilities as a whole.It is proposed that software be developed to determine UGS modes, considering the performance of the relevant technological equipment. Applying the approach ensures the efficiency of analysing UGS modes and selecting the optimal one.</ns3:p>
