Optimization of gas injection and withdrawal in underground facilities

At present, reliable supply of natural gas is considered one of the main geopolitical priorities in many regions of the world, including Europe. Storage of gas in underground storage facilities and increase the efficiency of the system, lowering costs and losses, is very important in terms of process automation and management of modern methods. During the year, the month or the use of gas as a result of uneven gas consumption (dozens million cubic m). It is difficult to create large surface gas storage facilities to store this gas. Therefore, it is more efficient to create underground gas storage facilities to regulate unequal gas consumption. According to the general gas supply scheme of any industrial and residential center, the main gas pipeline system operates with a stable capacity throughout the year. In the autumn and summer months, the excess gas is pumped into the underground gas storage, and in the winter months of the year, the excess gas is supplied to the gas operators. The required volume of gas in underground gas storage facilities in order to determine the schedule is laid out in annual spending.The gas supply system of underground gas storage facilities in places far away from the main gas pipelines When you use 30% of capital expenditure, 15-20% decreases in the cost of gas transportation. In this case, the creation of underground gas storage costs will be reduced by 2.5-3 years.
