    Assessment of expected tightness of Uhřice-jih underground gas storage
    (Wydawnictwa AGH, 2023) Horáková, Markéta; Rado, Robert; Bujok, Petr; Klempa, Martin; Kunz, Antonín; Křístek, Matěj
    Underground gas storages (UGS) are an essential part of gas transmission systems in almost all countries that consume significant amounts of gas. This is because maximum capacity of transportation system cannot cover increased seasonal or any peak demand. The UGS’s systems are used as buffers to guarantee security and reliability of gas supply. The safety of UGS operation is ensured by the tightness of the storage geological structures, technical and technological equipment, which are known as primary and secondary tightness. This article evaluates the primary tightness conditions of selected Uhřice-jih UGS in the Czech Republic owned by MND Gas Storage a.s. Monitoring and control of the gas quantity balance in the reservoir was carried out using p/z curves method and based on mathematical modelling. In the article some of the aspects of secondary tightness UGS monitoring are also illustrated.
