Analiza zmienności polskich pokładów soli kamiennej w aspekcie magazynowania gazu
(2011) Ślizowski, Jarosław; Urbańczyk, Kazimierz; Lankof, Leszek; Serbin, Karolina
Until now, the only geological maps used in design of the location of underground gas storage facility in rock salt beds were contour maps showing thickness and depth of the deposit. On their basis, the possible locations of such storage facilities on the Foresudetic Monocline and the Leba elevation have been selected. Nevertheless, these types of maps are not sufficient enough to determine the optimal location, which in the case of gas storage caverns is a function of thickness and depth of the deposit. In the paper it is explained how maps of the attractiveness of the regions in terms of short-term and long-term storage capacity have been constructed. The presented results represent the first stage of the research and relate only to the analysis of geological and mining conditions.

Analytical prediction model of UGS performance
(2014) Blicharski, Jacek; Rybicki, Czesław; Stec, Grzegorz
The purpose of underground gas storage in porous media is to allow compensation for peak shaving in gas consumption. Especially during the winter months, the stored gas must then be supplied at fuli capacity for short periods. Currently storage capacities of existing UGS facilities in Poland are not fully sufficient for proper regulation of gas demand. The more they do not overcome long term limitation in gas supply from import. There is therefore a need for increasing capacity of existing UGS or development of new ones. This paper presents an analytical model based on equations of material balance combined with well inflow and tubing performance equations for modeling gas storage operations. Presented model was used to maximize the capacity and efficiency of natural gas storage developed in partially depleted gas fields located in the region of south-eastern Poland for a given reservoir/well configuration. On the basis of this model variant scenario of gas storage operation with the use of vertical and horizontal wells were demonstrated.

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.

Podziemne magazyny gazu ziemnego w wyeksploatowanych kopalniach węgla
(2007) Siemek, Jakub; Nagy, Stanisław
Restructuring of coal mining industry in Poland after 1989, and so the closing of about 40 deep mines, prompted analyses of the potential applicability of abandoned workings as gas or liquid fuels storages. Foreign solutions making use of abandoned excavation and natural pore space for storing hydrocarbons. The UGS should be construed when the dewatering system is operational. Issues related to the environmental hazard during construction and exploitation of UGS in abandoned mines as are described. The economic analysis of the cost of two separate UGS in selected mines has been done. The two selected mines have the largest methane capacity, accounting for total capacity of workings and old workings, as well as sorption capacity of the left out coal. The analyses prove that the conversion of mines from Upper Silesian into underground gas storages is possible.

Prognoza ekonomiki podziemnego magazynowania gazu w Polsce
(2007) Stopa, Jerzy; Rychlicki, Stanisław; Kosowski, Piotr
Issues related with economics of underground gas storages in Poland are presented in view of the situation in Europe. The basic analyzed topic is prices of commercial gas storing. This type of activity is not presently carried out in Poland, though it might be if the available storing space was increased, and competition of Polish Oil and Gas Company came on market. Selected prices in some Europe's countries are presented, whereas the variants of forecast commercial prices are given in view of the economic and technical assumptions. The results of calculations reveal that the prices of UGS in Poland could be competitive in relation to the West European prices.

Role of underground gas storage in the EU natural gas market
(2014) Janusz, Piotr; Kaliski, Maciej; Szurlej, Adam
One of the main intentions of the European Union is to create common and liberalizated market of natural gas in Europe. Actions has been taken in this area for a few years, however achived effects do not reach the aims that were assumed at the beginning. The quantity of natural gas consumption in the European Union during last years is characterized by a declining tendency (decreasing usage of natural gas in power sector, higher temperature during autumn and winter season also infulences on limiting of natural gas demand), in 2012 the consumption was forming on the level of 444 billion m$^{3}$, and for example in 2008 it amounted to 497 billion m$^{3}$. The regulations concerning the natural gas market embrace all of the elements which have an impact on building consolidated and liberalizated market, it means: transfer, distribution and LNG, storage. The authors of this article wants to draw one's attention to the particular role of underground gas storages and depict change of the tasks, which they have to fulfill on the liberalizating market of natural gas in Europe (ie. Price arbitration). The purpose of this article is to present the current situation on the market of storage services, which means available storage capacities, the level of their usage and plans regarding extension and constructing of new capacities.

Ruch wody w złożach węglowodorów i podziemnych magazynach gazu
(2007) Rybicki, Czesław; Blicharski, Jacek
When a well starts its operation on a deposit or underground gas storage, a zone of lowered pressure is formed around it, enabling reservoir fluid inflow. Later in time the pressure is disturbed, also affecting the hydrated zone, and causing water flux to the well. Irregular forms, e.g. „tongues” or „water cones” are formed at that time. In reservoir engineering there are various methods of determining the admissible yield in view of the water cone formation. Irregular forms of water migration have a great influence on the process of gas exploitation from a deposit, especially from an underground gas storage. They are frequently the main reason of pressure drop in the well, needed for carrying up the gas-water mixture. In the extreme case, water flowing to the well may be not exploited with gas. Then it is accumulated on the wellbore bottom, stopping the gas inflow, and so leading to the gradual stopping of production. Thus the movement of reservoir water and its tracing is especially important during underground storing of gas, when the water cyclically moves within the reservoir. The main methods of calculating the water flux to a well was analyzed and the movement of reservoir water was investigated in the case of a sharp gas-water interface. This signifies that capillary forces were neglected and gas is expelled by water as a result of 'piston' effect. Piston expulsion of gas by water is a reasonable assumption owing to a much bigger density and viscosity of water as compared with gas.

(2008) Kosowski, Piotr; Rychlicki, Stanisław; Stopa, Jerzy
Issues related with economics of underground gas storing are presented in the paper. Changes in the gas market caused by liberalization policy promoted by the European Union require taking a new look on underground gas storing issues, especially economic efficiency. Inevitable formation of free and competitive market of storing services makes the operators learn the key elements of the storing installations influencing the achieved economic results. The influence of the degree of gas storage utilization on its economic efficiency and minimum price for natural gas storing services (providing the assumed return rate) is analyzed in the paper. The calculations were made for an exemplary gas storage, with the use of financial models worked out by the authors.
