pdf Underground natural gas storage in Azerbaijan: current status and prospects
In recent years, a number of large gas condensate fields (Shah Deniz, Absheron, and Umid-Babak) have been discovered in the deepwater South Caspian Basin. Gas condensate accumulations are also expected to be discovered in other promising structures. Therefore, the main objective of this article is to analyze the prospects for increasing underground gas storage capacity in Azerbaijan, both by expanding the capacity of existing underground gas storage facilities (Garadagh and Galmas) and by creating new storage facilities at new geological sites. This study utilizes geological and geophysical data (seismic exploration and well logging results) and field data (total well productivity and well dynamics), processed and graphically plotted using standard computer programs. As a result of these tasks, the following potential sites are proposed for underground gas storage: productive unit VI (Lower Pliocene) of the Galmas structure, which is in the depletion stage; productive unit VIII of the southern flank of the Garadagh structure; and the Nehram and Tumbul areas in the Nakhchivan Autonomous Republic, where additional studies using modern technologies are recommended to assess the feasibility of creating underground gas storage facilities in salt and presalt strata.

Keywords: underground gas storage, gas condensate field, productive unit in the depletion stage, salt and presalt strata, South Caspian Basin, Azerbaijan.
