| 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. |

| Deformation processes during the development of hydrocarbon accumulations and their influence on the formation productivity | |
| The article presents the results of the analysis of time changes in the development parameters of a number of fields in the Apsheron oil and gas region (South Caspian basin). Taking into account world experience, it is substantiated that a significant drop (below hydrostatic) in reservoir pressures as a result of long-term development of fields is accompanied by a deterioration in reservoir properties of rocks. It is shown that technologically induced deformations of reservoir rocks affect their permeability to a greater extent, contributing to a decrease in well productivity. It is shown that the degree of depletion of various production facilities in the fields of the Apsheron oil and gas region is not the same, which is recommended to be taken into account when determining the strategy for their additional development. Keywords: oil and gas fields, long-term development, petroleum reservoir pressure, rock deformation, reservoir properties of rocks, well productivity, Apsheron oil and gas region, South Caspian basin. |

| Analysis influence of the reservoir lithofacial heterogeineity of the operating mode of the underground gas storage Galmas (Azerbaijan) | |
| In the paper analyzes of the monitoring results of the operational parameters of the Galmas underground gas storage, created in the same-named depleted gas-condensate field of Azerbaijan is given. The object of gas storage is the terrigenous rocks of the Lower Pliocene age - the Productive series. The generalization of the results of the executed studies allows to conclude that in the operation mode of the Galmas underground gas storage, along with technical and technological, there are certain geological problems associated with the spatial heterogeneity of the lithological composition of the rocks and its capacity-filtration features.
Keywords: underground gas storage, lithofacial heterogeneity, capacity-filtration feature, injection and extraction of gas, depleted gas condensate field Galmas, Azerbaijan. |
