Exploring the Viability of Underground Gas Storage Facilities in Southeastern Kazakhstan: Ensuring a Stable Gas Supply for Almaty, the Nation's Largest Metropolis

Abstract

The growing energy demand in Almaty, Kazakhstan’s largest metropolis, necessitates a reliable gas supply, making underground gas storage (UGS) a strategic solution. This study evaluates the feasibility of developing UGS facilities in southeastern Kazakhstan, specifically within the Pidzhim structure of the Zharkent trough. The geological and geophysical analysis identifies favorable conditions for gas storage, including the presence of anticline structures that meet UGS reservoir requirements. In addition to assessing the region’s hydrocarbon potential, the study examines key geotechnical characteristics, caprock integrity, and hydrodynamic properties that support the suitability of the structure for long-term gas storage. The findings highlight the Pidzhim structure’s potential as a prime candidate for UGS development, which could significantly enhance Almaty's energy security and regional stability. Future research should focus on reservoir performance modeling and a comprehensive assessment of the environmental and economic aspects of UGS implementation.
