Abstract: The article presents the results of an analysis of geological, geophysical, and hydrogeological data accumulated to date for the Ili sedimentary basin to identify potential geological structures capable of trapping and storing carbon dioxide (СО2 ) emitted by industrial facilities in Almaty and the Almaty Region under geographically favorable and economically viable conditions. Data from seismic exploration, drilling, and well studies were used to study the features of the geological structure of deep stratigraphic horizons and the structural-tectonic conditions of their occurrence. Based on the results of geological modeling in the Petrel software, structural, lithological, and petrophysical models were constructed, which made it possible to determine the effective reservoir thicknesses of the Jurassic storage formation capable of trapping СО2 . Based on well data, a quantitative assessment of the distribution of reservoir properties (porosity and permeability) for the Jurassic deposits was performed. Their effective pore volume was calculated, reaching 2,918.6 thousand m3. The hydrodynamic conditions at the depth intervals of the Miocene-Paleogene and Jurassic sandstones exceed the critical parameters for carbon dioxide, at which СО2 transitions into a supercritical fluid state. This allows these horizons to be considered as reservoirs capable of absorbing and ensuring the long-term, safe storage of СО2.
