Estudio sobre las posibilidades de almacenaje de CO2 en depósitos clásticos de la región noroeste de la cuenca Neuquina.

Abstract

Carbon capture and storage (CCS) is emerging as a key technology for mitigating climate change, providing a transitional solution between the use of fossil fuels and the adoption of renewable energy. This study aims to evaluate the clastic deposits of southern Mendoza and northern Neuquén as potential CO2 reservoirs and estimate their storage capacity. Through the analysis of well data, electric logs, 3D seismic data, and previous geological studies, the potential reservoirs and their capacity to store CO2 were assessed. The studies indicate that the petrophysical properties of the reservoirs in the study area are less favorable compared to other regions in northern Neuquén, limiting the viability of future CO2 storage projects. Furthermore, regional structures in the southern part of the area, which have the potential to act as CO2 traps, are affected by high-angle deep faults, compromising the integrity of regional seals and their ability to contain CO2. Regarding storage capacity, estimative calculations show a reduced potential, significantly lower than that of major global projects, indicating the need to evaluate alternative areas for CO2 storage.
