Resumo(s)
The continuous increase in anthropogenic CO2 emissions is acknowledged as a major driver of global climate change, making the development of effective mitigation strategies a scientific and political priority worldwide. In this context, geological CO2 storage stands out as one of the most promising solutions for carbon capture and storage technologies, due to its capacity to significantly reduce emissions from large-stationary sources such as industrial facilities and power plants. This approach consists of the controlled injection of CO2 into deep geological formations where it can be securely stores over long timescales, provided that the storage conditions are met. These conditions include the presence of reservoir rocks with favorable petrophysical properties, such as adequate porosity and permeability for storage combined with effective sealing rocks capable of preventing fluid migration towards the surface. In this context, this study aimed to evaluate the potential of geological formations for safe storage, through the identification and characterization of reservoir rocks and their associated seals, developed within the Master's program in Geophysical Sciences in collaboration with the NET4CO2 project. This study contributes to the advanced technical knowledge related to carbon storage along the coast of the Lusitanian Basin. The analysis was based on the integrated interpretation of geophysical data from 12 wells, with attention given to the characteristics, properties, limitations, and data quality associated with each dataset. Reservoir evaluation focused on key parameters derived from geophysical data, including porosity, permeability, and thickness, while seal assessment emphasized lithology, thickness, and low-permeability characteristics. The results improve the understanding of CO₂ geological storage potential in the studied sector of the Lusitanian Basin, supporting the development of future carbon capture and storage initiatives and reinforcing the role of this technology in mitigating carbon emissions and addressing climate change
