Potentially Favourable Areas for Geological CO2 Storage in Portugal

Delimitation of areas and identification of geological formations with potential for CO2 storage in mainland Portugal and its respective Exclusive Economic Zone (EEZ). The areas were obtained from a combination of historical data (mechanical oil exploration surveys and their geophysical logs and geophysical prospecting using the seismic reflection method), lithostratigraphic interpretation, requirements for storage in saline aquifers, as well as an update of the results of the COMET, CO2STOP and HYSTORIES projects, carried out in the framework of the CSA-GSEU project (WP3 Geoenergy, thematic subgroup CO2 and Hydrogen Storage).

To update the areas with potential for large-scale geological CO2 storage, which were identified for mainland Portugal and its EEZ under the COMET project, with the following objectives:
i) to identify sites and geological formations eligible for further studies on the feasibility of storing CO2 captured from industrial sources;
ii) to contribute to the mitigation of global warming;
iii) to strengthen carbon market and management strategies.

Data Quality

Os polígonos e parâmetros da base de dados foram estabelecidos de acordo com a metodologia definida nos projetos COMET e HYSTORIES. José Sampaio e Susana Machado atualizaram a base de dados, nomeadamente as idades dos reservatórios (formações geológicas) e dos selantes (idem).
