Resumo:

The Paraná Basin represents an enormous potential for Brazil concerning implementing carbon dioxide capture, utilization and storage (CCUS), a critical technology to ensure a global clean transition. The relevance of the Paraná Basin relies not only on its stratigraphic sequence with a thickness of over 7 km but also because this basin happens to hold most of the CO2 stationary sources of the entire country. Thus, CCUS can offer a feasible CO2 mitigation solution for the south-eastern region of Brazil. Furthermore, the Irati Formation is one of the lithologic units within the Paraná Basin that exhibit a high prospect for CO2 geological storage. The purpose of this chapter is to conduct a prospectivity mapping looking to identify the most favourable areas. The methodology consists of a geological mapping for site selection using the inverse distance weighting (IDW) interpolation method, using as inputs the ANP’s wireline logs information and spatial data generated by our IEE-CCS research group. The resulting map validates the high prospectivity of the black shales of the Irati Formation as reservoirs for CO2 geological storage that comply with both the technical and environmental requirements in the central region of the Paraná Basin, specifi cally in the states of São Paulo, Paraná, and Mato Grosso do Sul.
