Spatial database and QGIS project for CO2 storage site screening in the Campos Basin, (case study) offshore Brazil

This dataset contains the derivative products generated in the study "A transferable workflow for preliminary CO2 geological storage site screening using legacy seismic and well data" (manuscript under review, International Journal of Greenhouse Gas Control). The deposit includes: - study.gpkg: GeoPackage containing vector and raster layers for structural interpretation, seismic footprints, well locations, and basin boundaries in EPSG:31984 (SIRGAS 2000 / UTM zone 24S). - study.qgz: QGIS project file with pre-configured symbology, layouts, and layer organization to support reproduction of the structural models. The underlying seismic and well data are owned by the Brazilian State and available upon request from the ANP/BDEP (https://www.gov.br/anp).
