Browse Basin Cretaceous and Cenozoic Surface Grids for CO2 Storage Assessment

Twelve regional depth surface grids and fault maps for the Browse Basin offshore northwest Australia, produced by Geoscience Australia. The data pack includes grids for key Cretaceous and Cenozoic horizons and two fault population shapefiles, derived from 60 wells and 26 seismic surveys. This output supports regional assessments of geological CO2 storage potential and petroleum prospectivity.

Use Cases

• Modeling subsurface CO2 storage capacity based on regional depth surface grids.
• Assessing petroleum prospectivity using interpreted fault maps and horizon surfaces.
• Conducting basin evolution and sequence stratigraphy analysis based on the updated tectonostratigraphic framework.
• Integrating depth-converted surfaces into 3D geological or petroleum systems models.

Strengths

• Includes 12 regional depth surface grids for specific Cretaceous and Cenozoic horizons.
• Interpretation is based on data from 60 wells and 26 regional 2D and 3D seismic surveys.
• Outputs include both surface grids and fault maps (polygon and horizon fault boundaries).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
