Mentelle Basin Seismic and Geophysical Survey Data for Petroleum Prospectivity

Geoscience Australia acquired 2,570 km of industry-standard seismic, gravity, and magnetic data in the Mentelle Basin during the 2008-09 Southwest Margins survey. The dataset supports the petroleum prospectivity assessment for the basin's first acreage release in 2010. The data was published by the Australian Ocean Data Network and last updated in June 2026.

Use Cases

• Mapping subsurface structures and supersequences based on interpreted seismic data.
• Assessing petroleum system potential based on identified source rocks, reservoirs, and seals.
• Evaluating a range of play types, including faulted anticlines and stratigraphic traps, mentioned in the description.

Strengths

• Includes 2,570 km of industry-standard seismic data.
• Covers a large, defined sedimentary basin area of 36,000 square meters.
• Data acquisition was conducted by the national geoscience authority, Geoscience Australia.

Limitations

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