Northern Houtman Sub-basin Geology and Petroleum Prospectivity from 2014–15 Seismic Data

New seismic reflection data from 2014–15 (GA-349) was used to reassess the tectonic evolution and petroleum prospectivity of the northern Houtman Sub-basin. Interpretation enabled mapping of the Moho, basement, and major sequences, resulting in a 3D geological model covering the survey area. The study significantly reduced exploration risk in this frontier region offshore Western Australia.

Use Cases

• Modeling crustal structure based on seismic interpretation and potential field modeling described in the study
• Assessing petroleum prospectivity risk based on the mapped Permian–Cretaceous tectonostratigraphic framework
• Correlating regional seismic stratigraphy across the northern Perth Basin using the new framework
• Analyzing the distribution and thickness of key formations like the Lower Triassic Kockatea Shale

Strengths

• Based on new seismic reflection data acquired in 2014–15 under a government precompetitive data program
• Includes a 3D geological model covering the survey area
• Maps up to 16 km of Permian–Cretaceous succession and a 2–3 km thick pre-rift section

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data is delivered as DOCX and PDF files, which may require extraction for computational analysis
