Geology and Prospectivity of the Northern Houtman Sub-basin with 2014–15 Seismic Data

A 2014–15 seismic reflection survey (GA-349) by Geoscience Australia was used to reassess the tectonic evolution and petroleum prospectivity of the northern Houtman Sub-basin, offshore Western Australia. The study includes interpretation of the Moho, basement, and major depositional sequences, resulting in a 3D geological model covering the survey area. This work significantly reduced exploration risk in this frontier region of the Perth Basin.

Use Cases

• Modeling crustal structure and tectonic evolution based on seismic interpretation and potential field modeling.
• Assessing petroleum prospectivity based on mapped Permian–Cretaceous stratigraphy and structural architecture.
• Correlating regional seismic stratigraphy to develop a new tectonostratigraphic framework for the basin.

Strengths

• Based on new seismic reflection data acquired in 2014–15 under a government precompetitive data program.
• Includes mapping of up to 16 km of Permian–Cretaceous succession and creation of a 3D geological model.
• Interpretation covers major features including the Moho, basement, and syn-rift sequences.

Limitations

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