Description
Geoscience Australia's study reassesses the tectonic evolution and petroleum prospectivity of the northern Houtman Sub-basin using seismic reflection data acquired in 2014–15. The interpretation enabled mapping of the Moho, basement, and major depositional sequences, and the creation of a 3D geological model covering the survey area. This work has 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 depositional sequences and structural architecture.
Correlating regional seismic stratigraphy to develop a new tectonostratigraphic framework.
Identifying exploration targets based on mapped half-graben structures and sediment thickness variations.
Strengths
Based on new seismic reflection data (GA-349) acquired in 2014–15 under a government precompetitive data program.
Includes a 3D geological model and mapping of sequences up to 16 km thick, providing detailed subsurface interpretation.
Specifically reduced exploration risk in the northern Houtman Sub-basin, a previously under-explored frontier.
Limitations
Data is provided as DOCX and PDF documents; the underlying raw seismic or model data files are not specified.
Column-level documentation is absent; field semantics must be inferred after download.
Row count is unknown, which may limit suitability assessment for quantitative analysis.
