Western Australia Petroleum Exploration 3D Seismic Survey Polygons

DMIRS-035 is a reference system for petroleum exploration 3D seismic surveys in Western Australia. The dataset is updated regularly and managed by the Department of Energy, Mines, Industry Regulation and Safety.

Use Cases

• Analyze spatial distribution of petroleum exploration 3D seismic survey polygons for regional resource assessment.
• Track temporal updates of survey polygons to monitor exploration activity in Western Australia.
• Integrate survey polygon data with other geological datasets for subsurface modeling.

Strengths

• Managed by the authoritative state department (Department of Energy, Mines, Industry Regulation and Safety).
• Updated on a regular basis, with a last update recorded in 2026.
• Available in multiple geospatial formats including GDB, SHP, and WFS for interoperability.

Limitations

• Unknown row count and column structure limits immediate analytical planning.
• Sample data is unavailable, preventing preview of data schema and quality.
• Offshore data since 2012 is managed by a separate system (NOPTA/NOPIMS), creating a potential data discontinuity.
