Western Australia Petroleum Exploration Wells Onshore and Offshore

Western Australia's reference system for petroleum exploration and development wells, including both onshore and offshore locations. The dataset is managed by the Department of Energy, Mines, Industry Regulation and Safety, with onshore wells updated regularly and offshore records prior to 2012 included.

Use Cases

• Map well locations and types across Western Australia for spatial resource analysis
• Analyze historical offshore well activity prior to 1 January 2012 for trend studies
• Integrate onshore well geometry with other geological datasets for exploration planning

Strengths

• Managed by the authoritative state department for energy and resources
• Includes both onshore and historical offshore well locations
• Available in multiple GIS formats including SHP, KML, and API services

Limitations

• Offshore well data is not current beyond 1 January 2012 and relies on ad-hoc updates from NOPTA
• Specific data volume, row count, and column schema are unknown
• Potential spatial or temporal gaps exist due to split jurisdiction post-2012
