National Offshore Petroleum Titles Boundaries from 2003 to 2023

National Offshore Petroleum Titles boundaries are defined in accordance with the Offshore Petroleum and Greenhouse Gas Storage Act 2006. The dataset is based on the Australian Geodetic Datum and uses 5-minute graticular blocks to determine positions. It is derived from well information available through the National Offshore Petroleum Information Management System (NOPIMS).

Use Cases

• Mapping offshore petroleum exploration zones based on the defined 5-minute graticular blocks.
• Analyzing the spatial distribution of energy titles over time based on the 2003-2023 range.
• Supporting regulatory compliance checks using the legal boundaries defined by the OPGGSA 2006.

Strengths

• Boundaries are legally defined by the Offshore Petroleum and Greenhouse Gas Storage Act 2006.
• Covers a 20-year period from the 2003/04 to 2022/23 financial years.
• Spatial positions are determined using the standardized Australian Geodetic Datum.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic or regulatory bias inherent to the source jurisdiction.
