Greenhouse Gas Assessment Permits: Offshore Petroleum Titles in Australian Waters

A web service from the National Offshore Petroleum Titles Administrator (NOPTA) regulates offshore petroleum and greenhouse gas storage titles in Commonwealth waters. The service contains permit and title boundaries based on 5-minute graticular blocks using the Australian Geodetic Datum, granted under the Offshore Petroleum Greenhouse Gas Storage Act 2006. The data was last updated on 2026-03-25.

Use Cases

• Mapping offshore petroleum title boundaries based on the 5-minute graticular block system.
• Analyzing spatial distribution of greenhouse gas storage permits under the 2006 Act.
• Regulatory compliance checks for activities in Commonwealth waters beyond 3 nautical miles.
• Integrating permit data with other marine spatial planning layers for environmental assessments.

Strengths

• Data is sourced from the authoritative regulatory body, the National Offshore Petroleum Titles Administrator (NOPTA).
• Boundaries are defined using a standardized 5-minute graticular block system based on the Australian Geodetic Datum.
• Last updated on 2026-03-25, indicating recent maintenance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is provided only as a WMS web service, which may limit direct analysis compared to downloadable files.
• Row count and specific attribute details are unknown, which may limit suitability assessment.
