Seismic 3D Survey Areas for Petroleum Industry Exploration

Polygons depicting the outlines of 3D seismic surveys used for petroleum exploration. The data was extracted from survey reports by the Department of Energy, Environment and Climate Action and is available under a CC-BY-4.0 license. Last updated on 2026-04-09, the polygons illustrate survey extents but definitions vary.

Use Cases

• Map petroleum exploration activity based on survey outlines.
• Analyze regional exploration density based on polygon coverage.
• Visualize historical survey extents for resource assessment planning.
• Integrate survey location data with geological maps for subsurface modeling.

Strengths

• Polygons are extracted from official survey reports.
• Available under a CC-BY-4.0 license.
• Last updated on 2026-04-09.

Limitations

• Polygon definitions are inconsistent; they may represent surface coverage, full fold coverage, or final grid definitions.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
