A site survey for an oil and gas semi-submersible rig, conducted in March 2013 under multiple UK licences. The survey covers drilling hazards, environmental conditions, and debris clearance across blocks 14/26, 14/26a, and 20/1 in the North Sea. It was acquired by Nexen Petroleum UK Ltd and archived by the British Geological Survey.
Use Cases
- Analyze drilling hazard data from the March 2013 survey to assess site-specific risks for rig operations.
- Map environmental survey results across licences P300, P1611, P252, P928, and P1779 for regulatory compliance review.
- Use debris clearance records to plan and cost future seabed preparation activities in blocks 14/26, 14/26a, and 20/1.
Strengths
- Survey conducted in March 2013, providing a specific temporal snapshot.
- Covers multiple UK offshore licences (P300, P1611, P252, P928, P1779).
- Geographically scoped to three specific North Sea blocks: 14/26, 14/26a, and 20/1.
Limitations
- Column structure and sample data are unavailable, hindering immediate technical analysis.
- Data is over a decade old and may not reflect current seabed or environmental conditions.
- Specific file formats, size, and row counts are unknown, complicating integration planning.
