February 2014 site survey documents drilling hazards and debris clearance for the Sparrowhawk South/Firecrest semi-sub rig. The survey was conducted by Nexen Petroleum UK Ltd across North Sea blocks 21/2a, 21/3a, and 21/3f under five specific licences.
Use Cases
- Map drilling hazard locations identified in the 2014 survey for risk assessment planning.
- Analyze debris clearance data to evaluate pre-drilling site preparation requirements.
- Correlate survey findings with specific licence areas P244, P1560, P118, P741, and P1256 for regulatory compliance review.
- Use block numbers 21/2a, 21/3a, and 21/3f to geolocate survey results within the North Sea.
Strengths
- Survey conducted by the authoritative British Geological Survey (BGS).
- Precise temporal coverage from February to March 2014.
- Clear spatial definition across three North Sea blocks: 21/2a, 21/3a, and 21/3f.
- Specific operational context for a semi-sub rig named Sparrowhawk South/Firecrest.
Limitations
- Core data structure (columns, rows, sample) is unknown, limiting analytical readiness.
- File format and dataset size are unspecified, complicating integration workflows.
- Lack of sample data prevents assessment of data granularity and variable types.
