An April-May 2012 site survey for a semi-submersible rig, assessing environmental and drilling hazards in UK North Sea blocks 13/30a, 13/30b, and 14/26a. The survey was conducted by Nexen Petroleum UK Ltd under licences P300, P310, P811, and P928, with data curated by the British Geological Survey.
Use Cases
- Analyze drilling hazard data from the 2012 survey to identify seabed risks for future rig placements in blocks 13/30a, 13/30b, and 14/26a.
- Correlate environmental survey findings with specific licence areas (P300, P310, P811, P928) to assess regulatory compliance.
- Map the semi-sub rig site survey path to model subsurface conditions for geotechnical engineering.
- Use the DECC Reference Number 2662 to link this survey data with other governmental oil and gas records.
Strengths
- Survey conducted over a defined two-month period (April-May 2012) providing a temporal snapshot.
- Covers three specific UK North Sea blocks (13/30a, 13/30b, 14/26a) for precise spatial analysis.
- Data originates from a major industry operator (Nexen) and is curated by the authoritative British Geological Survey.
- Acquired under four distinct government licences (P300, P310, P811, P928), indicating regulatory oversight.
Limitations
- Core data structure (columns, rows, file formats) is unknown, preventing immediate analytical use.
- Sample data is unavailable, making it impossible to assess data granularity or variable types before acquisition.
- The dataset's size and record count are unspecified, limiting understanding of its scale and completeness.
