A North Sea site survey for oil and gas drilling hazards and environmental assessment, conducted by Nexen Petroleum UK Ltd between November 2011 and February 2012. The survey traversed UK Continental Shelf blocks 20/7, 20/2a, and 20/8a, and was acquired using a semi-submersible rig.
Use Cases
- Analyze drilling hazard data from the semi-sub rig site survey to assess seabed stability for the Bardolph field.
- Map environmental baseline conditions across UK blocks 20/7, 20/2a, and 20/8a for regulatory compliance reporting.
- Integrate survey findings with other datasets using the DECC Reference Number 2639 for a regional subsurface hazard assessment.
Strengths
- Survey conducted over a defined 4-month period from November 2011 to February 2012.
- Geographic scope is precisely documented across three UK Continental Shelf blocks.
- Data originates from the authoritative British Geological Survey (BGS).
Limitations
- The specific data columns, row count, and file formats are unknown, limiting immediate analytical utility.
- Data is over a decade old and may not reflect current seabed or environmental conditions.
