CGG Additional JDWLs: Joined Digital Well Logs for UKCS Exploration

UK Continental Shelf (UKCS) exploration and appraisal wells are covered by this collection of joined digital well logs, deviation surveys, and time-depth curves. The North Sea Transition Authority purchased and released this data, which includes approximately 900 wells from an initial purchase and additional wells released in support of the 31st Frontier Licensing Round. The dataset was last updated in June 2026.

Use Cases

• Analyze subsurface rock properties based on joined digital well logs.
• Model wellbore trajectories based on deviation survey data.
• Perform time-depth conversion for seismic interpretation based on time-depth curves.
• Support frontier exploration licensing rounds based on the dataset's stated purpose.

Strengths

• Covers approximately 900 UKCS exploration and appraisal wells.
• Includes multiple data types: joined digital well logs, deviation surveys, and time-depth curves.
• Released with full publication rights by the NSTA.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified despite the 2026 update date.
