21CXRM Phase 2: East Shetland Platform and SW Approaches Petroleum Systems Study

Integrated petroleum systems studies and seep evaluations of the East Shetland Platform and SW Approaches area of the UK Continental Shelf. The studies were completed in Q3 2018 as an industry collaboration led by APT under contract to the North Sea Transition Authority. The work addresses questions around the existence and effectiveness of petroleum systems in these relatively under-explored areas.

Use Cases

• Assessing Devonian source rock potential based on geochemical analysis and biomarker studies.
• Modeling hydrocarbon generation and migration timing for play risk assessment in the East Shetland Platform.
• Correlating oil shows to Early Jurassic source rocks in the SW Approaches area.
• Evaluating basin prospectivity using integrated geochemistry and thermo-chronology datasets.

Strengths

• Study is based on a fully integrated, very high-quality geochemistry and thermo-chronology dataset.
• Analysis includes age-diagnostic biomarker studies allowing for oil-source correlation attempts.
• Work was conducted as an industry collaboration under the 21CXRM initiative, suggesting peer-reviewed methodology.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
