Microbial Diversity in the Edvard Grieg Oil Reservoir, Offshore Norway

16S rRNA gene and metagenomic sequencing data from produced fluids, production water, and injection water samples reveals microbial community shifts in a petroleum reservoir. The dataset, 1.5 MB in size and last updated in March 2026, was created by Armando Alibrandi and shared under a CC-BY-4.0 license. It shows clear regional heterogeneity in community composition, characterized by overall low diversity dominated by thermophilic, anaerobic, and halotolerant taxa.

Use Cases

• Monitoring shifts in sulfate-reducing bacteria populations based on water breakthrough events.
• Identifying regional heterogeneity in microbial community composition based on sample location (e.g., wells A13, A17, A18, A19, A07).
• Developing cost-effective microbial signature tools for oil reservoir integrity monitoring based on sequence data from production fluids and water samples.
• Studying the prevalence of specific genera like Thermoanaerobacter and Thermococcus under thermophilic, anaerobic, and halotolerant conditions.

Strengths

• Data includes 16S rRNA gene and metagenomic sequencing, providing genetic-level detail.
• Samples are from multiple sources: produced fluids, production water, and injection water from specific wells (A13, A17, A18, A19, A07).
• Dataset is shared under a permissive CC-BY-4.0 license.

Limitations

• Row count and column-level documentation are unknown, limiting suitability assessment.
• The 1.5 MB file size suggests a relatively small dataset, which may limit statistical power for some analyses.
• Description metadata is limited; actual data quality requires manual inspection after download.
