Microbial Diversity in an Offshore Oil Reservoir: Effects of Water Breakthrough

A 2026 study by Armando Alibrandi investigates microbial communities in the Edvard Grieg oil reservoir offshore Norway. The dataset includes 16S rRNA gene and metagenomic sequencing data from produced fluids, production water, and injection water samples. It characterizes low-diversity communities dominated by thermophilic, anaerobic, and halotolerant taxa, with shifts linked to water breakthrough.

Use Cases

• Monitoring shifts in sulfate-reducing bacteria populations based on sequencing data from production fluids.
• Identifying regional heterogeneity in microbial community composition based on samples from specific wells (e.g., A07, A13).
• Developing cost-effective microbial signature tools for oil reservoir process monitoring based on comparisons between fluid and water samples.

Strengths

• Dataset is 8.4 MB, indicating a focused and manageable size for analysis.
• Sequencing data covers multiple sample types: produced fluids, production water, and injection water.
• Specific geographic and reservoir context is provided: the Edvard Grieg oil reservoir offshore Norway.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The primary data file is a DOCX format, which may require extraction or conversion for analysis.
