Microbiological fouling in oil and gas production systems can result in significant financial loss and plant down time if not monitored and remediated efficiently. Proliferation of sulphatereducing bacteria (SRB) and sulphate-reducing archaea (SRA) can cause microbially influenced corrosion (MIC) in pipelines and production vessels, or reservoir souring and loss of injectivety due to clogging of pore space.
NECE have the capabilities & multi-skilled personnel to combine corrosion monitoring with full microbiological surveys through their in house microbiology service division. This allows monitoring of the sessile and planktonic bacterial populations which are likely to develop within oil and gas production systems. This combined approach provides valuable monitoring data for assessing risks and preventing failures and unplanned shutdowns.
- Swabbing & planktonic sampling in all critical systems

- Bacterial analysis of utility systems (diesel, firewater, cargo tanks etc.)
- Monthly sample analysis / incubation and full interpretation
- Data correlation and interpretation (pitting rate / coupon morphology)
- Remedial actions / recommendations
- Evaluation of biocide efficiency
- Biocide dosage solutions (bridles, semi-automatic systems)
- Microbiology strategy implementation
- MIC failure investigations and analysis
- Side-stream facilities
