Using high-quality field data from oil, water and gas sampling and analysis, a qualitative risk assessment and quantitative H2S production prediction and forecasting is undertaken to understand the risk of the reservoir turning sour. Mitigation strategies are then evaluated and executed field wide.

  • Reservoir souring predictive modelling
  • Mitigation strategies
  • Biocide trial and efficacy
  • Onsite biocide optimization
  • Nitrate trial
  • Fixed Film Upflow Bioreactor (FFUBR)
  • H2S Scavenger trial (HPHT)
  • Surface solutions – H2S Scavenging, Scrubbing and Reduction (SSR)
  • Oilfield Microbiology

With our experience in Microbiologically Influenced Corrosion (MIC), reservoir souring, H2S mapping, and bacterial monitoring, solutions can be catered to meet the needs of the customer and further provide insights into the health of the reservoir and assets.
Based on water chemistry and process data, the impact of corrosion on pipelines and tubing can be predicted and assessed so that integrity engineers have a better understanding on mitigation strategies in controlling corrosion as well as corrosion inhibitor efficacy in their assets.
We provide onsite chemical optimization for corrosion inhibitors, biocides, and oxygen scavengers. This is to ensure that the chemicals involved are not under-dosed and that the desired results are obtained.
