Control a broad spectrum of bacteria

Our microbiocides are proven to control a broad spectrum of anaerobic and aerobic bacteria, particularly sulfate-reducing bacteria (SRB), for water injection and produced-water systems. These products work through direct microbiological activity and by modifying the environment to prevent bacteriological activity.

Schlumberger pioneered nitrate application to prevent water reservoir souring by shifting the consortia from SRB to nitrogen-reducing bacteria (NRB).

Microbiocides fall into three fundamental categories:

  • aldehydes that penetrate the cell and denature the protein
  • surfactants that coat the cell membrane, blocking the passage of nutrients across the cell wall
  • oxidizing biocides that lyse (destroy) the cell wall.

Enhance effectiveness through monitoring programs

Product applications are supported by robust monitoring programs facilitated by our Microbial InstaCheck real-time bacteria measurement, monitoring, and control service. This comprehensive service is a rapid, cost-effective, easy-to-use, portable onsite analysis program that affords full evaluation of field microbial control strategy.

Utilizing both new and established bacteria enumeration techniques coupled with proprietary ChemWatcher integrated chemical management system, the Microbial InstaCheck service delivers informed, real-time decisions regarding microbiological control strategies to drive operational efficiency, safety, and performance.

Location of bacteria populations is readily established the effectiveness of current biocide applications confirmed, and future bacteria control strategy optimized.
