Biocide

Biocide is a highly effective antimicrobial chemical used in drilling, completion, and production fluid systems to control microbial contamination and maintain fluid performance.

Microbial activity in oilfield systems—especially from sulfate-reducing bacteria (SRB)—can lead to serious operational problems including:

• Hydrogen sulfide (H₂S) generation
• Biofilm formation
• Fluid degradation
• Loss of viscosity and rheological stability
• Microbial-induced corrosion (MIC)

Biocide works by disrupting microbial cell membranes, denaturing proteins, and destroying cellular structures, thereby rapidly eliminating harmful microorganisms and preserving system integrity.

The product is highly effective in freshwater, seawater, and brine systems, making it suitable for a wide range of drilling and production applications. Its thermal stability also ensures reliable performance under elevated downhole temperatures.
