Product Description
This high-efficiency glutaraldehyde-based microbiocide is specifically formulated to deliver effective water-based fluid bacterial control in drilling, completion, workover, and packer fluid applications. It offers an economical approach to prevent microbial degradation in fluids containing natural or synthetic polymers such as starch, cellulose, and other biodegradable additives. As a dedicated solution for water-based fluid bacterial control, the product exhibits outstanding performance in eliminating sulfate-reducing bacteria (SRB), acid-producing bacteria (APB), and other detrimental microorganisms that threaten fluid stability and system integrity.
The advanced chemical design of this water-based fluid bacterial control agent ensures fast and thorough microbial inhibition through a targeted biochemical mode of action. Glutaraldehyde actively penetrates bacterial cell membranes and forms covalent bonds with vital proteins and enzymes, disrupting metabolic functions and inhibiting reproduction. This mechanism effectively addresses both free-floating planktonic bacteria and surface-adhered biofilm colonies, ensuring full-system protection.
Applications & Functions
Delivers dependable Water-Based Fluid Bacterial Control during drilling, completion, and well intervention operations
Protects organic additives including viscosifiers and fluid-loss control agents from biodegradation
Applicable in packer fluids, produced water management, and wastewater treatment
Effective in a variety of brine systems including chloride-, bromide-, and formate-based fluids
Suppresses microbial growth in fracturing and completion fluid applications
Reduces microbial-induced corrosion and H₂S generation in water-based systems
Key Benefits
Completely water-miscible for even distribution and fast response
High potency at low dosage levels, offering cost-efficient treatment
Effective against both aerobic and anaerobic bacterial strains
Maintains stability and performance at temperatures up to 400°F (204°C)
Compatible with most water-based drilling and completion fluid compositions
Signcurbs H₂S production by controlling sulfate-reducing bacterial activity
Provides rapid initial kill with extended protective action
Mode of Action
The biocide operates by alkylating key nucleophilic sites-such as amino, carboxyl, and thiol groups-within microbial proteins and enzymes. This cross-linking reaction causes permanent cellular damage, leading to rapid loss of viability. The molecule's amphiphilic nature allows efficient penetration across cell membranes for thorough biocidal activity.
Typical Specifications
Appearance: Clear, light-yellow liquid
Active Ingredient: 45–50% glutaraldehyde
pH Range: 3.1–4.5
Specific Gravity: 1.06
Density: 1.10–1.15 g/cm³ at 20°C

Dosage Recommendations
A standard treatment rate of 0.4 pounds per barrel (ppb) is generally effective under normal conditions. In cases of high microbial load or elevated temperatures, dosage may be increased to 1.0 ppb based on microbial monitoring data. The product may be introduced continuously or as periodic slugs during fluid circulation to sustain active concentration. Regular microbiological assays are advised to tailor treatment schedules and dosages.
Packaging & Storage
Supplied in 25 kg and 200 kg sealed HDPE containers. Store in a cool, ventilated space, protected from direct sunlight and high temperatures.
