Description
SDM CIDE 50 is a highly effective quaternary ammonium compound-based biocide used in various oilfield applications. It is very effective against bacteria, fungi, algae, and other types of organisms. It is completely soluble in water.
Physical Properties
- Appearance.................... Colorless to yellow liquid
- Solubility....... Soluble in water, glycol and alcohol
- pH (5% solution)...................................... 6.0 – 8.5
- Flash point (°C)............................................ >100.0
- Specific gravity (25°C) .......................... 0.95 – 1.00
Applications
SDM CIDE 50 can be used in all types of water-based mud and low-salinity brine systems. It is used to treat makeup water in water-based systems to prevent bacterial attacks on polymers, which can affect the system's properties. It is also used in completion brines and packer fluids to reduce corrosion-related bacterial activity.
SDM CIDE 50 is very effective at low dosages. Recommended treatment is usually 0.05 – 0.1% v/v. Highly contaminated water may require a higher dosage.
SDM CIDE 50 has a long-term effect; however, periodic treatment may be needed. Bacterial activity can be monitored using bacterial culture tests methods in the laboratory.
Presentation / Packaging
SDM CIDE 50 is packaged in 55-gal HDPE drums.
