Oxygen Scavenger
Overview
This series of Oxygen Scavengers is designed to effectively remove dissolved oxygen from drilling fluids and oilfield water systems. Through rapid chemical reaction, they reduce oxygen content at the source, preventing oxygen-induced corrosion and protecting the integrity of metal equipment, pipelines, and downhole tools. The products are widely used in drilling, completion, and water injection operations.

Hydrogen Sulfide Scavenger
Overview
This series of Hydrogen Sulfide Scavengers is designed to effectively remove and control hydrogen sulfide (H₂S) and reactive sulfur species in drilling and oilfield operations. Through chemical capture, oxidation, or conversion mechanisms, toxic sulfides are transformed into stable, non-hazardous or low-toxicity forms, ensuring operational safety, personnel protection, and equipment integrity. The products are suitable for both water-based drilling fluids and oilfield water systems.
Key Functions
- Rapid removal of hydrogen sulfide (H₂S) from drilling fluids and systems
- Mitigation of toxicity risks to personnel and equipment
- Reduction of sulfide-induced corrosion (sour corrosion)
- Prevention of drilling fluid degradation caused by sulfur contamination
- Enhancement of well control and operational safety
Features
- Fast reaction rate with high desulfurization efficiency
- Effective in high H₂S and complex formation conditions
- Good compatibility with drilling fluid systems
- Stable performance under high temperature and high salinity
- Available in various types (metal salts, aldehyde-based, oxidizing agents, blended systems)
- Low-toxicity and environmentally friendly formulations available
Applications
- Drilling operations in H₂S-bearing formations
- Sour gas and high-sulfur oil & gas wells
- H₂S control in drilling fluid and circulation systems
- Oilfield surface handling and storage systems
- Sour service corrosion prevention scenarios
