HK - OXYGEN SCAVENGER

HK - OXYGEN SCAVENGER

An ammonium bisulfite solution used to remove entrained oxygen from drilling and completion fluids. The product is injected at the pump suction on a continuous basis to Minimize atmospheric contact. It functions as a corrosion inhibitor by removing Oxygen from the drilling or completion fluid while circulating.

Advantages

• Removes oxygen from water to prevent corrosion in drill strings.
• Injected continuously at the pump suction with minimal atmospheric contact.
• Monitored using an excess sulfite test at the flowline. Initial injection rate: 1-2.5 gal (3.8-9.5 L) per hour.
• Injection rate adjusted based on sulfite test results.
• Target excess sulfite content: 100-300 mg/L at the flowline.
• Corrosion inhibitor often used with it.
• Corrosion rings may be used to monitor corrosion rates over time.
