Product Description

Product Description

OFREE^®E is a granular sodium erythorbate material oxygen scavenger used to minimize the corrosive effects of soluble oxygen. Dissolved oxygen can be removed from drilling, completion and packer fluids. OFREE^®E works in conjunction with inhibitors, other scavenges and biocides to minimize corrosion and avoid damage to drilling and completion equipment.

Applications/Functions

• Remove soluble oxygen from drilling, completion and packer fluids
• Compatible with freshwater, monovalent and divalent brines
• Used as part of corrosion control systems

Advantages

• Extends the life of organic polymers and other organic materials, especially at elevated temperatures
• Effective at low concentrations
• Rapid removal of dissolved oxygen
• Stable in solution to 250°F
• System stability can be extended up to 500°F

Typical Properties

• Appearance: White granular powder
• Specific gravity: 1.2

Recommended Treatment

• Add 0.2-0.5 ppb to drilling fluids as regular additions
• Add 0.1-0.2 ppb to packer fluids

Package

• 25 KG PAIL
