Product Description

Product Description

OFREE^®D is a dry powder oxygen scavenger used for corrosion control or thermal extension of water-based fluids. Applications include oxidative corrosion control in down-hole tubulars and reduction of the conditions that promote thermal degradation of organic materials. OFREE^®D scavenger is suitable for use in fresh water and monovalent brines. Use in divalent brines is not recommended.

Applications/Functions

• Remove soluble oxygen from water-based drilling fluids and monovalent brines

Advantages

• Extends the life of organic polymers and other organic materials, especially at elevated temperatures
• Minimizes oxygen corrosion cell formation
• Lowers mud maintenance costs
• Effective at low concentrations

Typical Properties

• Appearance: White to off-white powder
• pH (1% aqueous solution): 9.4
• Specific gravity: 2.63

Recommended Treatment

• A typical treatment range is 0.1-0.5 ppb

Package

• 25 KG SACK
