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
