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

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