Product Description

Product Description

OFREE^® L is ammonium bisulfite liquid form 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^® L scavenger is sensitive to calcium content in the fluid. Hardness must be kept below 2,000ppm. If the pH is above 10, ammonia gas may be released from the drilling fluid. OFREE^® L scavenger is incompatible with glutaraldehyde-base biocides. Biocide may be applied before use, but biocidal activity is lost upon addition of OFREE^® L.

Applications/Functions

• Remove soluble oxygen from water-based drilling fluids and 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 small concentrations

Typical Properties

• Appearance: Yellow liquid
• pH: 5-6
• Specific gravity: 1.30

Recommended Treatment

• A typical treatment range is 0.1-0.5 ppb

Package

• 5 GAL PAIL
