Introduction

O₂ Scavenger is ammonium bisulfite liquid form 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. Oxygen Scavenger scavenger is sensitive to calcium content in the fluid. Hardness must be kept below 2000 ppm. If the pH is above 10, ammonia gas may be released from the drilling fluid. Oxygen Scavenger scavenger is incompatible with glutaraldehyde-base biocides. Biocide may be applied before use, but biocidal activity is lost upon addition of Oxygen Scavenger.
