Oxygen has long been recognized as one of the most troublesome contaminants of oilfield waters. Although in rare cases it can be produced from oil bearing zones, most often it enters a system through surface operations. The general and pitting corrosion rates, as well as undissolved solids and aerobic bacteria, can be reduced by effective oxygen removal (1,5). Scavengers are designed to remove dissolved oxygen from water and are most economical when encountering lower levels of oxygen or if smaller amounts of fluids are to be scavenged. Larger amounts of oxygen and/or fluids may require the use of both stripping and scavenging (5). The oxygen scavengers common in the oilfield are SO2 (sulfur dioxide) and sulfites.
