ABSTRACT:
A composition suitable for scavenging oxygen from aqueous systems, for example those used in well drilling, is provided which comprises a mixture of an oxygen-reactive sulfite and/or bisulfite (sulfite component) and an amount of iron oxide particles sufficient to catalyze the reaction between oxygen and the sulfite component. These particles have certain properties as further described herein. These compositions also serve as corrosion inhibitors in aqueous systems, such as drilling muds, to protect steel components from corrosion. A method is also provided for using such compositions in aqueous systems to scavenge oxygen from such systems, and also H.sub.2 S, if present.
