M-I SWACO provides oxygen and sulfide scavengers in addition to corrosion control additives for various water-based drilling fluid systems. Surface as well as downhole corrosive gases can be treated to prevent failure of drilling tools and drillstring tubulars. Corrosion rates should be monitored throughout the drilling program with corrosion rings.

Case Study Pakistan: Conqor 404 Prevents Severe Drill Pipe Corrosion in Deep Well

As with most wells, M-I SWACO uses corrosion coupons during this particular project to monitor the corrosion rate while drilling to ensure it remains under an acceptable limit (30 lb/ft2/yr), which was totally unacceptable.
