Corrosion inhibitor is a neutralized anionic liquid alkyl phosphate ester. It is designed to prevent oxygen corrosion in water-base, mist and aerated fluids. It is also effective against hydrogen sulfide and carbon dioxide corrosion.
Advantages
- ANCO CI300 A mixes readily with water based fluids.
- An effective corrosion control agent for clear water and brine fluids.
- Cost effective, is required at low concentrations.
Dosages:
Depending upon the expected severity of the corrosive environment ANCO CI300 A corrosion inhibitor can be added directly into the drilling fluid. For mist drilling , ANCO CI300 A corrosion inhibitor should be added to water during makeup.
The amount of ANCO CI300 A corrosion inhibitor in a drilling mud can be monitored with a Petrolite Phosphonate Drop Test Kit. The following chart shows the recommended treatments of ANCO CI300 Acorrosion inhibitor and the residual levels recommended for various corrosive environments.
