ANCO CI300: A Unique Corrosion Inhibitor

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.
