OS COR 420 - Drilling Corrosion Inhibitor

 

 

Corrosion

Oilfield tubulars and other downhole equipment must be protected from all types of corrosion when exposed to well fluids of any kind. Surface corrosion is a common cause of tubular failures and must be controlled at all times. Corrosion inhibitors should be applied to all fluids that have the potential to create a corrosive environment.

Advantages  

OS COR 420 can be used with drilling fluids and their associated solids content as well as with clear fluids for completion/workover applications. OS COR 420 is designed to have a high solubility in sodium chloride and calcium chloride brines. OS COR 420 will not interfere with normal drilling fluid properties.

 

Application  

For use as a standard drilling inhibitor, to prevent corrosion of the drill string, it is recommended to be used at 2% of the drilling fluid volume. 

For use in clear fluids it is recommended to be added at 0.5-1.0% of the fluid volume.

 

Packaging

OS COR 420 is packaged in 55 US gallon drums.
