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.

Product Information

OS COR 420 is a formulated product containing a mixture of amines in a water carrier solvent. OS COR 420 is used as a general drilling fluid inhibitor and for applications involving packer fluids and completions fluids.

Typical Physical Properties

Appearance   –   Brown Liquid                                   

pH   –   10.0 – 12.5

S.G. @ 20°C   –   0.98 – 1.10                             

Flash Point (PMCC)   –   Greater than 60oC

Solubility   –   Water and brine

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.
