OS BRI-SCAV - Powder Oxygen Scavenger

 

 

Oxygen Scavengers

Oxygen Scavengers are commonly added to drilling fluids, workover fluids and completion fluids to mitigate the adverse effects of dissolved oxygen in downhole environments. Dissolved oxygen can radically decompose polymeric additives in the drilling fluid and can corrode the metal casing and the drill pipe.

  

Product Information 

OS BRI-SCAV is a non-sulphite oxygen scavenger designed to eliminate oxygen which is a key contributor to corrosion. OS BRI-SCAV is mainly used in low density clear brine workover and completion fluids containing monovalent ions such as potassium and sodium. We recommend that this product is not used with chrome resistant alloy metallurgy.

 

OS BRI-SCAV rapidly removes dissolved oxygen and is efficient at low concentrations.
