OS OXY SCAV SB - Sodium Bisulphite Liquid Oxygen Scavenger

 

 

Oxygen Scavengers

Oxygen Scavengers are commonly added to drilling 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.
