Magnesium Oxide

it is used to provide alkalinity control for all water based systems and is compatible with freshwater, brines, and brine polymer systems. it dissolves in water to provide a pH of approximately 10.3.  This creates a pH buffer that is safer to use than caustic soda. It can be used to increase the pH of aqueous systems and can also be used as an alternative to lime for treatment of carbon dioxide contamination. Its ability to act as a pH buffer results in it increasing the thermal stability of polymers.

Recommended Treatment
Typical treatment range of magnesium oxide is 0.3 – 5.7 kg / m³ (0.1 – 2.0 lb / bbl) up to 8.6 kg / m³ (3 lb / bbl) may be used in drill-in fluids. Pilot tests should be conducted in order to determine correct treatment.
