BICARBONATE OF SODA
BICARBONATE OF SODA (NaHCO₃) is used primarily to remove calcium contamination from water-based drilling fluids following cementing operations.
Application
BICARBONATE OF SODA (NaHCO₃) is used as a calcium sequester (water softener). Bound Calcium is precipitated out of solution thereby removing it from the system. BICARBONATE OF SODA also acts a a pH control, reducing the pH of the system.
Advantages
- Primarily used to prevent or treat calcium contamination in water-based drilling fluids
- Effectively and economically treats out calcium ions by removing them as an insoluble carbonate
- Will reduce the pH of the drilling fluid
