Soda Ash
Catalog NO.: AIMRSE-CHM-ADD-009 Manufacturer PN: CHM-CRB-SOD
• Increases pH with a small dosage.
Remove dissolved calcium ions from mud to address cement contamination.
Sodium carbonate, chemical formula: Na₂CO₃, commonly known as “soda ash,” is frequently used to remove calcium ions dissolved in drilling fluids. Sodium carbonate is weakly alkaline and dissolves in solution to form sodium ions and carbonate ions. Calcium ions, commonly present in drilling water and formations, cause mud flocculation, leading to increased mud viscosity, higher shear stress, and accelerated fluid loss. These issues can be addressed by using sodium carbonate.

| Recommended Dosage | 2.65 kg/m³ is required to treat every 1 kg/m³ of dissolved calcium ions; in case of severe cement erosion, sodium carbonate should not be used for treatment, as excessive addition of sodium carbonate will lead to carbonate contamination. |
