Feature And Benefits

SODIUM SILICATE forms a gel by reacting with formation waters, and prevents the pore pressures transmission. SODIUM SILICATE has a synergistic effect of improved shale inhibition and better viscosity control of the fluid when used in conjunction with a salt. Therefore, it is advisable to use potassium chloride with sodium silicate. SODIUM SILICATE is effective at temperature up to 275 ⁰F (135 ⁰C).

Product Function

SODIUM SILICATE improves the chemical inhibition of reactive shale in water based fluids from fresh water to salt saturated.

Recommended treatment

SODIUM SILICATE can be added at 5% by volume of the liquid phase to enhance inhibition. This is the minimum recommended concentration. Due to rapid depletion of silica (SiO₂) from contamination e.g. Ca²⁺ or CO₂ when drilling certain formations, 12% by volume SODIUM SILICATE in the liquid phase (50 g/l SiO₂) is recommended as initial treatment.

Shipping References

Transportation of SODIUM SILICATE is not restricted by any regulatory agency.

Handling Recommendations

SODIUM SILICATE solution maybe irritating to skin and eyes due to its higher alkalinity. Utilize normal precautions for employee protection when handling chemical products. Utilize appropriate respirator, gloves, goggles and apron. Refer to the Material Safety Data Sheet (MSDS) for this product prior to use.

Standard Packing

SODIUM SILICATE is packaged in 280 kgs net HDPE drum.
