Silicalite™ Cement Additive

Silicalite™ cement additive is made from a finely divided, high surface-area silica.  It can be used as an extender for lightweight cements and a compressive-strength enhancer for low-temperature, lightweight cements. This product also imparts thixotropy to some cement slurries. Silicalite additive can be used in wells with bottomhole circulating temperatures (BHCTs) between 50°F and 500°F (10°C and 260°C).

Silicalite additive is available as a powder, a liquid, a Pozmix® cement blend, or a compacted material. Compacted Silicalite additive does not have the same performance properties as the liquid or powder forms. Therefore, designs including compacted Silicalite additive should be subjected to laboratory testing before being used in the field.
