Improved expansion in low-temperature environments
Halliburton's MicroBond expanding additive uses a crystalline composition to improve the expansion properties of cement in low-temperature environments. MicroBond additive is highly effective with low-strength cements, such as 50/50 Pozmix® cement blends.
MicroBond additive promotes optimum expansion at bottomhole temperatures (BHTs) below 170°F (76.6°C), and adequate expansion is available at BHTs below 130°F (54°C). At temperatures below 115°F (46°C), salt can be added to improve the performance of the additive.
MicroBond additive can provide the following benefits:
- Compatible with all Portland cements, regardless of tricalcium aluminate content
- Not classified as hazardous waste by the Environmental Protection Agency (EPA)
- Has a shelf-life of up to 24 months
