Bond Improvement Agents

Microsilica prevents high-temperature strength retrogression, controls lost circulation, and assists in preventing gas migration. Furthermore, it assists in fluid loss control.

The effectiveness of casing string cementation in oil & gas wells depends on the composition and properties of cement slurries.

The properties of cements are often modified to meet the demands of a particular well application. These modifications are accomplished by additives that effectively alter the hydration chemistry. To the contrary of many other chemicals, Microsilica reacts with the raw components of Portland cement giving it extra strength and lower permeability.

Due to its sub-micron size, Microsilica particles play a physical role in improving the rheology and stability of cement slurries.

The packing of the cementitious slurry is improved and gas percolation in the still liquid cement sheath is reduced allowing effective gas-migration control when used with a fluid control additive.
