Microblock® preventing strenght retrogression and gas migration at elevated temperatures
Microblock® is a high weighted silica dispersion solution developed as a viable alternative to the silica/cement dry blends.
This silica dispersion complies with the restricted North Sea offshore regulation and is a safer solution. Microblock® offers additional benefits by preventing gas migration, improving early compressive strength, and controlling filtration and rheological properties. The extreme fine particles of Microblock® works as a packing agent between other larger particles. Regardless of the cement slurry density or downhole temperatures, Microblock® will prevent settling and free water by binding excess water.
