- It has a high compressive strength at low density.
- It has a low porosity and permeability.
- It can improve sedimentation stability, reduce water loss, and reduce the free water.
- It has a good perforation performance.
- When slurry density fluctuations, its performance is essentially the same, or even a small change.

Enhancer Agent for Oil Well Cement
Product Description :
This product ( G211 ) plays down the impact of the density on the grout and cement performance. This technology is based on the theoretical basis of choice of optimum ratio and the mixture with a suitable specific gravity and with different particle size distribution. Composed of cement, beads, ultra-fine silica fume, slag, fly ash, micro silica, silicon straw, fine cement, silica fume, etc., plus series admixtures ( retarder, dispersants, fluid loss agent ).
