- Excellent inhibition capability, can restrain the hydration, expansion and dispersion of shale and cuttings, keep bore hole stability.
- With perfect fluid loss control effectivity, good resistance to saturated calcium and salt it can be used in freshwater, seawater and saturated saltwater drilling fluids.
- It is compatible with other drilling fluid additives. While being easily applicable and maintained it requires only low dosages(2%) and thus the cost factor is attractive.
