Dispersants are added to improve the flow properties of the slurry. In particular they will lower the viscosity of the slurry so that turbulence will occur at a lower circulating pressure, thereby reducing the risk of breaking down formations. The most commonly used are:
• Polymers 0.3 – 0.5 lb/sx of cement
• Salt 1 – 16 lb/sx
• Calcium lignosulphanate 0.5 – 1.5 lb/sxg)
