Nov 06, 2016 – Start with a high yet low FL control (+/- 250 ml/30min). This can probably be achieved just with cement and dispersant. Sometimes increasing the density 1 or 2 points above neat cement (above 15,8 ppg for class G or 16,2 ppg for class H) helps, e.g., 15,9 or 16 ppg for class G (cement itself is the best FL control additive)

Dec 05, 2017 The importance of proper cement blending is evident when one considers that for some cement systems as little as 20 lbm of an additive is blended with 20,000 lbm of cement. Nonuniform additive blending (e.g., small variations in additive concentrations) or incorrect additive concentration results in improper slurry performance in the wellbore
