Fluid Loss Control Agent
Fluid loss control agent is an important cement additive that reduces the fluid loss from slurry. When cement slurry is pumped into the well, it comes across several open formations. If a formation is porous and permeable, the aqueous phase of the slurry escapes into the formation under pumping pressure. This changes the rheological properties of the slurry due to improper solid and liquid fraction. If the loss of fluid is not controlled, the slurry could become too thick and eventually unpumpable causing failure of cement job.
