DosFL™ SP-20 Fluid Loss Control Agent

Built for the Integrity of Your Well

DosFL™ SP-20 Fluid Loss Control Agent

In primary cementing the loss of fluid can eventuate in the premature gelation, consequently, it causes the bridging of the annular space between the permeable formation or zone and the pipe string that prevents the cement from being placed over the entire length of the well. Fluid loss control agents are added to the cement to limit the loss of water from a slurry into the permeable zones.

We provide remarkable additives to help engineers address the industry’s most pervasive types of fluid loss. One of our recommendations is DosFL™ SP-20 that is applicable for all types of cement slurries and conditions. Moreover, this product has a viscosifying effect on the slurry after mixing and can be dissolved in mixed water or dry blended with the cement to provide filtration control properties for a variety of circumstances.

DOSAS’ fluid loss control additives can be used in combination with gas migration control additives, retarders, and dispersants.

Application temperature: Up to 230 °C.



  • Significant fluid loss control at low concentration.
  • Easily achieving to low free fluid.
  • Synergy with retarders.
  • Highest values are observed at high temperatures in the presence of DosR™ EZ-HT Retarder.
