Product Highlights: Selvol™ Premiol DWC50 is a fluid loss control additive that was designed specifically for high-temperature applications.

Selvol™ Premiol DWC50 is a nonretarding powder that provides fluid-loss control for cement slurries at temperatures ranging up to 300°F.

Typical Selvol™ Premiol DWC50 concentrations range from 0.5% to 1.5% by weight of cement (%bwoc). Concentration will depend on bottom hole temperature and desired slurry density. Selvol™ Premiol DWC50 can be used in slurries with a wide range of densities (15.6 ppg up to 17.1 ppg).
