Selvol™ Premiol DWC-50

Premiol DWC-50High performance, mid to high range temperature technologySelvol™ Premiol DWC-50 is a powder-form fluid loss control additive for deep well applications that delivers high temperature performance (up to 150ºC) at cost levels below traditional high molecular weight polymers. At the same time, this advanced additive demonstrates excellent, cost-effective performance at low temperatures (50ºC to 60ºC). With a single product that functions across a wide range of conditions, the oilfield service industry can consolidate inventory of fluid loss control products.More information on Selvol™ Premiol DWC-50.

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).
