Oil Field Cementing Applications
Our Selvol™ polyvinyl alcohol (PVOH) resin works ideally as a fluid loss control additive in oil field cementing applications.
When mixed with Class H cement powder, water, a dispersant and a defoamer, this nonionic, low viscosity-producing additive prevents fluid from being lost to the formation in intermediate cementing operations. At bottom-hole circulating temperatures of up to 190 degrees Fahrenheit, it’s the most common fluid loss control additive in the world.
Additionally, using Selvol PVOH in oil field cementing applications doesn’t slow the set time at bottom-hole circulating temperatures.
