Oil Field Cementing

Selvol™ Polyvinyl Alcohol is perfectly suited for use as an oilfield fluid loss control additive in cementing applications. When mixed with Class H cement powder, water, a dispersant and defoamer, this non-ionic, low viscosity producing additive will prevent fluid from being lost to the formation in intermediate cementing operations. At bottom-hole circulating temperatures of up to 190°F, it is the most commonly used fluid loss control additive in the world.

An added benefit of utilizing Selvol™ Polyvinyl Alcohol in oilfield cementing applications is that it will not retard the set-time at bottom-hole circulating temperatures.
