- Benefits
- Selvol™ Premiol MRC provides excellent fluid loss control at temperatures from 175°F - 250°F
- PVA-based powder
- Non-retarding
- Compatible with multiple additives
- Low surface rheology without settling
- Further rheology generation at down-hole conditions
- Mixable at high densities
- Environmentally friendly
- Easy to handle and design
- Lower in cost than other high temperature fluid loss additives
- Meets industry standards for fluid loss control agents
- Adjustable rheology
- Product Highlights
Selvol™ Premiol MRC is a non-retarding, fluid loss control additive designed to provide for fluid loss control up to 250°F with excellent surface and downhole rheology.
Typical Selvol™ Premiol MRC concentrations range from 0.75% to 1.75% by weight of cement (%bwoc). Concentration will depend on bottom-hole temperature and desired slurry density.
