HR®-5 additive is a chemically modified lignosulfonate that retards the setting of cement. It is designed for use in wells with circulating temperatures between 125°F (52°C) and 206°F (97°C) – 290°F static (143°C).
HR-5 additive is compatible with the following:
Fresh or saltwater slurries
Most cement additives
All API cements
Bentonite cement
Pozmix® A cement
HR-5 additive provides the following benefits:
Increased concentrations of HR-5 additive enhance the predictability of cement thickening times.
Decreases the danger of over-retarded slurries at the top of a long cement column.
Provides early cement strength development.
Helps displace slurries at high rates while maintaining formation pressure.
