CG613 is a synthetic polymer designed to reduce water loss from cement slurry into porous formations during the cementing process.
It maintains excellent fluid loss control while addressing common issues with polymer-based additives, such as reversed thickening times and reduced strength.
CG613 is primarily used in normal density cement slurry system.
It’s suitable for fresh water systems.
It operates effectively at temperatures below 180°C (356°F, BHCT).
Compatible with other additives.
The recommended dosage ranges from 0.6% to 2.5% of the total slurry weight (BWOC).
