SUMMARY
1、 CG117 fluid loss additive is a synthetic polymer which is capable of effectively reducing water loss filtering from the slurry to porous formation during cementing process.
2、 Control fluid loss in both normal and high density cement slurries.
3、 Applicable in fresh water slurries, seawater slurries and slurries containing 2% CaCl2.
4、 Maintain suspension stability of cement slurries.
5、 Shorten transition time of setting cement, which is beneficial to prevent gas migration.
6、 Used below temperature of 180℃(356℉, BHCT).
7、 Compatible well with other additives.
8、 CG117 series consists of L-type liquid, L-A type anti-freezing liquid, S-P type high purity powder and S-D type dry-mixed powder.
