SUMMARY
1、 CG610 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 normal density cement slurries, lightweight or high density cement slurries.
3、 Used below temperature of 204.4℃(400℉, BHCT).
4、 Applicable mixing water: from fresh water to salt-saturated water.
5、 Compatible well with other additives.
6、 CG610 series consists of L-type liquid, L-A type anti- freezing liquid, S-P type high purity powder, S-D type dry-mixed powder and S-T type dual-use powder.
