SUMMARY

1、  CG613 series products are polymer-type cementing fluid loss additives, which can effectively control the fluid loss of the cement slurry toward the formation during cementing.

2、  Prevent the reversal of thickening time and strength with temperature.

3、  Mainly suitable for normal density cement slurry system.

4、  Applicable temperature: below 180°C (356°F, BHCT).

5、  Applicable mixing water: from fresh water to half-saturated salt water.

6、  Compatible well with other additives.

7、  CG613 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.
