Oilwell Cementing Fluid Loss Additive
DESCRIPTION
l Specially designed for the application in low density cement slurry system.
l Generates thickening effect on the cement slurry and enhances cement slurry's suspension stability.
l Used blow temperature of 180℃(356℉, BHCT).
l Features with good salt tolerance which is up to salt-saturation, suitable for both fresh and salt water system.
l When applied, cement slurry system is stable with little free fluid.
l Good compatibility with other additives.
l Suitable for use with all API classes of cement.
l Mixed with water when applied and no water quality is required.
l The following technical data and parameters are of our standard type of CG210L. We are capable of catering tailor-made products and services upon receipt of customers' individual requirements.

Recommended Dosage in Fresh Waterand Moderate Temperature System |
Recommended Dosage in 18% Slat Water and Moderate Temperature System |
Recommended Dosage in 18% Salt Water and High Temperature System |
|
1.50±0.01g/cm3 (in fresh water, W/C=0.80, in 18% brine, W/C=0.90) |
5%(BWOC) or 0.60 gal/50kg cement |
6.5%(BWOC) or 0.78gal/50kg cement |
8%(BWOC) or 0.96gal/50kg cement |
Note: Dosage of standard CG210L is calculated based on 50kg /sack cement and shall be adjusted when different cement, mixing water and slurry density are applied. When used in high concentration salt water and high temperature conditions, the dosage shall be increased, confirmed dosage is to be finalized based on lab test result.
