Product Description

G302 can control fluid loss through forming tight polymer film and enhancing viscosity of the aqueous phase.

Characteristics

G302 consists of water-dissolved macromolecules and other related additives.

Not toxic, non-brominated.

Normal dosage: 0.8%~2.0% (BWOC), controlling API fluid loss at less than 150ml.

Used in oil wells whose BHCT is between 40℃ and 120℃, to be combined with a retarder.

Has no harmful influence on compression strength.

Suitable for dry mixing.
