- G301 consists of cellulose derivatives and other additives.
- Appearance: reddish brown powder, non-poisonous and non-odor.
- Normal dosage: 0.8% ∼ 2.0% (BWOC).
- APL fluid loss: ≤ 150ml.
- It’s almost no free fluid.
- Dissolve easily.
- No obvious thickening effect on cement slurry, show a slight thixotropic property.
- Has certain retarding property which can be eliminated by using accelerator, so it can be used easily to design right-angle thickening slurry.
- Enhance the compression strength of cement gravel.
- Has a definite salt-resisting property.
- It is applicable to oil wells whose circulating temperature is between 40℃ to 120℃.
- It will be more effective combining with USZ friction reducing additive.
- It can be mixed with or without water.

Fluid Loss Control Additive for Oil Well Cement
Product Description :
G301 can enhance the viscosity of water phase in cement slurry and form aggregated chains of polymer to plug the pores in mud cake. So it can reduce the permeability of mud cake and to control fluid loss.
