Specification :

1. Property
It' s a drilling fluid additive made basically from powder cationic asphalt with special technology. Its cylindrical grains are not only handy for use on site and safe for workers but also extremely easy to be dispersed in drilling mud and the particle size when dispersed is smaller than 150# mesh.

2. Quality Indexes
Terms Standard indexes
Appearance Black cylindrical grains
Water content, % d10
Oil soluble content % e50
Blocking capacity, ml d40
HTHP FL ( ml/ 30min) d25
Electropositivity Positive charge

3. Use
� It can serve as a blocking agent, locking fracture-growing formations while drilling to prevent occurrence of unstable well walls;
� IT functions well in reducing HTHP filter loss and protecting the oil-bearing formation;
� It also lubricates to reduce the torque of drilling tools;
� It does not foam in drilling mud.
When used as an agent to reduce filter loss, the recommended dosage is 1-2% . When used as a blocking agent, the recommended dosage is 3-5%

4. Storage & Package
25Kg net sealed in 4-in-1 compound paper bag with plastic lining. During storage and transport see that the bag is intact as the product is water soluble. But its property is not affected even if it becomes damp.
