Description: an organo-mineral composition with particle dimension making up to 500 micron, density ranges from 1,03 to 1,10 g/cm3 due to hange of the mixture composition, moreover, it may be used in drilling fluid systems based on brines (density is up 1,5 g/cm3).

Application: in lost circulation control technology for pumping to the lost circulation zone in the form of a visco-elastic composition, where a tight plug is formed, which prevents lost circulation.

Recommended discharge: recommended pumping volume makes 20–40 m3.
