FIELD: chemistry.

SUBSTANCE: invention relates to the use of a peeling material to increase the viscosity of a non-aqueous liquid base containing organophilic clay. Said peeling material comprises a glycerol carbonate and an alkoxylated alcohol having the formula: , where R is a linear or branched alkyl having 2 to 18 carbon atoms or an aromatic radical having the structure: , where R₁ is a branched or linear alkyl containing from 2 to 18 carbon atoms, R₂ is H or CH₃, R₃ is H or CH₃, a is from 0 to 12 and b is from 1 to 12. Also, the invention relates to a wellbore fluid composition and to a well treatment method. Invention is developed in dependent claims of the invention.

EFFECT: technical result is an increase in the viscosity of wellbore fluids.
