Key words: wellbore stability, non-dispersing mud, tall pitch, hydrofobisation, moisturizing property.

РThe paper focuses on ensuring wellbore stability whilst drilling through shale formations. The solution to the problem involves non-dispersing muds.  The authors present the results of using a by-product of the wood-processing industry, namely, tall pitch, as the main source of  fatty and resin acids.
