The paper is devoted to comprehensive studies of the colloidal stability and rheological properties of inverse emulsions based on technical rapeseed oil and developing on their base recommendations for using these environmentally friendly components as the base for synthesis drilling fluids. The study of the properties of emulsions was carried out depending on the concentration of oil (from 50 to 90 vol.%), the concentration of the emulsifier (from 1 to 3 vol.%) and temperature (from 20 to 80 °C). Stable invert emulsions were obtained, which retain their properties with increasing temperature, which indicates the possibility of their practical application as components for synthesis environmentally safer drilling fluids
