The importance of using lubricating additives lies in the reduction of friction due to the adsorption layer on the surface of the phase interface. The use of lubricating additives helps to increase the penetration of the bit and the mechanical speed of drilling. Lubricating additives also reduce friction between drill pipes and well walls. Drilling mud treated with surface-active substances (surfactants) are also known to have lubricating properties.enlubricating propertiesArticle62-403
