The selection of the relevant components the drilling of 5mud can reduce the occurrence of negative physical-chemical phenomena observed between shales and drilling mud. The purpose of laboratory examination was to estimate the impact of different polymer inhibitors for hydration of clays and shales. A laboratory test were performed in order to estimate the concentration of polymer inhibitors in preventing the phenomena taking place in contact with the shale rocks – drilling mud. Also, research the influence a drilling fluids containing different kinds of hydration inhibitors on swelling and clays and shales dispersion.
