Using two types of nanoparticle (NP) additives inwater-based drilling fluids have been studied in this paper. Three major drillingmud systems, namely potassium chloride (KCl) as a basic mud, KCl/aluminumoxide (Al2O3) NPs, and KCl/iron (Fe2O3) NPs, were prepared and studied forenhancement of rheological properties and shale inhibition. It was found that thedrilling mud contained NPs in concentrations of 0.25, 0. 5, 0.75, and 1 g. Al2O3and Fe2O3 NPs added to KCl/polymer mud systems resulted in a 50% and 30%change in shale volume, respectively. The results demonstrated that incorporatingNPs into the KCL mud system enhanced shale inhibition. Adding NPs to the KCLWBMincreased yield point, plastic viscosity, and gel strength. The COF of KCLpolymerwas reduced by 48% and 34% when added Al2O3 and Fe2O3 NPs at 0.5and 0.75g, respectively. When Al2O3 and Fe2O3 NPs were used, particularly at 1g,the amount of mud filtration decreased from 13.1ml to 8.8 ml and 8.4 ml,respectively. Overall, it was found that adding Al2O3 and Fe2O3 NPs to the KCl-WBM can improve rheological, swelling, and filtration properties as well aslubrication.
