Drilling fluids play an important role in the successful drilling applications of oil and gas wells. This role ofdrilling fluid in oil exploration and exploitation activities is similar to the blood circulation in the human body according tothe some researches. The most commonly used drilling fluids are water based fluids in the drilling applications. In this study,to investigate the performance of the ester-based drilling fluid in application of shale occurrence drilling was aimed. Thisstudy therefore was undertaken to evaluate the effect of different concentrations of shale occurrence on the rheologicalproperties of ester-based drilling fluid. The fluids used in this study were XB1000 refined from waste cooking oil as esterbased fluid and diesel oil refined from petroleum as oil-based fluid. Within this scope, experimental studies were conductedto obtain some properties such as plastic viscosity, yield point, and gel strength. The results showed that plastic viscosityincreased as solid percentage increased in both samples and insignificant shale swelling between the two oil mud fluidsshows same tolerance level. Thus, the synthetic-based drilling fluids can be used as a suitable alternative to the oil-baseddrilling fluids to curb environmental pollution.
