Rheology of the water-based drilling fluid can be easily altered using the favorable additives to contribute to better performance during drilling operation, although bentonite is a major ingredient of water-based drilling fluids for this purpose. Still, additional contribution of other additives in efficient functioning of the drilling fluid becomes very important for various situations. The present review paper discusses the effect of various additives in the water–bentonite suspensions, which is base suspension of the majority of water-based drilling fluid. Effects of natural polymer, synthetic polymer, nanocomposite, etc. on rheology of water–bentonite suspensions have been reviewed based on the past researches and recent advances made in this field. Considerations have also been given to study the behavior of these additives at elevated temperatures. %8 2018-03-26
