Polymers are recently found and still developing materials to overcome some drilling problems where conventional drilling fluids are not satisfactory enough. Simply, they are the best materials to use since they are non-toxic and do not cause serious environmental problems. In addition, polymeric drilling fluids may have properties such as better carrying capacity, less fluid loss, and thinner filtration cake depending on their composition and concentration. In this research, rheological parameters of two different bentonite types (API, non-API), and two different polymers (XC and PAC) at ten different concentrations (between 0% and 1% in weight) were determined. Experiments were carried out to observe for changes not only in rheological parameters like viscometer readings, but also in mud weight, pH, fluid loss and filtration cake. Three sets of experiments were performed for each mixture to reduce the experimental errors and to see the repeatability. Finally a software is developed for rheological model identification.
