Barite segregations is a phenomenon that can lead to dire problems when not controlled properly. Many methods have been discovered and tested to reduce the effect of barite sagging. This research looks into two different drilling fluids, freshwater and seawater based. The experimentation looks at varying concentrations of Flowzan and Prehydrated Bentonite and seeing how that effects the sag factor of the fluids. For the freshwater samples, we found a critical Flowzan concentration that shows the highest sag factor. For the seawater though, we found a general decrease of sagging with the increase of PHB concentration. The findings would be more conclusive if we tested for a wider range of concentrations for both Flowzan and PHB.
