Weighting Material Sag

This paper describes how applying different degrees of mixing -energy to an invert-emulsion drilling fluid affects rheological parameters and how this influences the sedimentation potential of weighting material from a drilling fluid. The paper presents results from a large scale factory application test and following laboratory
