    Barite sag is intensified at the low side, by the very low velocity present in that area of the well. Flow loop testing has proved that a sag mechanism can be set up at shear rates as high as 95 sec^-1. In reaching these conclusions many wells were analyzed and only one incidence was found where barite sag was reported while drilling.
