... been designed which employs a combination of two different weighting agents viz. barite and manganese tetroxide (Mn 3 O 4 ). The use of such a combination as a weighting material in a drilling fluid provides both operational and monetary benefits. Manganese tetroxide is spherical in nature and has a...
