Previous studies and lab experiments show that manganese tetroxide (Mn 3 O 4) is a better weighting agent and represents an excellent alternative to barite and potassium formate. Manganese tetroxide retains relatively high specific gravity and small particle size, which reduces particle settling and sagging in high mud weight formulations.

9/1/2020· For the drilling mud to prevent blowout and suppress the formation pressure, its formulation usually involves a weighting material such as barite, ilmenite, manganese tetroxide, or calcium carbonate which is added to the drilling fluid to obtain the desired density (Rugang et al., 2014). Consequently, these highweight additives, are the main
