Manganese tetroxide particles have a spherical shape of (4 µm) in size and specific gravity of (4.8 g/cm3) which leads to lower contact in particle-to-particle interactions [11,12]. Field studies show that when Manganese tetroxide is used in oil-based drilling fluids, there was less formation damage and high amount of productivity.
