Barite–Micromax mixture, an enhanced weighting agent for …
Weighting agents are mixed with the drilling mud to provide the high density required to control high-pressure high-temperature (HPHT) wells throughout the drilling operation. Solids sag occurs when the weighting agent separates from the liquid phase and settles down, causing variations in the drilling fluid density. This study evaluates barite–manganese tetroxide …

A weighting material such as manganese tetroxide is used to formulate drilling fluids at density requirements for deep drilling because of its high specific gravity (i.e. 4.8). However, the microsized particles, surface charge, and presence of biopolymers increase the tendency to agglomerate and, thus, promote sagging.
