The finest screen at that time could separate solids only larger than about 177 microns (API 80) from a normal drilling-fig circulating rate. Barite specifications restricted solids to sizes predominantly smaller than 74 microns (API sand). Hydrocyclones removed large quantities of barite from a weighted drilling fluid and were not generally used.

Barite (barium sulfate, BaSO4) contains 58.8 % barium and has a specific gravity of (4.2–4.5). The barite used in drilling fluid, which is normally impure, is of lower specific gravity as it contains other minerals such as quartz, chert, calcite, anhydrite, celestite, and various silicates. Also, it consists of other iron minerals, …

By far, the principal use for barite is as a "weighting agent" in oil and natural gas drilling. In this process, barite is crushed and mixed with water and other materials. It is then pumped into the drill hole. The weight of this mixture counteracts the force of the oil and gas when it is released from the ground.

drilling mud, in petroleum engineering, a heavy, viscous fluid mixture that is used in oil and gas drilling operations to carry rock cuttings to the surface and also to lubricate and cool the drill bit. The drilling mud, by hydrostatic pressure, also helps prevent the collapse of unstable strata into the borehole and the intrusion of water from water-bearing strata that may be encountered.
