The flush fluid's drilling chemicals component lubricates, cools, and shields cutting tools from corrosion. Hydrostatic pressure created by the drilling fluid in the borehole prevents liquids and gas from passing through.Drilling chemicalenables drilling mud to compensate for high-pressure zones encountered during drilling by increasing the hydrostatic pressure of the mud. The mineral's softness also enables it to act as a lubricant and keeps it from hurting drilling equipment while drilling.
