It's used to prevent anything coming back up the hole.
Drilling fluids, the circulating fluid for drilling operations, is a mixture of the fluid, the solid and chemical agents. It is usually known as the "mud" or the "blood of drilling" deriving from its distinctive significance.
The main functions of drilling fluids include providing hydrostatic pressure to prevent formation fluids from entering into the well bore, keeping the drill bit cool and clean during drilling, carrying out drill cuttings, and suspending the drill cuttings while drilling is paused and when the drilling assembly is brought in and out of the hole. The drilling fluid used for a particular job is selected to avoid formation damage and to limit corrosion.

What technology allows oil workers to produce a drill long enough to reach the oil?
Oil workers use advanced drilling technology, such as horizontal drilling and rotary drilling techniques, to produce long drill strings that can reach deep oil reserves. These methods involve using specialized drill bits and equipment that allow for extended reach and precise drilling angles. Additionally, the use of drilling mud helps stabilize the wellbore and cool the drill bit, facilitating the extraction of oil from great depths.
What is in invert drilling mud?
Invert drilling mud, also known as invert emulsion mud, consists primarily of a water-in-oil emulsion, where water droplets are dispersed in an oil phase, typically containing synthetic or mineral oils. This type of drilling fluid includes various additives such as emulsifiers, weighting agents, and surfactants to enhance its performance and stability. Invert drilling mud is favored for its superior lubricating properties, reduced fluid loss, and improved wellbore stability, making it particularly useful in challenging drilling conditions.
What is oil emulsion mud?
Water based drilling fluid that contains dispersed oil or synthetic hydrocarbon as an internal phase.
