drilling fluid (mud)

Drilling fluid, commonly known as mud, is a specially formulated liquid used during drilling for oil, gas, or minerals. It serves multiple purposes: lubricating and cooling the drill bit, carrying broken rock (cuttings) to the surface, maintaining pressure to prevent well blowouts, and stabilizing the walls of the drilled hole. The fluid's properties are carefully controlled to ensure safety, efficiency, and safety of the drilling operation. It can be water-based, oil-based, or synthetic, depending on the geological conditions and requirements. Overall, drilling mud is essential for efficient and safe subterranean drilling.
