drilling fluid

Drilling fluid, also known as mud, is a special liquid used during the drilling of wells, such as for oil or gas. Its main functions are to cool and lubricate the drill bit, carry rock cuttings to the surface, and maintain pressure to prevent the well from collapsing or exploding. Drilling fluids can be made from water, oil, or synthetic base, combined with various additives to control its properties. Properly managed, they ensure safe, efficient drilling operations and protect the environment.
