👉 Drilling fluids, also known as muds, are complex mixtures used in the drilling process to facilitate the removal of rock formations and to stabilize the wellbore. These fluids consist of water, oil, gas, additives, and various chemicals designed to perform multiple functions. Primarily, they reduce friction between the drill bit and the rock, cool and lubricate the drill string, carry cuttings to the surface, and provide pressure support to prevent well collapse. They also act as a cooling medium, remove heat generated during drilling, and can include chemical additives to enhance specific properties like viscosity control, weight reduction, and corrosion inhibition. The composition of drilling fluids is tailored to the specific conditions of the drilling site, ensuring optimal performance and safety.
