👉 Drill fluid, also known as mud, is a critical component in the drilling process used to facilitate the removal of rock formations from the earth's surface or subsurface for exploration and extraction of natural resources. It serves multiple purposes: it cools the drill bit, removes cuttings from the wellbore, stabilizes the formation to prevent collapse, and provides lubrication to reduce friction between the drill bit and the rock. Additionally, it acts as a carrier medium for additives that enhance its properties, such as weight control, density modification, and chemical compatibility with the formation. These additives can include polymers, surfactants, and biocides, which help in maintaining the fluid's performance under varying conditions and ensure efficient drilling operations.
