Also known as “drilling mud,” drilling fluids are used to drill boreholes into the earth. Their main functions include: cooling and lubricating the drill bit, flushing drill cuttings and moving them to the surface, providing hydrostatic pressure to prevent the uncased wellbore from caving in, and preventing formation fluids from entering the wellbore. Depending on drilling requirements, different types of drilling fluids are used: water-based (dispersed and non-dispersed), non-aqueous (usually referred to as oil-based mud), synthetic materials, and gaseous drilling fluid, which can utilize various gases. Particular fluids are chosen to minimize formation degradation and corrosion.
