DRILLING FLUIDS FL-1. Introduction The principal functions of drilling fluid are to: Drilling fluids are fluids that are used during the drilling of subterranean wells. They provide primary well control of Control subsurface pressures, maintaining well control;. subsurface pressures by a combination of density and any Remove drill cuttings from beneath the bit and circulate additional pressure acting on the fluid column (annular or them to the surface;. surface imposed). They are most often circulated down the Maintain wellbore stability, mechanically and chemi- drill string, out the bit and back up the annulus to the surface cally;. so that drill cuttings are removed from the wellbore. Transmit hydraulic energy to the drill bit and downhole tools;. Drilling fluids have a number of alternative names, acronyms Cool and lubricate the drill string and bit;. and slang terms used within Allow adequate for- the industry.
