What are drilling fluids?

Drilling fluids, also known as drilling mud, are specialized fluids used during the drilling of oil and gas wells. They serve multiple purposes, including lubricating and cooling the drill bit, carrying drill cuttings to the surface, maintaining wellbore stability, and controlling formation pressures. The composition of drilling fluids can vary, typically being water-based, oil-based, or synthetic-based, depending on the drilling requirements and environmental considerations. Proper management of drilling fluids is crucial for efficient, safe, and environmentally responsible drilling operations.
