Pneumatic drilling fluid (or gas-based mud; air-based mud) is used to drill in areas where the use of conventional drilling fluids is not feasible. They are used to drill in depleted zones, areas with low reservoir pressures, and where a loss of circulation is predicted. Pneumatic drilling fluid… View Full Term
