Abstract
Methods and processes for recycling base oils from spent invert emulsion drilling fluids may include frictionally heating a spent drilling fluid that comprises an invert emulsion and solids, wherein the solids are at about 50% or less by volume of the spent drilling fluid; and simultaneously evaporating oil and water from the invert emulsion at a temperature lower than an atmospheric boiling point for the oil.
