Various embodiments disclosed relate to methods of cleaning invert emulsion drilling fluids. In various embodiments, the present invention provides a method of cleaning a drilling fluid. The method includes cleaning a used invert emulsion drilling fluid that includes drilled cuttings to form a cleaned invert emulsion drilling fluid. The cleaning includes processing the used invert emulsion drilling fluid in a separator to remove at least some of the drilled cuttings therefrom.

Methods of cleaning invert emulsion drilling fluids

Beneficiating particulate additives by removing contaminants or minerals that impact the quality and specific gravity of the particulate additives may be achieved via dry solids separation technologies. For example, an air classifier, an electrostatic separator, and a combination thereof may be used to produce a beneficiated particulate additive comprising less than 40% of drill solids by weight of the beneficiated particulate additive.

Beneficiating weighting agents

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.
