A method for recycling an invert emulsion based drilling fluid, in which the invert emulsion based drilling fluid includes an oil component and an aqueous component. The method includes: mixing the invert emulsion drilling fluid with a emulsion clearing agent, wherein the emulsion clearing agent is a mixture of an anionic tensid and a non-ionic tensid; and separating the oil component of the invert emulsion drilling fluid from the aqueous component of the invert emulsion drilling fluid. The method preferably utilizes an emulsion breaking agent that is a combination of an anionic tensid, a non-ionic tensid and an alkyl polyglycoside tensid.
