摘要： The present invention relates to the use of a buffered acid wash to reduce the amount of oil in cuttings associated with the use of an invert emulsion well fluid. The buffered acid wash is sufficiently acidic as to convert all of the surfactant in the invert oil emulsion from one charge species into another, but substantially prevents the fluid from becoming so acidic as to generate carbon dioxide.
