ABSTRACT:
A method is provided for characterizing emulsion stability to evaluate suitability of the emulsion for use as a drilling fluid in drilling subterranean boreholes. The method provides a supplement or alternative to the standard method of determining Electrical Stability of the emulsion. In the method of the invention, Breakdown Energy is calculated. Breakdown Energy can be measured at the same test point as Electrical Stability. A digital storage oscilloscope and a computer are used in addition to an electrical stability meter.
