<p>THE INVENTION RELATES PARTICULARLY TO METHODS AND APPARATUSES FOR CHARACTERIZING WATER-IN-OIL OR INVERT EMULSION FLUIDS FOR USE IN DRILLING WELL BORES IN HYDRO-CARBON BEARING SUBTERRANEAN FORMATIONS. A FLUID STABILITY MEASUREMENT METHOD IS DESCRIBED. THE METHOD INCLUDES PLACING A SAMPLE OF AN EMULSION IN A GAP (235) BETWEEN ELECTRODES (205, 210), DISTURBING THE SAMPLE, MEASURING THE ELECTRICAL STABILITY OF THE SAMPLE, AND ESTABLISHING A RELATIONSHIP BETWEEN ELECTRICAL STABILITY AND TIME SINCE THE SAMPLE WAS DISTURBED.</p> |
