Claim 8:
9. A system to determine wettability of direct emulsion drilling fluid comprising:
a conduit fluidically coupled to a wellbore and configured to receive a drilling fluid from the wellbore;
an electrical stability (ES) meter comprising electrodes in electrical communication with the drilling fluid; and
a signal processor communicably coupled to the ES meter configured to receive an output signal comprising ES voltage from the ES meter, determine if the measured ES voltage is below a threshold ES value corresponding to water wet direct emulsion drilling fluids, determine if the measured ES voltage is above a different threshold ES value corresponding to oil wet direct emulsion drilling fluids, and correlate the output signal to wettability of the direct emulsion drilling fluid.
