Abstract
A method of determining wettability may include: measuring an electrical property of a drilling fluid; and correlating the electrical property to wettability.
Claims19
A method of determining wettability of direct emulsion drilling fluid comprising:
- measuring an electrical stability (ES) voltage of the direct emulsion drilling fluid;
- determining if the measured ES voltage is below a threshold ES value corresponding to water wet direct emulsion drilling fluids;
- determining if the measured ES voltage is above a different threshold ES value corresponding to oil wet direct emulsion drilling fluids;
- and correlating the electrical stability voltage to wettability of the direct emulsion drilling fluid.
1 more element
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.
