US 2021/0080418 A1 · OIL RECOVERY SENSOR

Abstract

The present disclosure relates to systems and methods for measuring oil/water content in oil-water mixtures, regardless of the salinity of the mixture and regardless of air in the sensor pipe. In some embodiments, the oil content is measured using a dielectric sensor. It is determined whether the oil content is above or below a threshold. If the oil content is above the threshold, the oil content is reported using the measurement from the dielectric sensor. If the oil content is below the threshold, the oil content is reported using the measurement from the eddy current sensor. In some embodiments, which improve performance when there is air in the sensor pipe, two dielectric sensors with different geometries are used instead of the one dielectric sensor.

Dependent claims

A system for measuring oil content of a fluid, the system comprising:

an electrically insulating channel;
a first electrode disposed on an outside of the electrically insulating channel;
a second electrode disposed on the outside of the electrically insulating channel, wherein the first electrode and the second electrode are spaced apart along the electrically insulating channel by a distance L;
a capacitance meter connected to measure capacitance between the first electrode and the second electrode;
and
one or more processors configured to determine an oil content of a fluid contained in the electrically insulating channel based on the measured capacitance between the first electrode and the second electrode.
