Multi-phase characterization using data fusion from multivariate sensors

A system for determining properties of a wellbore fluid, comprising:

• a first sensor configured to determine a first fluid property, the first sensor corresponding to a resonator;
• a second sensor configured to determine a second fluid property, the first sensor corresponding to a first optical sensor operational at a first wavelength;
• a third sensor configured to determine a third fluid property, the second sensor corresponding to a second optical sensor operational at a second wavelength;
• at least one processor;
• and
• memory storing instructions that, when executed by the processor, cause the system to:
• determine, based at least in part on the first fluid property, a fluid density;
• determine, based at least in part on one of the first sensor or the second sensor, a fluid fluorescence;
• determine, based at least in part on one of the first sensor or the second sensor, a reflected intensity;
• and
• associate the fluid density with at least one of the fluid fluorescence or the fluid reflection to determine a phase of the fluid.

A method for determining a wellbore fluid phase, comprising:

• receiving, from at least one sensor, fluid data for a fluid flowing through a wellbore;
• determining, based at least in part on the fluid data, a plurality of fluid properties;
• generating, based at least in part on the plurality of fluid properties, a visual pattern for the fluid;
• and
• determining, based at least in part on a shape of the visual pattern, a fluid phase.
