Systems and methods for analyzing multiphase production fluids

A system for analyzing a multiphase production fluid, the system comprising:

• a fluidic separation chamber;
• a fluidic separation chamber valve;
• fluidic piping configured to supply multiphase production fluid to the fluidic separation chamber through the fluidic separation chamber valve;
• a plurality of composite sensing modules vertically spaced within the fluidic separation chamber, each of the composite sensing modules comprising an inductive sensor comprising opposing inductive sensing elements displaced from one another across a vertically extending measurement portion of the fluidic separation chamber, and a capacitive sensor comprising opposing capacitive sensing elements displaced from one another across the vertically extending measurement portion of the fluidic separation chamber;
• and
• a fluidic supply and analysis unit in communication with the fluidic separation chamber valve and the plurality of composite sensing modules, the fluidic supply and analysis unit configured to
• communicate with the fluidic separation chamber valve to supply a multiphase production fluid to the fluidic separation chamber,
• communicate with the inductive sensor of each of the plurality of composite sensing modules to detect a height HW of a water phase column in the multiphase production fluid in the fluidic separation chamber,
• communicate with the capacitive sensor of each of the plurality of composite sensing modules to detect a height HO of an oil phase column in the multiphase production fluid in the fluidic separation chamber,
• communicate with the capacitive sensor of each of the plurality of composite sensing modules to detect a height HG of a gas phase column in the multiphase production fluid in the fluidic separation chamber, and
• convert the height HW of the water phase column, the height HO of the oil phase column, and the height HG of the gas phase column to production fluid phase volume fraction data, production fluid phase flow rate data, or both.
