Determining hydrocarbon reservoir production with a miniature multi-phase flowmeter

A wellbore production system comprising:

• a wellhead coupled to a wellbore fluidly coupled to a hydrocarbon reservoir containing a multi-phase reservoir fluid;
• a coiled tubing assembly configured to extend through the wellhead into the wellbore and flow the multi-phase reservoir fluid from the wellbore to a surface of the Earth;
• a multi-phase flowmeter coupled to the coiled tubing assembly and positionable in the wellbore by the coiled tubing assembly, the multi-phase flowmeter comprising a venturi oriented in along a longitudinal axis of the coiled tubing assembly, the multi-phase flowmeter comprising a greasing port extending from an outer surface of the multi-phase flowmeter into a void of the venturi, the void extending along the longitudinal axis of the multi-phase flowmeter, the multi-phase flowmeter configured to:
• sense a plurality of conditions of the multi-phase reservoir fluid, the plurality of conditions including a pressure, a differential pressure, a temperature, a bulk fluid flow rate, an electrical capacitance, and an electrical conductance of the multi-phase reservoir fluid;
• and
• transmit a signal representing the plurality of conditions of the multi-phase reservoir fluid;
• and
• a controller configured to perform operations comprising:
• receiving a signal representing the plurality of conditions of the multi-phase reservoir fluid from the multi-phase flowmeter;
• and
• determining, based on the plurality of conditions of the multi-phase reservoir fluid, a production condition of the hydrocarbon reservoir.
